The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body.

Individual Project Unit 2 Experiments In this individual project we were asked to conduct three experiments. The three experiments I chose to conduct were Experiment 1‚ Experiment 2‚ and Experiment 4. I have documented my findings for the experiments that were done. In Experiment 1‚ I was to rub my index finger gently over a piece of very coarse sandpaper for a few times. Then‚ I was to rate its coarseness on a scale from 1 (very soft) to 7 (very coarse)
