Solution A is a 50% glucose solution. Solution B is a 25% glucose solution. The two solutions are separated by a selectively permeable membrane. Based on this information, what substance, and in which direction, would move across the membrane?
A) There would be a net movement of water from solution A to solution B.
B) There would be a net movement of water from solution B to solution A.
C) There would be a net movement of glucose from solution A to solution B.
D) There would be a net movement of glucose from solution B to solution A.

Question

Water moves from areas of lower solute concentration to areas of higher solute concentration across a selectively permeable membrane, so water would move from solution B (25% glucose) to solution A (50% glucose) to try to equalize the concentration on both sides of the membrane.
