If a 20% glucose solution were separated from a 10% glucose solution by a permeable membrane:
A) glucose would move from the 20% solution to the 10% solution.
B) water would move from the 10% solution to the 20% solution.
C) water would move from the 20% solution to the 10% solution.
D) both A and B would occur.

In osmosis, water moves from a lower solute concentration to a higher solute concentration. Thus, water would move from the 10% glucose solution (lower solute concentration) to the 20% glucose solution (higher solute concentration). Additionally, glucose would move from the 20% solution to the 10% solution to reach equilibrium if the membrane allows glucose molecules to pass through.
