Inside every living thing lives millions of cells Essays - Biology

Inside every living thing lives millions of cells that help our body perform chemical reactions and functions that help us survive. Inside this very cell holds different organs, called organelles, and different products of the cell. Each part of the cell has its own function, like a factory that manufactures products. Plant and animal cells are alike in several ways. Plant and animal cells are both eukaryotic cells, which means both cells include a nucleus. They have several features in common, such as the presence of a cell membrane, and cell organelles, like the mitochondria and endoplasmic reticulum. The cell membrane is a semi-permeable structure. It only allows some things in (such as glucose,) and only some things out. (cellular waste is an example.) In the center of the cell is the nucleus, the brains of the cell. The nucleus controls what every part of the cell does. For example, it may tell the mitochondria to break down more food because the cell does not have enough energy. Of course, plant and animal cells also have many different features. This so the cell is able to supply the needs of the organism. A plant needs sunlight in order to survive, but animals do not. Because the needs of animals and plants are different, their organelles vary also. In addition to the cell membrane, plant cells also have a thick cell wall. This is to help the plant keep its long, rectangular shape. When looking under a microscope, cell walls are a great way to distinguish plant cells from animal cells. Plants are also autotrophs; they produce energy from sunlight through the process of photosynthesis, for which they use cell organelles called chloroplasts. However, plant cells do contain mitochondria. While both plant and animal cells contain vacuoles, plant cells have one large central vacuole that can take up to 90% of cell volume. In plant cells, the function of vacuoles is to store water and maintain turgidity of the cell. Animal cells, on the other hand, have one or more small vacuoles. Vacuoles in animal cells store water, ions and waste. They also do not have chloroplasts. In animal cells, energy is produced from a simple sugar called glucose, via the process ofcellular respiration. Cellular respiration occurs in mitochondria on animal cells, which are structurally somewhat analogous to chloroplasts, and also perform the function of producing energy. Lysosomes are membrane-enclosed organelles that contain an array ofenzymescapable of breaking down all types of biological polymersproteins, nucleic acids, carbohydrates, andlipids. They can only be found in animal cells. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differen ces in the materials that have been taken up for digestion.

How to Make a Stem and Leaf Plot

How to Make a Stem and Leaf Plot When you finish grading an exam, you might want to determine how your class performed on the test. If you do not have a calculator handy, you can calculate the mean or median of the test scores. Alternately, it is helpful to see how the scores are distributed. Do they resemble a bell curve? Are the scores bimodal? One type of graph that displays these features of the data is called a stem-and-leaf plot or stemplot. Despite the name, there is no flora or foliage involved. Instead, the stem forms one part of a number, and the leaves make up the rest of that number.   Constructing a Stemplot In a stemplot, each score is broken into two pieces: the stem and leaf. In this example, the tens digits are stems, and the one  digits form the leaves. The resulting stemplot produces a distribution of the data similar to a  histogram, but all of the data values are retained in a compact form. You can easily see features of the students’ performance from the shape of the stem-and-leaf plot. Stem and Leaf Plot Example Suppose that your class had the following test scores: 84, 65, 78, 75, 89, 90, 88, 83, 72, 91, and 90 and you wanted to see at a glance what features were present in the data. You would rewrite the list of scores in order and then use a stem-and-leaf plot. The stems are 6, 7, 8, and 9, corresponding to the tens place of the data. This is listed in a vertical column. The ones digit of each score is written in a horizontal row to the right of each stem, as follows: 9| 0 0 1 8| 3 4 8 9 7| 2 5 8 6| 2 You can easily read the data from this stemplot. For example, the top row contains the values of 90, 90, and 91. It shows that only three students earned a score in the 90th percentile with scores of 90, 90, and 91. By contrast, four students earned scores in the 80th percentile, with marks of 83, 84, 88, and 89. Breaking Down the Stem and Leaf With test scores as well as other data that range between zero and 100 points, the above strategy works for choosing stems and leaves. But for data with more than two digits, youll need to use other strategies.   For example, if you want to make a stem-and-leaf plot for the data set of 100, 105, 110, 120, 124, 126, 130, 131, and 132, you can use the highest place value to create the stem. In this case, the hundreds digit would be the stem, which is not very helpful because none of the values is separated from any of the others: 1|00 05 10 20 24 26 30 31 32 Instead, to obtain a better distribution, make the stem the first two digits of the data. The resulting stem-and-leaf plot does a better job of depicting the data: 13| 0 1 2 12| 0 4 6 11| 0 10| 0 5 Expanding and Condensing The two stemplots in the previous section show the versatility of stem-and-leaf plots. They can be expanded or condensed by changing the form of the stem. One strategy for expanding a stemplot is to evenly split a stem into equally sized pieces: 9| 0 0 1 8| 3 4 8 9 7| 2 5 8 6| 2 You would expand this stem-and-leaf plot by splitting each stem into two. This results in two stems for each tens digit. The data with zero to four in the ones place value are separated from those with digits five to nine: 9| 0 0 1 8| 8 9 8| 3 4 7| 5 8 7| 2 6| 6| 2 The six with no numbers to the right shows that there are no data values from 65 to 69.

