If I had an experiment where I was testing how the membrane permeability is affected by ethanol, and by doing this had to observe thin onion slides with different ethanol concentrations and had to count how many nuclei were seen through the microscope once being stained. My results showed that at higher concentrations of ethanol, more nuclei were observed. How would I make a conclusion from the data I collected. I don't really understand why increasing the ethanol concentration means more nuclei is seen in the cells.
talk about the ethanol dissolving the phospholipid bi layer of the membrane, and the protein as the tertiary structure is ruptured. Also reliability- didn't do any repeats etc, you can use repeats to make an average so it is more accurate. do your results support the hypothesis-ive also got it tommorow and this is what you need to know
