Two solutions are separated by a semipermeable membrane with the same properties as a cell membrane. Solution A is a 5 percent salt and solution B is 10 percent salt. Under these conditions, which of the following would most likely occur?
A) Water will move from solution B to solution A.
B) Glucose will move from solution A to solution B.
C) Water will move from solution A to solution B.
D) Glucose will move from solution B to solution A.

When two solutions of different concentrations are separated by a semipermeable membrane, water tends to move from the solution with lower concentration of solutes to the solution with higher concentration of solutes (osmosis). In this case, solution A has a lower concentration of salt than solution B, so water will move from solution A to solution B. Glucose and other molecules are not affected because the membrane is selectively permeable only to water. Therefore, option C is the correct answer.
