  • Hypothesis Enzymes - 1,392 words
    Hypothesis Enzymes Hypothesis Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of amino acids to form the active site, or the location on the enzyme where the substrate binds and the reaction takes place. Enzyme and substrate fail to join together if their shapes do not match exactly. This ensures that the enzyme does not participate in the wrong reaction. The enzyme itself is unaffected by the reaction. When the pro ...

  • Peter Mitchell 1920 1992 : Chemiosmotic Hypothesis - 1,118 words
    Peter Mitchell (1920 - 1992) : Chemiosmotic Hypothesis Peter Mitchell's 1961 paper introducing the chemiosmotic hypothesis started a revolution which has echoed beyond bioenergetics to all biology, and shaped our understanding of the fundamental mechanisms of biological energy conservation, ion and metabolite transport, bacterial motility, organelle structure and biosynthesis, membrane structure and function, homeostasis, the evolution of the eukaryote cell, and indeed every aspect of life in which these processes play a role. The Nobel Prize for Chemistry in 1978, awarded to Peter Mitchell as the sole recipient, recognized his predominant contribution towards establishing the validity of th ...

    ... ochrome oxidase involved some fairly heated debates before it finally went to Mrten Wikstrm; and it looks as if the mechanism of ATP synthesis through the F1.F0 ATP-ase is more along the lines envisaged by Paul Boyer than through Peter's earlier proposals. In both these cases, with the benefit of hindsight it looks as if Peter underrated the role of the protein and the subtlety of evolution in designing molecular mechanism. It was part of Peter's charm that, no matter how strongly he held his views, his stance was based on sound principles and experimental results, was always well argued, fair, and devoid of malice. When convinced, he conceded graciously; if his own views prevailed, he w ...

  • The Dustcloud Hypothesis - 318 words
    The Dust-Cloud Hypothesis The universe contains huge clouds made up of very large amounts of dustand gas. About 6,000,000,000 (billion) years ago, one of these clouds began to condense. Gravitation--the pull that all objects in the universe have for one another--pulled the gas and dust particles together. As the dust cloud condensed, it began to spin. It spun faster and faster and flattened as it spun. It became shaped like a pancake that is thick at the centre and thin at the edges. The slowly spinning centre condensed to make the sun. But the outer parts of the pancake, or disk, were spinning too fast to condense in one piece. They broke up into smaller swirls, or eddies, which condensed s ...

  • A Cultural Approach - 964 words
    A Cultural Approach The cultural and developmental aspects of American history in the 17th and 18th centuries are certainly among the most important and influential factors in the shaping of this country's long and storied history. Historiographically speaking, there are undoubtedly thousands upon thousands of different studies and opinions on the most influential cultural strides of early Americans well as the pros and cons that each colonial region developed in shaping America and readying it for the Revolutionary Era. Each of these four studies brings a slightly different and even, at times, conflicting approach to analyzing the cultural and social roots of early America, but each one pro ...

  • A Vogadro Was Born On June 9, 1776 In Turin, Italy He Began His Career In 1796 By Obtaining A Doctorate In Law And Practicing - 596 words
    A vogadro was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for three years after. In 1800, he began to take private lessons in mathematics and physics and decided to make the natural sciences his profession. He was appointed as a demonstrator at the Academy of Turin in1806 and the Professor of Natural Philosophy at the College of Vercelli in 1809, and in 1820, he was appointed the professor of mathematical physics. He was a physics professor but he also experimented in chemistry using mathematics to base most of his findings. Avogadro is well known for his hypothesis known as Avogadro's Law. His law states that a ...

  • Abortion - 1,294 words
    Abortion There are few issues that can cause as many heated and sometimes, irrational, debates than that of abortion. The issue strikes at the very heart of an individual's religious and philosophical beliefs. Does a woman have the right to terminate a pregnancy? Is it moral to do so in any circumstance? Is a fetus a living human being? The debate has raged for nearly thirty years and there does not seem to be any end to the controversy that often results in violence. Irrational individuals who have committed murder want to make their beliefs heard and followed. In response to the question, some people have resulted to using qualifiers: no, abortion is not moral except if the pregnancy is th ...

