Antibiotic Lab Report By: Sierra Toll Hour: 6 Title: The effects of antibiotics on the growth of Escherichia Coli Problem: How do antibiotics affect the growth of E coli? Hypothesis: If Penicillin is applied to the bacteria‚ then the zone of inhibition will be larger. Background: The purpose of this lab was to see how effective a certain antibiotic is to kill E coli. The lab tested three antibiotics‚ Penicillin‚ Erythromycin‚ and Neomycin. The zone of inhibition‚ which is the amount of space

¬¬¬¬In this lab‚ we explored the theory of combustion and used it to create and biodiesel. Diesel is a common fuel used to power many large trucks and heavy equipment (such as tractors and backhoes). Diesel fuel is made from crude oil that was formed over millions of years by the decomposition of prehistoric plants and animals. Through the use of an oil well‚ crude oil is pumped out of the ground and transferred (often by large ocean tankers) to oil distillation units. Crude oil contains widely varying

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap
