Every year between 700 and 800 adolescents ages 11 - 17 undergo a type of organ transplant.But before they must go through this surgery, they are the ones making the decision to go ahead with it.One example of this poor policy is Courtney Montgomery, who had been battling heart problems her whole life.She refused to undergo a heart transplant to save her life, as a result of past transplants which were temporally and didn’t remove the problem, she had given up hope.Believing she made the right…

Ever since man became self-aware he has wondered how he came into being. As years passed, many philosophers suggested theories, oscillating between superstition and truth, with some theories becoming more popular than others. Charles Darwin, a British naturalist, recorded perhaps the most popular theory—evolution. Believers of this theory declare that the earth is incredibly old, and that life arose from nothing; eventually, man evolved from apes, essentially a glorified animal. As unbelievable…

There are many factors which do affect the growth of nails, but five main important aspects are, age, location on body, hormones, cutting and health. One of the big aspects of the growth of nails would have to be Age, considering we get older every year. Infant nails tend to grow slower than adult nails, although, young children nails grow faster than that of an adult. The Location of the nail depends on the growth, in saying that, fingernails grow much faster than toenails, the difference in…

Adnane Harbouche Developmental Psychology Februrary 6, 2015 Critical Thinking Paper 1 DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a persons body has the same DNA. Most DNA is located in the cell nucleus ( where it is called nuclear DNA) but a small amount of DNA can also be found in the mitochondria (where it is called Mitochondria DNA or mtDNA). The information in DNA is stored as a code made up of four…

Survival of the fittest is basically an organism being better fit for an environment than the other. The traditional view on life is very simple, God created us and we were put here for a “reason”. Darwin’s theory of Natural Selection caused conflict between traditional views because it offered a new explanation other than “God” as to why we are here today. Three main challenges Darwin’s theory of Natural selection faces concerning traditional views is the challenge to biblical literalism,…

Abstract: This paper explores and examines how migration affects a population, and how it affects the frequency or change of alleles in a population. It is asked, “How does migration affect heterozygosity in a population?” I predicted that migration increases heterozygosity in isolated populations. To explore and test out this hypothesis the moth program in the “PopGenLab” was used to carry out the experiment. What was found that migration did keep population high and kept…

In chapter 3 of “Why Evolution Is True” by Jerry A. Coyne, he talks about remnants such as vestiges, embryos, and a bad design in which he describes manuscripts called palimpsests organisms of evolutionary history. In evolution, a feature of a specie that was an adaptation in its ancestor but lost its usefulness are called vestiges. These no longer perform the function from when they first evolved because those parts may have been import to their ancestors but not to them. The author states, “In…

Natural selection is very important in the addition of adaptations to bring forth more able and stronger individuals that can survive in their harsh environment. Selection can make some organisms deadlier, like the Asian giant hornet, or can make other organisms better at finding food in hard to reach areas, such as woodpeckers with thicker skulls. Each of these adaptations are unique to these organisms because these adaptations allow them to live in their unique niches. For natural selection to…

Critics have argued that new technologies such as DNA testing allow for the potential development of new forms of eugenics. What might these forms include? What are the potential dangers involved with these new technologies? It is undeniable that any method that intends to maintain the “good genes” in society would not only spark an extended array of ethical concerns but could also backfire in several ways. Human genetics has been the topic of several debates for an extended period of time,…

In some populations, alleles can be lost due to random events. Genetic drift reduces allele frequencies in smaller population, therefore, decrease genetic variation. It can eliminate alleles at a faster rate in smaller population until they become fixed in the population. On the other hand, alleles in a large population rarely become fixed by genetic drift. This indicates that genetic drift has a greater effect on a smaller population by getting rid of alleles at a faster rate. Genetic variation…
