tics Antibiotics Several scientists around the beginning of the 20th Century discovered substances that were toxic to bacteria yet not to the human cell. But it wasn’t until Sir Alexander Flemings own discovery in 1928 that everyone took notice. While washing his equipment‚ Sir Fleming noticed a bit of mold attacking a patch of bacteria. It’s frightening to consider how many more people would have died in the 20th Century if Sir Fleming did not have good eyes. Today‚ some complain that

Food Contamination Definition Food contamination refers to foods that are spoiled or tainted because they either contain microorganisms‚ such as bacteria or parasites‚ or toxic substances that make them unfit for consumption. Food contamination is a serious issue because it results in foodborne diseases. Hence‚ awareness of potential sources of food contamination is an important component of good nutrition. Food contamination refers to the presence in food of harmful chemicals and microorganisms

of an improvement that has been made in the medical branch of science is the invention of antibiotics. An antibiotic is a substance produced by one organism that can destroy another. The term literally means “against life.” One of the earliest discovered and widely used antibiotics is Penicillin. Penicillin is collected from the Penicillium mold. Alexander Fleming is known for discovering this antibiotic. In 1901‚ he went to St. Mary Hospital to study medicine. In 1914‚ during World War I‚

Antibiotic Resistant Bacteria A better understanding of the use of antibiotics would help prevent the reality of antibiotic resistant bacteria evolving to the point of human extinction. Antibiotic resistance is a natural process‚ stronger bacteria survive and multiply. Even though antibiotic resistance is a natural process‚ it happens faster when antibiotics are used irresponsibly. Through use of media‚ personal responsibility and research‚ our species could help deter further antibiotic resistance

30 February 2014 Antibiotic Resistant Bacteria: What is it‚ how to prevent it and who it affects? In the United States alone‚ about 23‚000 people die from antibiotic resistant infections yearly. It is also one of the top 15 most dangerous illnesses in the country (United States House of Representatives). Antibiotic resistance is when bacteria develops a different response to an antibiotic that is its ancestor bacteria. Slight changes in bacteria enable the antibiotic to work and successfully

Describing Trace Decay Theory of Forgetting * Trace decay theory can be applied to explain forgetting from both STM and LTM. * It is based on the idea that information creates a neurological trace in the brain‚ known as an engram‚ when it is encoded. This means a change has occurred in the structure of the brain. * Hebb (1949) proposed that whilst learning is first taking place‚ the engram is very fragile and liable to disruption. It grows stronger and less likely to be destroyed the
