Karlo Natonton Biology Lab 104-56 Lab 6: Cell Membranes Experiment 1: Discussion In experiment 1, we tested the effects of sodium chloride on the hemolysis of red blood cells. Our null hypothesis was that there is no effect of sodium chloride on the hemolysis of red blood cells. Our alternate hypothesis stated that when sodium chloride was added to a red blood cell, the hemolysis of the red blood cell would be affected and absorbance numbers would increase because the added sodium chloride would make the outside of the cell hypertonic causing water to leave the cell. One can conclude from our results, that our hypothesis was correct with one exception. As the concentration of sodium chloride added to the red blood cell increased, so did the absorbance numbers. The only exception to our hypothesis was the absorbance reading for the RBC’s with 0.10M of sodium chloride. The absorbance readings were rising, but for the 0.10M sample the reading went down. Every reading after the 0.10M sample rose significantly. By looking at our graph that shows the average absorbance of sheep
