.... the first eight weeks of pregnancy. This period is called embryogenesis. During the first week after fertilization, which takes place in the Fallopian tube, the embryo starts to cleave once every twenty-four hours (Fig. 1). Until the eight or sixteen cell stage, the individual cells, or blastomeres, are thought to have the potential to form any part of the fetus (Leese, Conaghan, Martin, and Hardy, April 1993). As the blastomeres continue to divide, a solid ball of cells develops to form the morula (Fig. 1). The accumulation of fluid inside the morula, transforms it into a hollow sphere called a blastula, which implants itself into the inner lining of the uterus, the en ....

.... Rev.Djiniynni Gondarra put forward the NT euthanasia law .But was dismissed by the NT Supreme Court. After appealing and with the support of three major party leaders the law was passed. Prime Minister John Howard disapproved with the Law and saying that he has no problem reconciling his views on federalism with his views on life and death by voting to over turn the law. Also Kevin Andrews was strongly not in favour and with Howard's support he introduced a bill overriding the N.T laws. But still in the end the law was still standing. If our leaders are divided we could say that the citizens of Australia would have been divided on this Issue. Maybe a referendum would ha ....

.... of Segregation stated that the members of a paror of homologous chromosomes segregate during meiosis and are distributed to different gametes. This hypothesis can be divided into four main ideas. The first idea is that alternative versions of genes account for variations in inherited characters. Different alleles will create different variations in inherited characters. The sescond idea is that for each character, an organism inherits two genes, one form each parent. So this means that a homolohous loci may have matching alleles, as in the true-breeding plants of Mendel's P generation(parental). If the alleles differ, then there will be F hybrids. The third idea states tha ....

.... medical world. Xentransplantation was the put on the back shelf until the 1960's when scientists started researching why was rejected by the body so quickly. It was not until the last decade that transplantation of animal organs into humans became a realistic goal. Thanks to Jeffery Platt, a professor of experimental surgery at Duke University Medical center who devoted his career to the understanding of how the human immune system recognizes foreign implanted tissue and rejects it. He concluded that the immune system works likes an army with several lines of defense to protect the body from infection by foreign organisms such as bacteria and parasites. This line of defen ....

.... dissonance theory is very closely related to many of the consistency theories. The first of the major consistency theories, the balance theory, was proposed by Fritz Heider (1946, 1958) and was later revised by Theodore Newcomb (1953) (Larson, 1995). Heider and Newcomb's theory was mostly looking at the interaction between two people (interpersonally) and the conflicts that arose between them. When two people have conflicting opinions or tension is felt between another person, it is more likely persuasion will occur. Because if no tension was felt between the two parties, or there were no conflicting opinions there would be no need to persuade each other. If you think ....

.... different. It is also significant to remember that people will easily retain contrasted opinions on these issues because it is from their own ideals and beliefs that their own sets of morals arise. Thus, is it possible for someone who is conservative in regard to abortion to favor active euthanasia? With all aspects considered, it is definitely very possible for one to sanction active euthanasia, and at the same time remain conservative in regards to abortion. It is possible that the dilemmas of birth control and birth selection can extend to the problems of death selection and death control whether by the individual or society. However, the theories of ‘birth’ and ....

.... Administration has classified as a Schedule II controlled substance, in the same category as cocaine, methadone and methamphetamine (Snyderman 1). Both cocaine and Ritalin use the same receptor site in the brain, giving the same "high" and in medical research are used interchangeably. The only difference between cocaine and Ritalin is that cocaine leaves the receptor site quicker than Ritalin, possibly making it more addictive (Snyderman 1). Ritalin is not a drug that is typically sold on the street like cocaine or marijuana. It is a drug that doctors prescribe to help children and adults with hyperactivity and attention problems. But are these trained professionals over p ....

.... was published on the same day as the National Conference in Washington, DC for "HIV infection in women: Setting a New Agenda." The conference included activists, physicians and HIV positive women who used the meeting as a forum to voice their concerns about how best to balance women's own medical needs with those of their infants. Other concerns of activists that were voiced were that they don't want laws, policies or medical care imposed on women merely as "vectors" who may transmit HIV to their infants. The new guidelines recommend that all pregnant women should receive HIV counseling and testing. These guidelines are aimed at helping pregnant women know ....
