At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and

Genetically Modified Organisms Genetically modified Organisms (GMOs) has become a popular topic nationwide. The argument of whether it is ethical to use biotechnology to develop crops has been debated back and forth. However‚ GMOs have been proven time and time again that they can increase food production‚ lower costs‚ and decrease damage on the environment. The increased use of pesticides and fertilizers on plants over the years have made a big impact on the environment. These harmful chemicals

“What is Man? Man is a noisome bacillus whom Our Heavenly Father created because he was disappointed in the monkey.” (Mark Twain). Evolution is a very confusing and complex topic. There is so many different thoughts‚ sides and beliefs when it come to evolution. One main belief of evolution is natural evolution‚ ¨that is which the Earth’s species have changed and diversified through time under the influence of natural selection.¨ (www.dictionary

are all kinds of ways that minimal organisms can be useful. One‚ is in the field of agricultural‚ scientist can create new species of crops that can be less prone to drought and pests. “No insecticidal sprays needed on crops that have insecticidal Bacillus thuringiensis (Bt)-toxin genes engineered into them” (Heaf). This is amazing to me. In the end food costs could possibly go down and we would have products that did not have to use pesticides. Also this can be useful in supplying third world countries

People should know what is in the food they eat today. The package should tell us the things they put in these Genetically Modified Organisms or GMOs for short. They should do this because: we do not know what harmful things are in the foods‚ the side effects it has on other foods too‚ and no real testing has been done to prove these foods are even okay for us to eat. These foods should have labels because we do not know what they contain in them. The company that produces GMOs do not put what

The Black Plague was one of the worst pandemics of Europe affecting one-third of the population. Caused by the bacillus Yersinia Pestis‚ the epidemic was carried through fleas and rats that accompanied Genoese ships. The first known outbreak in Europe started in 1346 and swept from the Mongol Empire to southern France and Spain. Street conditions and warm weather were ideal for the spread and made people more susceptible to the disease. Many physicians tried to come up with ways to prevent the disease

Currently‚ 800 million people suffer from the nutritional deficiencies‚ with 40‚000 dying each day of malnutrition‚ half of them children. There is much disagreement about the causes of such hunger. Some argue that food shortages arise from inequities in the distribution and that the dire poor simply cannot afford food. Others regard food shortages as evidence that the world is overpopulated that the human species has exceeded the carrying capacity of the planet. Whatever the social and demographic

A tuberculosis infection outside of the lungs is called extrapulmonary tuberculosis. In these instances‚ the kidney and bones are more commonly prone to infection. In the kidney‚ tuberculosis proposes little to no symptoms‚ but may destroy part of
