Becca Harris Writing 101 Position Paper Eliminating Genetically Modified Food at PLU What comes to mind when reading the words genetic modification or Bacillus thurigiensis (abbreviated Bt)? I envision laboratories and science experiments‚ when in reality these words are related to the food we eat every day. What most Americans do not know is the threat that genetically modified food presents to our communities. PLU should do everything in its power to ensure that its students and faculty

DIPTHERIA Diphtheria is an infectious disease caused by the bacterium corynebacterium diphtheria. This disease affects the mucous membranes of the respiratory tract and can also affect the skin (cutaneous diphtheria)‚ including the lining tissues in the ear‚ eye‚ and genital areas. Diphtheria was discovered in the 1880s‚ it was the leading cause of children’s death in many parts of the world‚ it was also known as “The Strangling Angel of Children”. Although diphtheria affects younger children

Explaining Bacteria Alexandra Solorzano 1E “ Hey Alex. Could you help your cousin with his homework?” “Okay‚ but I don’t understand what could be hard about fifth grade homework. Anyways‚ what are you learning about George?” “Well today my teacher started to talk about these things called Blackmeria? Or what is backferium?” “Umm I think you mean bacteria?” “Yeah! That’s it!” “Then I guess it’s your lucky day because right now in STT I’m in Cell Biology and we started to look into Bacteria

the term “cell”. 1632-1723 Anton van Leeuwenhoek credited with having observed the first bacteria. 1828-1898 Ferdinand Cohn developed the first classification scheme based on bacteria shape. Cohn detailed and described the life cycle of Bacillus. Cohn’s Classification System: Sphaerobacteria are spherically shaped. Microbacteria are rod shaped Desmobacteria are filamentous Spirobacteria are spiral shaped 1822-1895 Louis Pasteur Defined pasteurization

standard method of identifying an unknown microorganism relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The focus of this paper will be on the description of the just one of the three bacteria and some of its effects on humans. The first test

Enzymes are globular proteins that are synthesized by the ribosomes in a cell. They act as catalysts during biological reactions; therefore‚ enzymes are able to speed up these reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed
