Bio Lab report

The experiment that we did this week was too find the India ink consumption rate of tetrahymena over certain time periods. The way we did was to add Glutaraldehyde to the tetrahymena to stop them from moving. Then we added India ink to the tetrahymena and let them sit for certain intervals of time. After the period was up we looked at the tetrahymena under the microscope, and counted the number of vacuoles in each cell containing ink. We counted ten different cells for each time. After finding all this we found the mean and the standard deviation for all the different time periods. We found the standard deviation by finding the mean of all the vacuoles at each time
