The Variation of Yeast Cells When Adding an Antibiotic Biology 1401- A October 21‚ 2013 Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was

1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill
