Effectiveness of Garlic in Fighting Bacteria Introduction This experiment determined whether garlic was effective in fighting bacteria. This project interested me because garlic is traditionally used in medicine and is known to combat bacteria. Hypothesis If bacteria is exposed to garlic‚ then the garlic will to abolish the Escherichia coli‚ because the Escherichia coli (E. coli) is usually a weak bacteria. Procedure Have three petri dishes prepared with blood agar‚ and three test tubes

Imagine being alive in the 1960’s. Everything you see in today’s world compared to the 1960’s would be dramatically different. What would you do if you saw a black man being beaten to near death? Would you stand there and watch‚ call for help‚ encourage it? Some of the things in the 1960’s haven’t changed in today’s world. They just simply are not as bad as it used to be. Attitudes in race in the past and now have changed dramatically in perspective. Compared to today and the past there are way more

In the article‚“ What We Really Miss About 1950’s‚” Stephanie Coontz states that “In a poll by the Knight-Ridder news agency‚ more Americans chose the 1950’s than any single decade as the best time for children to grow up.” However‚ Coontz has her own view of the 1950s. Using strong and logical facts‚ she informs the audience of her own opinions about this decade. Although the nostalgia of the 1950s is vastly strong in some people‚ some fail to notice the negativity and reality of it. Coontz does

Biochemical tests are a series of tests used to identify certain bacterium The various tests that are used in this lab are the catalase test‚ oxidase test‚ blood hemolytic test‚ MSA‚ blood agar‚ and PEA/ab sens test. A known Gram positive coccus bacteria will be used alongside an isolated Gram positive unknown bacteria for comparison to aid in the ability

Sampling of Gram-Positive Bacteria and Antibiotic Resistance Resting We thought it would be interesting to find out the different bacteria that grow on things we use on a daily basis and the level of antibiotic resistance that those bacteria have. We chose to swab the toilet seat in the MATC women’s bathroom and the ATM machine in the commons area on campus. We were certain the ATM would be dirtier than the toilet seat since the bathrooms get cleaned every day. The first step we took in testing

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive
