Do Antibiotics Affect Yeast Cells?
Biology 1401 Section B
Abstract
Saccharomyces cerevesiae (yeast cells” are a contributing factor to many different things, making them highly important. The two instruments that supplied the most to the experiment were they hemocytometer and the compound microscope. The hemocytometer was used to secure the yeast cells to be able to place them under the microscope. The microscope’s main purpose was to count all the cells. Culture A had no antibiotics; on the other hand, culture B did have antibiotics. The following steps were to acquire the t-statistic, but first we had to acquire the calculations variance, standard deviation, standard error, and the t-statistic. After the t-statistic I found all that was left to acquire were the degrees of freedom and check where or not the null hypothesis was accepted or rejected. After all what determined the probability level was 2.14 and the t-statistic was 2.53 so our hypothesis was rejected. Introduction

Saccharomyces cerevesiae in simpler terms are yeast cells. Yeast is used as a contributing factor to many things, but one of its biggest purposes is to release carbon dioxide (CO2) from bread as well as alcohol. Because after it is released the bread begins to grow, and for the alcohol it makes it foam. For an extraordinary baking procedure, a vast amount of the time yeast cells are going to be involved to contribute to the baking or brewing process. This experiment is done to see if antibiotics provided to the yeast cells stimulate the reproduction of more cells in which bakeries and brewers can get their hands on more yeast then is normally produced. The conclusion to the experiment shows that we accepted the null hypothesis. This determined that the antibiotics had no effect on the yeast cells. Materials and Methods

Out of all the instruments we used the main two instruments that contributed the vast majority to the experiment were the hemocytometer and the compound dissecting...