Business Research for Decision Making, Red Tomatoe Company Essay

Business Research for Decision Making, Red Tomatoe Company - Essay Example bout the company is that the top management came from the ranks of the JRT and this could be identified as one of its strengths because these people are familiar with the â€Å"ins and outs† of the company. Unfortunately, the company is on the rocks because key personnel started leaving last year because they realized that they have â€Å"no future with JRT†. This backlash could be detrimental to the company because it had previous plans of expanding in the future. With this, this paper would thresh out the problems associated with the human resources (HR) planning of JRT and seek out the viable solutions to these problems. The previous HR consultant conducted preliminary interviews within the organization, undergone research of the produce industry and consulted other business cases with similar challenges. It has been found out that â€Å"Juicy Red Tomato Company needs to invest in retention not only of its managerial personnel, but also front-line production employees. In addition, JRT needs to improve communication between production and operations, possibly by enhancing technology used by the company as a whole†. With regards to organizational structure, it has been observed that the JRT has the traditional structure. According to Grinnell and Apple (1975), there are five general indications that the traditional structure may not be adequate for managing projects: Our observations agree with what Green and Apple (1975) identified as the problems that arise with the traditional organizational structure. In fact, many companies do not realize the necessity for organizational structure to change until it is too late. Management looks externally (i.e., to the environment) rather than internally for solutions to problems. A typical example would be that new product costs are rising while the product life cycle may be decreasing. Should emphasis be placed on lowering costs or developing new products? If JRT assumes that an organizational system is composed of both

Their Eyes Were Watching God Essay Example | Topics and Well Written Essays - 500 words - 1

Their Eyes Were Watching God - Essay Example The movie was adapted and reproduced by Oprah Winfrey's Harpo Studio, and directed by Darnell Martin. Winfrey was the main host for the show. Its teleplay was done by Janie Crawford (Halle Berry), Teacake (Michael Ealy), Jody Starks (Logan Killicks), along with Mayor Joe Starks (Ruben Santiago-Hudson). Oprah Winfrey is immensely admirable, owing to her encouraging rise to fame due to her determined pursuit of quality and because of her wish to leave something optimistic for the world. However, her description of this most thoughtful and uplifting novel fell short of grasping Ms. Hurston’s brilliance (Hagopian 1). The film focused almost totally on the love story between transformed playboy, Tea Cake, and Janie Crawford. She missed the fact that there were other layers to the book such as the studies in developmental cultural anthropology and psychology. Crawford’s life with Tea Cake lasts for only about a year and a half (Hagopian 1). However, the film made it appear as though the companionship lasted much longer. Even though, it was the most noteworthy relationship of Crawford’s life, through it, Janie acquires the identity and voice that she has been denied for past 37 years. Also, through that voice, Janie saves herself from prison. The love story in the movie outshines the character development in the film. In reality, that is what the film is loomed on, a study in personal development and character (Hagopian 1).

Television And American Society Essay Example for Free

Television And American Society Essay Introduction Television Programs are aimed at entertainment. In the United States, most of the television programs in existence with the stated aims and objectives, owe their initial background to the practical situation and past experiences encountered by the blacks. When blacks are mentioned, the issue of racial discrimination automatically opens chapter.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The initial situation and experiences of the blacks is characterized by racial discrimination.   The initial social positions, the blacks were housemaids, whites’ cooks, whites’ â€Å"mammies† and other sorts of servants.    They were also seen as con artists and even deadbeats.  Ã‚  Ã‚   The technology of the televisions came up in some environment, which was completely unfamiliar to these blacks. The blacks occupied less inferior positions of baby sitters and nurturers for the white, to cater and manage the households of the whites and to the greater degree, restoration of balance and harmony in the house holds of the whites.   The whites were very comfortable to entrust the black on these roles.   However, more responsible social and civic responsibilities were denied the blacks by the whites. (Durham Kellner, 450) The blacks had an appreciated talent to amuse the whites through humor and this is the most significant tool to their success in the maintenance of humor in television programs. The black and the Whites occupied separate and unequal worlds in their existence, in terms of material and discursive attributes. Television programs and Blackness The programs aimed at entertainment in the United States are a good avenue to pass the information on intertextual and autobiographical issues of the blacks. (Durham Kellner, 452)   The blacks possesses an inherent talent of creating humor in a show whose amusement is so strong as to blind the culturally offensive message put across by the show.   The show exhibing blackness covers the institutional and cultural programs all of which are characterized by race and gender. The centre of interest in these television programs is the African American in all areas of its setting; aesthetic, context and narrative.   (Newcomb, 564)   The highlights of the entertainment programs usually attack fields such as class, gender, religion, colour and culture all visionalized, in the dominant angel of social location and cultural context to the African American (Williams, 110) The television program raises an attitude of hegemony whereby social and cultural forces emerge as influencing factors of political rule and domination.   Through these television entertainment programs, the actors make use of their physical and material resources, very inherent and talented towards an entertainment to others.   The recipient society interprets the presentation as an art, an entertainment or leisure. These people see the natural world as being internal to them and also in direct personal relationships with other people they encounter.   (Williams, 112) According to hegemony dominant messages inherent in African Americans are disguised as fictional entertainment in the United States.   These are a great assumption taken with respect to this scenario that the sender and the receiver interpret the message of the program in the same understanding.   The sender is making use of the inherent talent of humor and experience to come up with a message whose consequences are of political concern, since the control of these messages is a form of political control.   The audience of the program may come up with multiple meanings of the message that were not a priory.   Examined, controlled for or asked for (Newcomb, 565)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The television programs are a form of ritual communication whose aim and goal is to maintain the society and to represent the shared beliefs of the society.   The programs create an invisibility of the African American and an authorized representation by the white of the blackness. The television programs portray blackness and black themes for the purposes of entertainment to the whites due to the humorous attribute associated with the Africans.   The white producers take this advantage of audience appreciation and they stage the African humor at the expense of blacks.   The black Americans are left suffering out of the social problems confronting them.   The humor in the programs is out of the programs highlights of racism and sexism, which have got great social impact and cultural meaning to the audience. (Williams, 110) The programs present blacks playing subservient roles in the society and stereotyping the blacks while still the humor out these is enjoyed.   In first instances amusement created by the program blinds the offensive side.   Cultural and racial politics in the programs is the cause of humor to the whites.   The programs cores are further unfair to the African Americans by considering just as minor and a coincidental theme of the play, the social and the cultural facts of â€Å"blackness† It is the responsibility of every means of communication to uplift the ethical and moral standards of the society.   This target is practically defeated by the television programs aimed at entertaining the audience as part of leisure.   The televisions present programs, which highlight the use of drugs. Involvement in sex, acts of rebellion and extreme deviance behavior of the individuals. These issues are humorous and attract the audience but the far reaching consequences are towards the lowering of the ethical and moral standards of the society.   The programs also exhibit a sense of upward social mobility of the blacks and the replacement of black urban poverty with middle class affluence and yet retain the humor of the audience.   (Newcomb, 568)   Conflicts as age and suspicion based on race and colour are associated to the central elements of the contemporary America way of life by the programs.   This portrays the life of Americans to be a type of middle class family life (Newcomb, 569) The Americans are making all efforts to fight all form of racial and class discrimination.   The Americans are also determined to fight gender discrimination in terms of sex and age.   The social ills of drug abuse sexual abuse, deviance and rebellion are also practically out of the Americans policies.   However the television programs structure and viewpoint are contributing factors to defeat these aims and objectives. They portray to the world what is the position of African Americans, which is not a part of the modern American society.   The views and perspectives of these programs highlight the social locations and experiences subjected to the African Americans.   The program highlight situation comedy, variety, talks among others, which in totality operate vividly, and comfortably within the conventional and aesthetic boundaries of African Americans. (Newcomb, 570)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Morality issues circumvent around racism and this is a representation of the blacks in the society as per the television programs in the United States.   The television programs also features badly on the state of education and unemployment as negatively affecting the African Americans in the urban areas of the United States.   The programs also fail to address some very crucial issues that affect so many blacks in the United States. The audiences are not restricted to the programs representation of the African Americans and therefore they should be examined and their effects of derailing the meanings and pleasures correctly checked. The blacks’ presence in the United States is threatened with race, gender, class and power and inequalities related to these are a result of prejudice. (Newcomb, 571) Racial invisibility and colour blindness integrate Black characters into hegemonic white worlds.   This appeal to visions of colour blindness and universal harmony.   The uniqueness of the blacks in the shows is the appealing factor to create humor and a sense of fitness in a normative television universe.   The inherent victimization, anger and irrationality in the blacks at the shows, due to the pains of exclusion from society are a cause of humor to the audience.   This in the truest sense is racial prejudice.   (Durham Kellner, 447)   In the programs the whites acts the position of sympathizers for the elimination of this prejudice. The programs subvert American values bearing in mind that the effect of any communication is to persuade the audience to change attitudes, to modify behaviour and to take part in socialization. Any form of communication helps to maintain the values of a society and to represent the shared beliefs. These programs are responsible for production of dominant ideologies so influential as to take the audience into a dreamland. (Williams, 110) Conclusion The programs bring out the blacks as living simple and linearly dimensional lives in a segregated universe.   They are seen to be subjected to the challenges of domestic lives such as child rearing, embarrassments, and awkward situations among others.   Modern America is reduced to ancient behaviours of race relationships characterized by conflict, tension and apartheid and the African Americans dependent on cultural pluralism.   These programs make use of cultural politics within blackness to constantly modify the African Americans life, and comprehensively explain the position of an American from the point of view of an African American.

Energy Deregulation :: essays research papers

As we have witnessed the rolling blackouts and emergency alerts throughout many parts of our state of California within the past 12 months, there is a question waiting to be answered. Why do we have an energy crisis when there are other states that are doing just fine? Before we come to any hasty conclusion, let us ask ourselves what happened to the energy policy during the mid 90s? During that period the electric utilities went from being highly regulated to being deregulated following the trend in successful deregulation of many industries such as airline and telecommunication industries. The concept that deregulation will bring more competitive prices and better services to the public, undermined the negative potentials of the free market system. Deregulation bill must be abolished because it brings higher electricity prices, lower reliabilities of electricity, and also it threatens to drag down our economy along with it. First, we have seen a nation-wide increase in both wholesale and retail electricity prices. In California as an example, the wholesale prices increased seven times last year compared to 1999 (Kahn and Lynch 13). The average residential electric bill almost doubled from $40 to $80 in San Diego when the SDG & E’s retail price freeze ended in June 2000.1 According to Washington Governor Gray Locke, â€Å"the whole energy prices have gone up from ten to twenty times the prices of a year ago (1). In New York, more specifically in New York City and parts of Westchester County which are one of the first areas in the country to deregulate retail prices entirely, the retail rates have increased almost 30% (Eisenberg 47). This is bad when you consider that ones that are going to be most hurt from these unreasonably high electricity prices will be the individuals and families that are in the low-income bracket. Second, the reliability of electricity was compromised throughout many parts of our state, affecting both residential and business sectors. On June 14, 2000, about 100,000 customers were blacked out in San Francisco Bay Area (Kahn and Lynch 9-10). According to Lorenco Goncalves, the CEO of California steel industries, â€Å"We were interrupted 14 times this month [January] compared to not once from 1987 to 1998. So many other industries depend on what we send them†¦If they can’t depend on my products, they will [buy them] elsewhere† (Wood and Sherer). These uncertain interruptions are causing a lot of damage in our economy.

