“Describe the role of genes and hormones in gender development” Biological sex is determined by chromosomes in your genes. At prenatal development‚ only a few weeks after conception‚ there is no notable difference between male and female structure until the Gonadal Ridges‚ the structure which develops either female or male sex organs‚ grows to determine the sex of the baby. All prenatal babies have genitalia that appears distinctly feminine until at three months‚ hormones- testosterone if the

article An On/Off Switch For Genes written by Jim Kozubek‚ he talks about how doctors are looking at ways to have genes treat different hereditary illnesses. He explains that the gene therapy’s history is not always easy because scientist cannot control where the new gene is inserted. This then causes problems because they need a specific gene to be placed in a certain spot to be read and activated. The started experimenting with the idea of taking a therapeutic gene and combining it with an on/off

the bible. Evolution is believed to have merged via Charles Darwin’s evolutionary theory On the Origin of Species by Means of Natural Selection that suggests all species are interconnected through natural selection‚ but does not consider that the similarities between species are not a result of evolution but the result of an all-powerful creator‚ God. The theory behind Creationism is that all animals and humans were created within a 6-day period by an intelligent designer. The main argument placed against

Gene Editing Human Embryos While very controversial‚ the fact of the matter is that gene editing on human embryos has happened‚ legally or otherwise. Many people oppose this form of experiments‚ and believe that it is not good for the human race. In theory‚ gene editing could give us the ability to remove certain genes and replace them with genes that could serve the same purpose but in a more efficient manner. While gene editing is not a new process‚ it is not an experiment that has been performed

Its primary feature is insufficient blood supply to the heart itself. The two major clinical forms of CHD are heart attack and angina. In a heart attack the insufficient blood flow is sudden and extreme. In angina the episodes of restricted flow are temporary and usually much less dangerous. The common underlying problem in the various forms of CHD is atherosclerosis‚ a complex process that affects the vessels supplying blood to the heart‚ the coronary arteries. In atherosclerosis‚ build-ups called
