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…

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…

Births typically occur in spring and summer, although the majority occur in June where the female will have anywhere from one to five cubs with the average being two cubs. The size of the litter, however, does not affect the gestation length…

First there is the One-male and multi-female, this group has one…

Pthirus pubis, also known as pubic lice or crab louse, is an ectoparasite, which is strictly host specific to humans. Pubic lice have three stages: egg, nymph, and adult (CDC, 2017). Pubic lice targets coarse hair at its base and normally remain on its host until it is removed, controlled, or treated. Initially, the female will lay two to three eggs, also known as nits, over the course of twenty-four hours (CDC, 2017). The nits have a whitish in color and have an oval-like structure, with an…

species, it is important that we understand the role pheromones play in sexual selection. Moving forward, future research on this topic needs to focus on the role of pheromones. These non-visual ways of communicating need to be examined further in order to gain a better understanding of the role they play in sexual selection. A future study (with more advanced equipment) could look at the impact pheromones have on the level of sexual attraction between two organisms. Instead of simply recording…