Natural Law and Sexual Ethics by Janet Smith Essay

I am honored to be among the lecturers in this series on natural law. Many of the speakers are among my heroes and friends. One of my heroes, Alasdair MacIntyre, used one of his favorite terms in his talk: he spoke of â€Å"plain persons† and their grasp of morality and natural law in contradistinction to the experts and professional philosophers and their grasp of these matters. A few years ago in Dallas he gave a talk entitled â€Å"Do plain persons need to be moral philosophers? † When I was asked to give the response to his talk, I was most honored because I considered Prof. MacIntyre one of the foremost moral philosophers in the world and it was a thrill to comment on his work. I felt dreadfully underqualified — I felt like some high school kid going up against Larry Bird — until I realized that I need not respond as an expert, as a moral philosopher of his caliber, but that I could respond as the quintessential plain person — for that is what I am. After all, I am Janet Smith, daughter of John and Anne Smith; I grew up at 5 Hill Street and went to Home Street School — I could go on but it is all very plain. The point I am making here is not merely a flip one — designed to ease us into more serious matters through an attempt at humor. There is a serious point here — natural law, is the â€Å"plain person’s† morality — in a sense it is simply plain old common sense. There are profound and sophisticated ways at explaining natural law, but the practiceof reasoning in accord with natural law principals, according to the theory itself, is natural to plain persons — that is, natural to all mankind for natural law holds that many of the most fundamental principles of moral reasoning are obvious, that is easily known by all. Yet, in spite of the plain commonsensicalness of natural law, it can seem shocking and provocative in many ways, for like natural law, plain old common sense does not command a lot of followers these days and can be shocking when juxtaposed to the values of our times. My talk is going to be very basic in several respects. It will review some of the basic principles that other speakers have covered, some in depth, some more in passing. It will also be very basic in being the one talk that attempts to make an application of natural law to concrete moral issues; issues in the realm of sexual ethics. My job is not to justify natural law ethics but to explain it and apply it. As did many of the earlier speakers I will largely be following the thought of Thomas Aquinas on these matters and of Aristotle from whom Aquinas learned many of the principles that informed his teaching on natural law. I shall also incorporate into my arguments the thought of another stellar natural law theorist, still alive and well: I shall make use of the work of Karol Wojtyla, now known as Pope John Paul II. I will refer to him as Wojtyla simply because I do not want to be thought to be invoking his authority as Holy Father; I cite him simply as a philosopher who has made great advances of our understanding of natural law, particularly in regard to sexual ethics. So let me begin with a review of the principles of natural law. As several other speakers have noted, Aquinas maintains that the first principle of natural law is â€Å"do good, avoid evil†. As he notes, that is a self-evident principle and obvious to all; if we want to be moral we should do good and avoid evil. No controversy here. The question is, of course, what is good and what is evil and how to we come to know which is which? Some think we can’t know what is good and evil so the best we can do is live by the conventions of our times. Others think it best to let our passions be our guide to whatever we want to do. Others think only revealed religion can give us absolutes. These three positions capture the predominant views of our times. Aquinas holds none of these positions. He argues that reason should be our guide to morality. Not only does he hold that the first principle of natural law, â€Å"do good, avoid evil† is self-evident, he argues that there are other self-evident first principles, such as â€Å"harm no man†. These he says are imprinted in the minds of all by God; I believe other precepts such as â€Å"provide responsibly for your offspring†, â€Å"give to each man his due† and â€Å"seek knowledge† would qualify as precepts that Aquinas thinks all men know. Men (and I use the term generically here and throughout) may act against these precepts out of passion or because ignorance of some fact operative in a situation, but all would agree that such principles are moral truths. Aquinas goes on to say that what he calls primary precepts of natural law are naturally and immediately known by man; he cites the 10 commandments as examples of these types of precepts. These precepts are justified by the primary principles. From the most general principle â€Å"give to each man his due†, from an understanding of what one owes to one’s mother and father, it is clear that one â€Å"should honor one’s father and mother. â€Å"Now this is not to say that one discovers the moral law by discovering these precepts in a deductive manner moving from the most general to the more particular. Rather, it seems that often moral discovery, as the discovery of other general truths, moves from the particular to the universal. That is, an individual could witness or participate in a transaction and quite immediately make the moral judgment that the act is good or bad. That is, for instance, an individual could witness someone honoring or dishonoring his parents and judge the action to be good or bad; from this action and others of the same sort one may come to formulate the â€Å"law† that one should give each man his due. But it is because we already naturally know — in an unexpressed and unformulated way — that one should give each man his due, that we are able to see readily that honoring one’s parents is good. Much in the same way that we, without musical training, can judge certain tones to be off pitch, we have moral â€Å"perceptions† that some actions are good and some bad, without having any explicit training about such kinds of actions. I speak of these as moral â€Å"perceptions† not because they are equivalent to sense perceptions, but because of their immediacy and their unformulated quality; indeed, I believe them to be rational in several important respects, not least because they are cognitive acts and they are in accord with reality. Let me speak now about rationality and the Thomistic claim that â€Å"one should act rationally. † Indeed, one could formulate the first principle of natural law not only in the most basic formula â€Å"do good, avoid evil†; in Thomistic terms, several formulas serve to express the same truth: for Aquinas, the following phrases are synonymous: â€Å"act in accord with nature†; â€Å"act in accord with reason† or â€Å"act rationally†; â€Å"act in accord with virtue†; â€Å"act in accord with the dignity of the human person†; â€Å"act in accord with a well formed conscience†; indeed, â€Å"act in a loving way†, properly understood, serves as well. While it would be of great profit to elaborate how each of these phrases is synonymous with the other, I want to devote most of my efforts here to explaining how â€Å"act in accord with nature† and â€Å"act in accord with reason† are synonymous and worthy guides to moral behavior. First we must try to get as clear as we can what it means to say â€Å"act in accord with reason† or â€Å"act rationally†. In our day, reason often gets a bum rap. This is a fault not of Aristotle or Aquinas but of Descartes and Kant and their followers. Since they retreated into the mind and abandoned the senses and emotions and nature as guides to truth, they made reason seem like something coldly logical, impersonal, abstract and completely devoid of experiential and emotional content. In their view, mathematics and geometry are seen as the quintessential rational acts; to be rational is to operate totally within one’s mind and to be completely unemotional. Another view of rationality that dominates modern times is the view that only that which can be measured scientifically deserves any recognition as objective truth. No truths other than those substantiated by scientific proofs — truths that can be quantified largely in the laboratory — count as truth. No proof other than scientific proofs count as truth; only science and that which approximates to scientific truth is truly rational. Neither view is the view of reason and rationality held by the ancients and medievalists — those who defined the