If a 5% glucose solution were separated from a 10% glucose solution by a membrane that was permeable to both water and glucose
A) glucose would move from the 5% solution to the 10% solution
B) water would move from the 5% solution to the 10% solution
C) the movement of glucose between the two solutions would be equal
D) water would move from the 10% solution to the 5% solution

Since the membrane is permeable to both water and glucose, both substances can move across the membrane. However, water will move from areas of higher concentration to areas of lower concentration in a process called osmosis. In this case, the 5% glucose solution has a lower concentration of solutes (glucose) compared to the 10% glucose solution, so water will move from the 5% solution to the 10% solution to equalize the concentration of solutes on either side of the membrane. This movement of water will not affect the concentration of glucose in either solution, so its movement between the two solutions will be equal. Thus, option B is the best choice as it correctly explains the movement of water in the system.
