Having none of these characteristics viruses cannot be considered a living cell because they do not metabolize, respond to stimuli or reproduce on their own. They have to infect a living cell by entering a l host to reproduce more of its self....   [tags: Organisms, Structure] 799 words

Charles Darwing and The Theory of Evolution - ... In October 1825 Darwin went to Edinburgh University where his grandfather studied to study medicine with a view to becoming a physician. He soon realized that he does not like the study of medicine and could not bear the sight of blood or suffering. So here changed schools and went to Cambridge to become a clergyman. Then he soon noticed he would like to be a naturalist. His theory of evolution by natural selection is what he is best known for today and is now the unifying theory of life sciences explained where all of the mindbogglingly heterogeneous kinds of living things came from and how they became exquisitely adapted to their particular environments....   [tags: biology, galapagos, natural selection]

Do You Choose to be Homosexual? - Do You Choose to be Homosexual. Is it possible for one to choose his or her sexual orientation. Is one's sexual orientation something that can be changed, or is it a fixed attraction. These are a few questions, among many others that have been raised by researchers and religious organizations, as well as everyday people. Particularly, over the last decade there have been various debates over whether sexual orientation is based on genetic factors or whether it is a choice. Most researchers find that homosexuality, like many others psychological conditions, is due to a combination of social, biological, or psychological factors (1)....   [tags: Biology Essays Research Papers]

Biology: What is Speciation? - ... In this example of the giraffes, Darwin suggests that variation was a result of preexisting genetic differences among the giraffes. While this other biologist Jean-Baptiste Lamarck, believed that evolution occurred by the inheritance of acquired characteristics. He believed that the giraffe ancestor lengthened its neck by stretching to reach tree leaves, and then passed the change to the offspring. However, Darwin believed that some giraffes were just born with longer necks due to genetic differences....   [tags: charles darwin, natural selection] 859 words

The Excretory System - The role of the liver is to filter toxins and remove them from the body in the form of nitrogenous waste. Nitrogenous waste is ammonia, urea and uric acid. In the human body only ammonia and urea are produced and the liver quickly changes the harmful ammonia into the tolerable urea for excretion from the body. Ammonia is toxic to humans in high concentrations (see Table 1). Ammonia is the by-product of protein being broken down. Ammonia is formed by the breakdown of amino acids taken from excess proteins....   [tags: biology, anatomy]

Physical Anthropology: The Link between Human Nature - Physical anthropology “is in large part, human biology seen from an evolutionary perspective” (Jurmaln, Kilgore & Trevathan, 2011). By this statement, I believe the authors mean that physical anthropology studies human biology with an evolutionary viewpoint rather than a scientific or medical viewpoint. Anthropology, as a broader science, is concerned with and studies human culture and the evolutionary aspects of human biology. Since culture affects human beings and human beings affect culture, the two are intertwined, and it therefore, makes sense to study them together....   [tags: anthropology, human biology, genetcs]

Breeding Habits of Water Birds - Chapter 1. INTRODUCTION Many species aggregate for feeding, roosting and nesting activities, which are prevalent among water birds (Weins, 1992). Why animals form breeding colonies is a major unresolved question in evolutionary biology. The topic continues to stir lively debate (Danchin & Wagner 1997, Tella et al., 1998) and has been the focus of long term studies (Hoogland 1995; Brown & Brown 1996; Danchin et al. 1998). One of the principal issues has been whether colonies form due to limited breeding habitat; with animals forced into nesting aggregations at a nest cost, or result from social benefits of clustering (Food finding, reduced predation; Lack 1968; Alexander 1974; Hoogland & Sh...   [tags: Biology ] 976 words

The Effect of Cholesterol on Membrane Fluidity - The cell plasma membrane, a bilayer structure composed mainly of phospholipids, is characterized by its fluidity. Membrane fluidity, as well as being affected by lipid and protein composition and temperature (Purdy et al. 2005), is regulated by its cholesterol concentration (Harby 2001, McLaurin 2002). Cholesterol is a special type of lipid, known as a steroid, formed by a polar OH headgroup and a single hydrocarbon tail (Wikipedia 2005, Diwan 2005). Like its fellow membrane lipids, cholesterol arranges itself in the same direction; its polar head is lined up with the polar headgroups of the phospholipid molecules (Spurger 2002)....   [tags: Biology] 981 words

Evolution: More Than One Level - Evolution: More Than One Level The evolution of art mimics biological evolution. For this reason art history and biology are comparable in many ways. Works of art are stories. Each work of art relates to and influences other stories, or pieces of art. Ernst Mayr uses the phrase "descent with variance" throughout his book to describe biological evolution. Art behaves similarly. In addition, like biological evolution there are serious ramifications for the production of art. Because it is possible to view art from an evolutionary perspective it is also possible to look at evolution from an artistic perspective....   [tags: Science Art Biology Essays]