  • Abortion - 1,138 words
    Abortion Abortion has been one of the topics of hot debate for the last three decades in our nation. Since the Roe v/s Wade decision in 1973, some Americans feel the need to ponder whether aborting fetuses is a moral action. On the one hand, some people feel that abortion should be legal because a woman has a right to choose whether she wants to continue a pregnancy or not. It's her body. On the other hand, some feel that fetuses have no advocates and deserve a right to live, so it is immoral to abandon their rights and kill them. This issue is not only at the center of political debate, but philosophical debate as well. In this paper, I will examine and critique Mary Anne Warren's On the Mo ...

  • Abortion Prochoice Views - 1,417 words
    Abortion - Pro-Choice Views Introduction From 1973 to 1987, over 22 million abortions have been performed. Pro-lifers would call that a terrible waste of human life. True, 22 million lives were taken, but I believe that we are better off without those. Please let me explain in the following report. What is abortion? Webster's dictionary defines abortion as "the expulsion of a nonviable fetus." Abortion might possibly be the most controversial topic right now. I'm sure by now that you've heard of all the different types of abortion. Almost all abortions performed in the US are surgical abortions, where the fetus is removed by suction or other means. (Medication offers another option, to be di ...

    Add Attention Deficit Disorder For centuries children have been grounded, beaten, or even killed for ignoring the rules or not listening to what they're told. In the past it was thought these "bad" kids were the products of bad parenting, bad environment, or simply being stubborn, however it is now known that many of these children may have had Attention Deficit Disorder, or A. D. D., and could've been helped. A. D. D. is a syndrome that affects millions of children and adults in the United States and is a very frustrating and confusing syndrome that often goes undiagnosed. While there is no clear-cut definition of A. D. D., it's known that it's a genetic disorder that affects males more oft ...

    Addiction Treatment Addiction Treatment This study will explore existing research data and reports from various agencies and journals in order to answer the question: does the length of treatment improve the success of people who are addicted to drugs and/or alcohol? I have chosen several scientific journal articles concerning the relationship between the success rate of substance abusing clients and their length of time spent in treatment. Equal numbers of studies, both supporting and not supporting my hypothesis, will be used in order to present an unbiased, objective evaluation. In reality the dependent variable that I am interested in measuring is the success rate of substance abusers, w ...

  • Adlerian Psychotherapy: An Overview Of Theory And Practice - 1,190 words

Although the individual is not always fully aware of their specific goal, through analysis of birth order, repeated coping patterns and earliest memories, the psychotherapist infers the goal as a working hypothesis. The client approaches control of feelings and emotions. First, the client recognizes what kind of feeling he or she is having (angriness, sadness, frustration, etc). Once the client sees and knows the feeling; then he or she will try to imagine or think of something pleasant that had happened to him or her, replacing the bad feeling for a good one. By doing this, the client is in ...

  • Advertising And Media - 1,437 words
    Advertising And Media The evolution of the mass media is very interesting subject of study that presents variations according to different circumstances. One of these is the place where this evolution takes place. Because media as institutions are part of society, are influenced from any particular characteristic that each society has. In the case of Greece, it's really interesting to see how the evolution of a medium like radio, has been affected by the particular characteristics of Greek society and more specifically by Greek politics. The particularity of the Greek case, as Papathanassopoulos points up, is that the Greek state is hyper centralized because of the dictatorial periods that G ...

It suggests that through suggestion, modeling, or by legitimizing killing, homicide numbers increase. In a study taken from 1957 to 1982 by Isaac Ehrlich, the number of executions in 1957 was 65 and the number of murders was 8,060. From 1958 to1960 the execution rate stayed roughly the same, but the murder rate increased (Bender& Leone, 1986, p. 99-100) (Vila & Morris, 1997, p.223). Throughout the remainder of the study the execution rate dropped and the murder rate continued to increase. In 1981 the murder rate was at 22,520 a ...

  • Aging Theories - 1,709 words
    Aging Theories This report outlines the main theories of how the process of aging works. Since researchers have not discovered a universally-accepted theory of aging, the theories discussed are potential explanations of how we age. The likelihood of each hypothesis is considered roughly equal. The different theories discussed focus on the workings of different parts of the body, from the molecular level of DNA mutations and replication, to the organism level of becoming "worn out." Aging is a very complex and gradual process, and its ongoing operation is present to some degree in all individuals. It is a journey to the maturity, as well as to the degeneration of the body. Because aging affec ...