view of natural law I am defending here. The ancients and medievalists did not think rationality was possible without the senses and the emotions for both are tools to reading reality; they provide the intellect with the material needed to make a good judgment. The etymology of the word â€Å"rational† is rooted in the word â€Å"ratio† which means â€Å"measure or â€Å"proportion†. One is being rational when one’s thought and action are measured to, are proportionate with, or when one’s thought and action correspond with reality (which itself is measured or governed by discernable laws; more about this momentarily). The thought that leads to acting in accord with reality is called rational. Now this thought need not be and perhaps only rarely will be the kind of abstract, cold, logical reasoning of a Descartes, Kant, or research scientist. This thought can be intuitive, creative, poetic, inductive, deductive, indeed, whatever human thought can be. It is all called rational thought not because it proceeds by syllogism or because it is subject to certain scientific tests; it is called rational because it corresponds with reality — and this includes all of reality, the spiritual and the transcendental as well as the logically provable and the scientifically measurable reality. Such thought cannot proceed without abundant data from our senses and our emotions. The intellect processes such data and orders it; it determines what values are important in the data and decides on the appropriate response. If one acts rationally, one then acts in accord with the ordering done by the intellect. While the intellect should govern the emotions, it is not a natural law teaching that all rational behavior will be devoid of emotion. Again, the emotions can provide essential data to the intellect. Emotions that are well-habituated may lead one quite spontaneously to respond correctly to situations. One may spontaneously get angry at witnessing some act of injustice and, if one knows one’s emotions to be well-ordered, one could respond quite immediately and correctly to the situation — and even angrily to the situation. Indeed, at times it may be an appropriate response to reality to rant and rave. One doing so, is properly called rational, in spite of our common parlance. This talk of the mind and of rationality as something that is measured to reality suggests, as mentioned above, that reality is a thing that can be grasped. Natural law depends upon such. It rests upon the claim that things have natures and essences that we can know and correspond our actions to. There are many reasons for making this claim. One is the fact that things act in a predictable fashion; when we learn the properties of oil and water, for instance, we can predict certain things about their behavior. The fact that we build bridges which stand, that we make artificial hearts that work, that we put men on the moon, also indicates we are able to measure our thoughts to the external world and to act in accord with it. Moreover, natural law operates on the premise that nature is good; that is, that the way things naturally are is good for them to be; it holds that the operations of things and parts of things contribute to the good of the whole. The wings of different birds are shaped in certain fashions because of the sort of flying that they must do to survive; different digestive systems work in different ways because of what is being digested. Indeed, natural law holds that the natural instincts of natural things are good; they lead them to do what helps those things function well and helps them survive. Since natural things have an order there is said to be a ratio or order to them; not one of which they are conscious but one that is written into their functioning. Natural law holds that we live in a universe of things that have a ratio to them and that we shall get the best out of these things if we act in accord with the ratio or nature that is written into them. Now, man is a natural thing. He, too, has parts and operations and instincts that enable him to function well and to survive. Man differs from other creatures in that he has free will; that is, he can either cooperate with his nature or act against his nature, whereas other natural things have no such freedom. What enables man to be free is his reason, his rationality; he is able to weigh and measure different courses of action and to determine which actions are good or bad. According to natural law, those actions are good which accord with his nature and with the nature of other things. Since man is by nature a rational animal, it is good for him to act in accord with his reason. By acting rationally he is acting in accord with his own nature and with a reality that is also ordered. When he acts rationally, he acts in accord with his own nature and reality and in accord with the nature and reality of other things. Now, let’s get concrete. Let’s talk about acting in accord with the nature of a few specific things. Take tomato plants, for instance. Tomato plants have a certain nature. In order to have good tomato plants one must act towards these plants in accord with their nature; one must water them, give them sunlight and good soil if one wants to produce good tomato plants. Such is acting in accord with nature in respect to tomato plants, such is rational behavior in respect to tomato plants. If one’s tomato plants fail to produce tomatoes, one knows that one is doing something wrong; if one’s tomato plants produce good tomatoes, one knows one is doing something right. Prof. Charlie Rice, whose book Fifty Questions on Natural Law that I understand several of you are reading, speaks of the rationality of putting oil and not molasses in the engine of a car. One needs to act in accord with the nature of things if one wishes them to perform well. So now let us, moving quickly, move to human nature. If a human being wishes to function and perform well, what does his nature require of him? Let us begin with his physical nature. There is a considerable consensus about what makes for physical health and what is conducive to physical health. Those who don’t get sick, who are able to function well in their daily activities, who are not overweight, we call healthy. We know how to produce such individuals. We are regularly and rightly advised to eat well, exercise regularly, and to get plenty of sleep. Those who do so generally flourish physically — because they are acting in accord with nature, with reason, and with reality. Psychological health is also understood to some extent; we know we need friends and rest and interests to sustain our psychological health; that is our nature; that is reality. Nor are we in the dark about what makes for moral health or moral goodness. We recognize the goodness of the various virtues such as self-discipline, reliability, justice and fairness, kindness, truthfulness, loyalty, etc. those who exhibit these qualities we generally recognize to be good — that is morally good — human beings. Parents who have children who display such qualities are rightly proud of them; their â€Å"tomato plants† turned out well. So, in regard to sexual behavior, to sexual moral health, so to speak, what qualifies as acting in accord with nature, with reason? How do we determine what it is? Now, for Aquinas, these are not difficult questions, though, apparently, they are extremely difficult questions for modern times. We are terribly confused about what proper sexual behavior is. College newspapers are filled with news of campuses that are devising codes of moral sexual behavior — codes that are designed primarily to stop or reduce the incidence of date rape on campus. These codes suggest, mandate, require — I am not certain what is the correct word — that in sexual activity neither individual proceed to the next level of sexual activity without obtaining the permission of the other individual. These codes reflect what has been the principle governing sexual behavior in modern times for sometime — whatever one feels comfortable with and whatever one agrees to is morally o. . This is basically what we are teaching to our young people and they are doing much what one would expect given that teaching. As long as it feels good, and they have consented to it, there is no reason for them not to do â€Å"it†. Is this working; is this principle leading to moral health or moral sickness? What can we say about the moral sexual health of our society? What does the fact that 68% of African-American babies are born out of wedlock suggest? The figure is now 22% in the white community and rapidly growing.

Subatomic Particles and the Human Buffer System

Essay-Subatomic Particles There are three different types of subatomic particles. The nucleus of an atom is composed of two different types of particles, protons and neutrons. Protons are positively charged atoms. The weight of a proton is one amu. Protons are located inside the nucleus and cannot move from inside the nucleus. The proton symbol is . Neutrons are also located inside the nucleus and have a neutral charge. Neutrons are also one amu like protons. Neutrons can move from the nucleus of an atom making an atom an isotope. The neutron symbol is .Electrons are located outside the nucleus in energy levels. Electrons have a negative charge and weigh approximately 1/2000th of an amu. The weight is almost insignificant. Electrons can vary in an atom making cations and anions. Cations are a positive charge when an atom loses an electron. Anions are a negative charge when an atom gains an electron. These are the three subatomic particles that make up an atom and their characteristic s. Essay- Buffer System Buffers resist pH fluctuations. A buffer is composed of a weak acid and a weak base. Carbonic acid is the weak acid and bicarbonate is the weak base.When a solution is to acidic the pH is low and there are to many hydrogen ions. The low pH level is caused by to many hydrogen ions. To make a solution neutral you would need to make more acid my combining bicarbonate and hydrogen ions to form carbonic acid. By doing this you are reducing the number of hydrogen ions in a solution. When a solution is to basic the pH is high and the number of hydrogen ions is low. The pH is high because the solution has a low number of hydrogen ions. To make a solution neutral in a basic solution you need to break down carbonic acid increasing the number of hydrogen ions.

