Introduction Our world is composed of many bacteria that can either help or destroy us. Therefore, its’s imperative to learn and study them. The purpose of the lab was to put into action the methods learned in the laboratory to determine our unknown bacteria. Bacteria can have different features, shapes, and or arrangements that help microbiologist differentiate them. Bacteria can be classified as Gram positive or negative (difference in cell wall), with the help of the Gam stain (“Gram…

While reading the book Genome by Matt Ridley, I started to hone in on some of the key topics and main ideas to take away from this novel. It was a very interesting read that introduced new ideas to me. Many of the ideas in the book applied directly to our Biology class. Some topics that were covered in lecture can be directly applied to the book. Matt Ridley talks about many important things in his novel; however, I feel as if the chapters of life, species, and environment are the most…

In 1971 a gene-splicing experiment done by Paul Berg resulted in the first man-made recombinant DNA. Berg, however, did not continue with the next step of introducing recombinant DNA into another organism. The next step in continuing this process would be the insertion of the recombinant DNA into a bacteria, which was done in 1972 by Herbert Boyer, in collaboration with Stanley Cohen. The limitations of recombination size of genes and the ability…

into using even more toxic herbicides. Under such circumstances, GMOs crops need more and more herbicides to remain ‘herbicide tolerant’. GM crops can reduce bio-diversity or even obliterate birds, insects, amphibians, marine ecosystems, and soil organism. One of the deleterious results is water resources pollution. Certainly, we know the importance of having enough pure water, because it gives life to every creature on our planet, including human…

For the next 2 weeks the copepods would get checked on once a week using a microscope to see which ones’ survived based on movement. It was important to carefully record what plate each survivor was in and whether they were male or female. The organisms were only fed twice during the first trail which was during the set up and on wellness check #2. .5mL of fresh water algae was placed in each well of all the plates. After the second week a new trial was to be held. The…

Animal testing is used for many things. It may be used for testing medical products and just the everyday makeup that women feel the need for. Animals are also used for determining the level of toxicity of medications and checking for the safety of medications for humans. (Should) What if there was a drug that could cure cancer and we did not know if it was safe for humans to take. As mankind we would want to test the new drug on something that has a similar genetic makeup to humans just to make…

Lynn Margulis was born March 5th, 1938 into a Jewish family in Chicago. She attended Hyde Park Academy High School where she was seen as a bad student. She attended and graduated from the University of Chicago in 1957. She continued her education at the University of Wisconsin at Madison earning a master's degree in zoology, and her Ph.D in genetics from University of California, Berkeley in 1965. In between her undergraduate and graduate studies she met Carl Sagan and they married soon after.…

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…

From the moment we come into this world and take our very first breath, all we’re doing is trying to survive. People survive in other ways such as these: in The Hunger Games, by Suzanne Collins, Peeta Mellark has to use his cake decorating skills and make himself blend in with the mud he’s laying in, in order to escape the other contestants to survive the games. In Ender’s Game, by Orson Scott Card, Ender Wiggin has to go through increasingly difficult games and also has to fight off the buggers…

We know what life is. However, we do not know where life came from. Many extraordinary and intellectual people have come up with the most reasonable theories of how “life” came to be. From life being found on different planets, to life being found intriguing places of our very Earth. The Primordial Soup Hypothesis was a theory created by Alexander Oparin and Haldane in 1920. This theory stated that life started from a body of water and amino acids. The beginning of life began as…
