Question: What antibiotics work best in preventing E. coli k12 from growing; amoxicillin‚ ampicillin‚ or ciprofloxacin? Hypothesis: If ciprofloxacin‚ an antibiotic‚ is added to petri dishes covered in live bacteria and left to sit for four to six days in an incubator at 37 degrees Celsius‚ then the petri dishes containing ciprofloxacin will have the largest zone of inhibition out of all of the other antibiotics tested because research shows that ciprofloxacin in one of the strongest antibiotic currently

cause harm‚ society benefits from microorganisms in many ways. Microorganisms are necessary for the production of antibiotics‚ vitamins‚ vaccines and food such as bread and cheese. Dues to its important role in society the study of microorganisms‚ Microbiology‚ has become widespread. Microorganisms collected for study can be grown and visualized in both liquid and solid growth media. The purpose of the media is to provide all of the necessary nutrients for microorganisms to live and reproduce. Although

This project’s purpose is to find the effects of UV light on Staphylococcus epidermidis‚ furthermore recognized as staph infection. Staph infection is an infection usually acquired on the skin that can promote fever‚ nausea‚ pain‚ boils‚ and can lead to MRSA‚ which can lead to death. Because there is no cure for staph infection‚ this experiment called for research on clinical trials. A clinical trial was established that used blue light therapy to delay and kill the growth of staph infection. Coincidentally

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease.
