Hypothesis - the levels will rise in both but will rise more in the 1 molar solution (about double the length).

Question 1: It is beneficial for a cell to be selectively permeable so that it can regulate the types of molecules it lets into its membrane. It could be very harmful for the cell if it is exposed to the molecules that are not nutrients for the cell.

Question 2: Yes, we predicted that it would be around 2x the length in the 1 molar solution because we figured that .5 molar solution would diffuse about half the amount of the other.

Question 3: The rate of diffusion would increase since the water molecules will be moving faster and will be able to permeate the membrane at a faster rate.
