the effect of different concentrations of ethanol on the permeability of beetroot cell membranes. Prediction: By exposing a membrane to a solvent‚ ethanol‚ it will increase its permeability. So the higher the concentration of the solvent‚ the more permeable the membrane will be. But if the concentration of the ethanol is beyond a certain limit‚ it may break down the cell membrane to the point where there is in fact no overall effect as the ethanol would disturb the lipids in the membrane.