SAT for Regular Admissions Deadlines

When's the Last ACT/SAT for Regular Admissions Deadlines SAT / ACT Prep Online Guides and Tips If you have been putting off the ACT/SAT or are hoping to retake one, you need to know when you can take your last test so that your scores will arrive at your schools in time. In other words, when is the very latest you can take the SAT or ACT for your college applications? Read on to find out when you can still take the SAT or ACT- and when you'd be too late. You might be surprised by how little time you have! College Application Deadlines: General Info and Trends Most regular decision college application deadlines are around January 1, though some are earlier in mid- to late December and some are as late as mid-January. I recommend keeping New Year's in mind as the general date your college applications will be due. (Note that if you are applying to a school early action or early decision, your application deadline will likely be much sooner!) The standard date you find out your admission decision is April 1 (though some colleges release results earlier in March). But while admissions decisions are finalized in March, applications are being read and evaluated long before then. Typically, applications are read for the first time in January and maybe February, and decisions are made in February and March. This is why having your entire application submitted by the deadline, including your SAT/ACT scores, is so crucial. In many cases, your application could be read before your parents get around to taking down the holiday decorations ... In order for scores to arrive in time to be considered in January, the last ACT/SAT test dates are usually in December. (For the 2019-20 school year, this is the SAT on December 7 and the ACT on December 14.) December scores usually arrive in time to be considered during the initial application reads in January and February. However, if you take the tests in February or March, your scores won't get to your schools until March or April, which is typically well after your application is read for the first time. (In early 2020, the ACT is on February 8 and the SAT is on March 14.) Since there is no longer a January SAT test date, this means December really is your last chance for the SAT for almost all schools. While a handful of schools do accept the February ACT, these policies aren't the norm. Ideally, you want to finish your SAT/ACT testing before senior year so you can focus on applications exclusively. If you're taking any of the final test dates, you have to make sure you put your colleges down to receive your scores when you're signing up for the last available test. In other words, don't wait to see your scores before you send them, or else it will be too late! If there's a problem with your score reports or they get delayed, sometimes colleges will accept a screenshot or printed version of your test report sent from your guidance counselor as a provisional result. That said, this won't replace an official score report from the College Board or ACT, Inc., which needs to be sent along eventually. Last SAT/ACT Test Dates: Advice for Your College Applications If you're reading this as a junior or younger, aim to have your standardized testing done before senior year, or at the very least by the October ACT/November SAT dates (this means the October 26th ACT and the November 2nd SAT for the 2019-20 school year). This will make the application process less stressful since you'll only have to focus on applications, not testing. Studying for the ACT/SAT while also working on an your applications in December can be a real stressor and might result in subpar applications! Keep in mind that if you're sending SAT/ACT scores from the last possible test date, you're taking a risk. If it's your first test score and it's not within your schools' average score ranges, it won't help your chances of admission. It also won't look good if it's a retake and your score goes down. (While most schools focus on your highest test scores, some require students to send all SAT scores or all ACT scores and will take all scores, high or low, into consideration.) This is why we recommend having your testing done by senior year- including retakes. If you really need to take one of the last possible ACT/SAT dates, plan ahead as much as possible so you have plenty of time to both study and work on your applications. The Latest Possible ACT/SAT Dates for Top Schools In this section, we'll be taking a look at the last possible ACT/SAT dates for top colleges. We'll also show you how to look up this information yourself for any school you're interested in applying to. Schools Whose Final Testing Date Is in December The majority of schools we researched will accept the December ACT and December SAT, but no later SATs or ACTs. If any of your top schools are on this list, do your best to complete your testing as soon as possible! You'll need to have your standardized tests completed by winter break if you're applying to any of these schools! Amherst For regular decision, Amherst requires all materials to be received by January 1. This means you should aim for the December ACT or December SAT at the very latest. Brown According to Brown's website, "Most first-year students choose to apply under our Regular Decision plan, which requires applying by January 2 (11:59 p.m. applicant's local time)." (emphasis mine). Caltech Caltech lists December as its standardized testing deadline, meaning you can take the December ACT or SAT at the latest. Applications are due by January 3 for regular decision. Cornell Everything has to be submitted by January 2 for Regular Admission for Cornell, which means your last-chance test dates for the SAT/ACT are in December. Dartmouth At Dartmouth, because the regular decision deadline is January 2, the last possible SAT/ACT test dates for regular admission are in December. Duke Although Duke's last test date is December for both the ACT and SAT, the school will accept ACT scores from the February test date and consider them as additional scores in your application file. The regular decision deadline is January 2. Georgetown Georgetown's deadline is slightly later in January than those of many other top schools: "Regular Decision applicants should have all application materials postmarked by January 10" (emphasis mine). The December ACT and SAT are still the last test dates whose scores will arrive before the deadline. Harvard There are two regular decision deadlines at Harvard: December 15 (the preferred deadline) and January 1 (the final deadline). Harvard states on its admissions website, "Although it is possible to submit scores from tests taken as late as the December SAT and the February ACT, we recommend that you submit testing as early as possible" (emphasis mine). However, the school also says, "Scores submitted before the end of November will allow us to begin our evaluation process for those submitting applications by December 15." So even though you can submit scores from December tests, the earlier you submit, the better! MIT At MIT, most parts of the application are due by January 1. Therefore, "you must take the required tests on or before the November test date for Early Action or the December test date for Regular Action. These are the latest scores that will reach the Admissions Committee in time for review." Northwestern Since the application deadline for regular decision is January 2, the latest tests you can take for Northwestern are the December ACT or SAT. Princeton As the deadline for regular decision is January 1, "regular decision applicants must complete all SAT testing by the December test date. All ACT testing must be completed by the December test date." Stanford For the regular admission deadline on January 2, Stanford's last test date is in December for both the ACT and SAT. University of Pennsylvania According to Penn's admissions website, the regular decision deadline is January 5, meaning the last test dates accepted are those in December for both the SAT and ACT. Vanderbilt Vanderbilt's website states the following: "For students applying under Early Decision II or Regular Decision (submission deadline January 1), the last opportunity to take the exam is the December administration" (emphasis mine). Washington University in Saint Louis "The last test date accepted will be the December testing," writes the WUSTL website. So at the latest, you can take the December SAT or ACT for Regular Decision (deadline January 2), or the October SAT or ACT for Early Decision (deadline November 1). Williams College You have to take the ACT or SAT by December for it to be added to your file at Williams in time for the January 1 regular decision deadline. These next schools let you take an even later test- the February ACT! Schools That Accept Testing Through February Some top schools have even later testing deadlines and will accept the early February ACT. Again, these schools are in the minority, so do your best to complete your testing much earlier than February of your senior year! Columbia According to the Columbia Admissions FAQ, "Scores for February tests can be provided in time for consideration. Testing taken after February cannot be considered." Note that although the regular application deadline is January 1, Columbia is willing to accept scores from as late as February. University of Chicago UChicago says that it will accept January SAT scores and February ACT scores. However, since there is no longer a January SAT test date (it was replaced by the August date), your last possible SAT test date is actually the one in December. You'll still have the February ACT, though. The deadline for regular decision is January 2. Yale The last testing dates Yale will accept are the December SAT and the February ACT. Applications for regular decision are due by January 2. How to Look Up the Last ACT/SAT Date for Any School We couldn't include the final SAT/ACT date for every single college in the country! Use this guide to learn how to look this info up anywhere you're applying. First, search "[School Name] regular decision deadline" on Google. I'm searching for Wellesley College's last possible SAT and ACT dates. The first link, "Decision Plans and Deadlines," looks promising, so I'll start there. This search should pull up the page on the school's admissions site with regular decision dates and deadlines. The admissions page will typically list the last SAT/ACT dates a school will accept for consideration. For Wellesley, the first link I found led to the following page with info about regular decision dates and deadlines, including for standardized tests: For the regular decision deadline of January 15, Wellesley lists the last possible test dates for the SAT or ACT as "December of your senior year." If you're looking up a school and can't find a deadline page that lists SAT/ACT dates, check its FAQ page- there's often a question there about SAT/ACT testing. Look for questions such as "When is the latest I can take the SAT/ACT?" and "How long does it take for SAT/ACT scores to arrive?" If there's no info about the last ACT/SAT dates on either your school's deadlines page or FAQ page (which is unlikely!), call the admissions office and ask about the last test date you can sign up for if applying regular decision. Key Takeaways: The Last Test Dates for Regular Admissions Most schools have regular decision admissions deadlines on or around January 1. These deadlines vary slightly depending on the school and can be as early as mid-December or as late as mid-January. As a result, usually your absolute last chance to take the SAT or ACT is in December; however, it's advisable to opt for an earlier test date, if possible. If you decide to take the December test, be sure to choose your score recipients as you register for the test. This ensures that your scores will arrive at your schools before the January deadline. While results from a December test should arrive in time, it's best to take the SAT/ACT as early as possible- typically starting in the fall of your junior year. This way you have plenty of time to retake the test should you want to get a higher score. What's Next? Read more about optimizing your ACT and SAT test dates for your senior fall schedule.

