When finding out unknown bacteria you have to go through several steps to figure out what it could be. I was given unknown bacteria number 28 and asked to run different testing to identify exactly what this bacterium is. I ran 6 test to determine my unknown. These test includes: Gram Stain, SIM, Sucrose, Citrate, MAC, and EMB. Each one of these test are different and they will give a positive or negative feedback which is how we will know which bacterium I have. A gram stain is one of the most…

Rachel Carson, a biologist, was the founder of the modern environmentalism movement during the 1960’s and 70’s. This movement spread quickly throughout the United States. Carson is known today for publishing her very famous book Silent Spring. This book was published during such an important time in history and is significant to this day because it tells us a lot about the environment we live in today. Many people have been fascinated by her book and several other pieces of work. She has…

Being products of evolution, nearly all living things are, in essence, products of their environment. The environment influences which traits are successful and get passed on. Before long, those organisms are directly products of their environment. This phenomenon chiefly occurs when the environment holds all the power over the organism. When it comes to humans, however, we are social animals, we influence and are influenced by those around us. Because of this, humans are not solely products of…

Jonathan Jeschke discusses a rapidly growing scientific discipline known as the four general hypotheses in modern Invasion Ecology. Ecology is defined as the study of interactions between organisms and their natural habitat. Jeschke elaborates using different methods of hypothesis to disclose an unambiguous image of each ‘backbone of science’ as a whole and individually and the ways it is beneficial to us. However, the most important influential invasion hypothesis I believe is Biotic Resistance…

In the article written by Julie Beck entitled “When Are You Really an Adult?” she uses a series of true life accounts to attempt to define when a person becomes an adult and what defines adulthood. She begins with the real life example of Henry David Thoreau and catches the attention of the reader by leading them down the path that she is talking about a current day young man. However, when she reveals she is talking of a young man of years past it is obvious that many different generations…

The U.S. should not allow a free market because of the factors that come along with it. One can look at this in an economic level, spiritual level, and also a personal level. Both articles list many facts that can make one choose their side. For instance, why wouldn 't one want to sell his or her organs? One would be making money and saving a life. However, when making a decision like this it can affect and individual for a long time or even one 's life. Selling one 's organs is not something…

The world has many amazing creations that inhabit our world. Nature is everywhere in our world and everything we have stems from nature. Nature is one of the world’s most pure and beautiful creations. Normally, I admire nature, but do not focus on it. Nature is always there. In my practice, I spent thirty minutes at Norris Reservation trail and took photographs. I learned about myself and about taking care of the world around us. The practice helped me in increasing my reverence of nature, which…

“All animals are equal, but some animals are more equal than others”. A quote by George Orwell, the author of Animal Farm. Anywhere you look or go in life you will find a system in place. It may not be obvious at first, or it may be dominant in that environment, but we have hierarchy wherever we go. This book was written in 1945 and oppression still reigns. Even in first world countries. I won’t even start talking about third world countries. That's 71 years down the way and nothing has changed…

4. Genetic drift is an intriguing concept in genetics that focuses on explaining the random variation in changes of allele frequencies from one generation to the next in populations. The variation comes from sampling error because in many genetic models populations are assumed to be infinitely large, which is seldom the case. A simple mathematical approach to modelling genetic drift is the Wright-Fisher model. In this essay the general principles of the Wright-Fisher model will be explained, and…

Throughout the history of biology and psychology there has been a firm belief of the effects of nature versus nurture. This belief explains that humans have innate traits when they are born but new ones can be developed throughout time. In the book Empire Falls there are many characters that display this change of character but more importantly the books shows how it affects their own and others lives, one such character is Tick Roby. Tick was first introduced to us as a burdened teen, but…
