The underlying reason that we as humans cannot follow the advice of Jesus of Nazareth is that we are selfish. What this quote is saying is that what ever action or item you would want to get from someone you should return something of equal value. Having that sense of equal reciprocity is against human nature. Throughout the history of human evolution, it is the selfish ones that survive (Dawkins 2006) . Selfishness goes along with competition with both starting very early in our evolutionary…

Cloning may be considered an extremely taboo topic to talk about. This is because of having fear in the unknown. What many people do not understand about the topic of cloning is it is not a perfected science. Cloning has so much potential to do well and help our society if people would just allow it to blossom into more of a perfected science. If people would just allow it to do so, and not base its future off of the unsuccessful experiments that it had it had in its beginning, then we could…

Reproduction In this essay I will attempt to explain the key events in human reproduction and explain the male and female reproductive systems. Both males and females require fully functioning reproductive systems in order to conceive naturally, I will first begin by explaining the male reproductive system, the testes are cradled within a ‘bag’ of skin called the scrotum, their two functions are to produce sperm cells and sex hormones. Next, the vas deferens. Sperm passes through the vas…

The basic principles are simple; the X-sperm contains more DNA than the Y-sperm. Although this difference is small, it is possible to measure DNA content of individual sperm with sufficient accuracy to distinguish between X- and Y-sperm with about 90% accuracy for 50% of the sperm. Therefore, about half of the sperm are discarded as unsexable. The DNA content of sperm is determined using a fluorescing dye, Hoechst 33342 that readily penetrates the sperm cell membrane and binds to the DNA…

evolved to have complete autonomy with whom we reproduce with, especially how that choice relies heavily with females. The captious nature of females makes sense in a system where males are indiscriminate and eager to spread their genes. The cost of reproduction weighs more heavily on the female as she invests the most time during the development of the offspring. She…

Abortion is a very touchy subject to a lot of people. Sometimes you can't even say the word "abortion" without getting disgusted looks from the people around you or getting a lecture about why it's a good thing. Abortion is not a good thing. Why should an innocent life be taken without even having the ability to defend itself? Why should a living thing be told that it doesn't have feelings or that it doesn't matter? Why should a baby not have the chance to live simply because of the poor choices…

Mockingbirds are so good at imitating sounds that acoustical analysis could not tell the difference between the original song or the mockingbird (Wild Birds unlimited). Mocking birds will be the main subject for this paper. This research paper will cover the basics for mockingbirds, vocalizations of the mockingbirds, and interactions with humans and other mockingbirds. The first topic is the basics including habitat, nesting, and feeding. Mockingbirds have nearly disappeared on the East Coast…

Drosophila melanogaster has been studied in genetic research laboratories for almost a century. Because the fruit fly has a short lifespan, a simple genome, and is easily made to reproduce in captivity it is a prime candidate for genetic research. (Patterson, et al., 1943) The major behavioral response noted in the fruit flies is that they tended to group together in clusters, as opposed to venturing off on their own into different sectors. D. melanogaster are attracted to food and will mate…

Who really owns our bodies? Is it us, our parents, the government, the state, or even a higher power? These questions spark a fair amount of discussion throughout our country. Specifically who has the power to choose if you can have children. When people have trouble with this there is a simple answer: Go to a sperm bank or adopt children. People that want the actual experience of being pregnant will most likely choose to go a sperm bank and get it surgically implanted. The big question is: Is…