A Compare and Contrast Essay on Batman and Iron Man

Today, we can see so many heroes in society. Various types of heroes appear in various cultures and various countries. Heroes give us confidence and we can trust them. I chose two heroes for comparison and compared it based on the cultural aspect and its behavior. The two heroes are Batman and Ironman. In the movie, the image of the hero is very clear. They are strong muscles; beat the bad guys to save the world, they have a girlfriend or a girlfriend. Their health is very good, their health is good. Because Iron Man and Batman are my favorite superheroes, I always wanted to contrast. There are some similarities between Iron Man and Batman, but both fight against the rogues to protect people and cities. They do not have super powers, they use technology and weapons to make their suit. Because everyone at Gotham is afraid of Batman, there are also some differences between Batman and Ironman: Iron Man is a hero, but Batman is a dark hero. Let's first introduce the similarities between Iron Man and Batman, then explain the difference between Batman and Iron Man in detail. After comparing Iron Man and Batman, it is difficult for me to choose who is better. Because I am still in primary school, I have been a Batman for a long time. I have not explained all the differences and similarities between Iron Man and Batman, but if you want to know more about them, try the movie. The movie is really funny. You can choose between Ironman and Batman. For casual movie fans, the idea of ​​comparing Iron Man and Batman seems reasonable given the apparent similarities of both. But trying to compare the two according to a darker question, Iron Man knows that it is not dark, so many people confuse it. However, if you are accustomed to manga books of a specific form or form called Iron Man, this comparison is fair considering how serious the cartoon book Iron Man is compared to the light version in the movie. Let's compare who is a more meditative villain - Iron Man an d Batman

Book review on Song of the Hummingbird Essay Example | Topics and Well Written Essays - 750 words

Book review on Song of the Hummingbird - Essay Example The location is in Mexico, and she wants to see somebody who can act as her confessor. â€Å"Song of the Hummingbird† is a novel by Graciela Limon that was written in 1996, and the main purpose of writing this novel was to tell the ‘actual’ story of the fall of Aztecs where Spaniard and Cortes were the conquerors. One version of the history is told the rulers of the country while its other version is told by an old lady (Hummingbird) of the nation in the form of a confession. The old lady is pretty intelligent and she chooses to make a confession before a confessor and starts telling the story of the cruelties, suppression, and brutality of the rulers as well as the actual tactics that were adopted to convert the inhabitants of the nation to Christianity. Huitzitzilin (Hummingbird) is actually a noble lady and is Aztec by birth. It was her twentieth year of age when the Spanish armies entered their country. She was caught by â€Å"awe caused by those bearded white men†. Later on, just like many other patriots of her nation, the feeling of anger possessed her mind, and led her to believe it to be the â€Å"end of civilization†. A princess is, thus, converted into a concubine (mistress who is sexually exploited by her master). She relates the confession or the historical events to the father who is deeply involved in hearing the story and becomes a source of imparting the actual events of history that are contrary to the incidents that are written in books. Father, Benita Lara, had actually come to take her confession and to convert her whereas she was pretty clever and a lot more intelligent than her contemporaries. She wanted to tell the exact socio-political cruelties that had lingered on her people and the brutality that was thrust upon them by the rulers. So, she chooses an odd way of telling history and, towards the end of the confession, she was able to convey her mind to the
