Tori Gagnon Creative Writing ENR Mrs. Burton 4/21/16 The Black Death The Black Death was a hopeless disease that broke out in Europe. Nobody was prepared for what was about to come‚ and the fight for life was crucial while the fight to dodge the scent of the dead bodies on the street was inevitable. Millions of people perished‚ and ⅓ of Europe’s population had met their demise. (Black Death) It was 1347 and a calamity was brought to the Italians. Not only was disease coming‚ but surrounding natives

that the strength of the bacteria could be reduced by injection of soil bacteria. Research also revealed that the intestinal infections such as cholera can also be reduced. Infections were relatively lower in persons that are administered cholera bacillus. Several antibiotics were also found globally. Before the 20th century‚ there was high mortality rate because of the infections developing from wounds. People were forced into war and in the process gained infection by open wounds. Bacteria enter

GMOs What is a GMO? GMO stands for genetically modified organism. It can be argued that genetically modified organisms have been around as long as humans were using agriculture as a food source. By definition‚ an organism that has been changed genetically by any source that does not occur naturally is a GMO. Any farmer could cross two plants to create a more beneficial crop. Since their creation‚ GMOs have been used for scientific research and midicinal purposes. In 1953‚ the discovery of how DNA

Plus‚ it is unethical some of the things that they to animals like a hairless chicken that is just unethical‚ plus it is unhealthy for humans to eat because of some of the chemicals they put in the food like Bt Bacillus tburiniensis toxin which is a pesticide which. There are also problems with Genetically Modified Food they transfer genes form an animal to a plant and if you have a fish allergy if they transfer the genes of the fish to a plant you can have an

First‚ There is a wide range of types of biochemical weapons. Biochemical weapons can be viruses‚ bacteria‚ and even toxins. One of the most common biological weapons include anthrax‚ a disease of humans and animals‚ instigated by the bacterium Bacillus anthracis‚ a facultative‚ gram-negative‚ nonmotile‚ anaerobic‚ and spore creating organism. Another highly used biological weapon includes smallpox. The smallpox (variola) virus is the most considerable of the animal viruses. The virus particles

Transcription The Central Dogma RNA Polymerase Ribosome DNA transcription replication RNA translation Protein One gene encodes one protein? (Beadle and Tatum‚ 1941) • • • Cellular machinery is largely made up of proteins. Proteins are made up of chains or sequences of amino acids. The sequence of these amino acids are "encoded" in the cell’s DNA. DNA is transcribed into RNA‚ which is then translated into protein. When one gene is mutated‚ one protein is affected (usually

The Differences and Similarities of Pneumonia and Tuberculosis Pneumonia and tuberculosis have been plaguing the citizens of the world for centuries causing millions of deaths. This occurred until the creation and use of antibiotics become more widely available. These two respiratory infections have many differences‚ which include their etiology‚ incidence and prevalence‚ and many similarities in their objective and subject indicators‚ medical interventions‚ course‚ rehabilitation and effects

occurred that day. Now‚ if that isn ’t enough to cope with‚ in creeps the specter of bio-terrorism. Biological weapons are devices intended to deliberately disseminate disease producing organisms or toxins in food‚ water‚ by insect‚ or as an aerosol. Bacillus anthracis‚ the organism that causes anthrax‚ has been bandied about the media and the American public has been saturated by stories of possible cases and fatalities. One agent not often discussed but every bit as horrifying as anthrax is smallpox
