Homework Help: biology

Posted by anonymous on Tuesday, January 31, 2012 at 6:08pm.

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.
