In the set-up shown in the figure below, which of the following statements would describe what would be observed after 12 hours of time have elapsed?
A) The level of the solution in the tube would rise because there are now more dissolved solutes present in the beaker than in the tube.
B) The level of the solution in the tube would lower because the glucose and salt would move into the tube.
C) The level of the solution in the tube would rise because there are now more dissolved solutes in the tube than the beaker.
D) The level of the solution would not change as the membrane prohibits any exchange between tube and the beaker.
E) The level of solution in the tubes would see no change because the solute levels are equal on both sides.

The glucose and salts will move across the membrane until they are equal on both sides. The protein is unable to dialyze across the bag. Therefore, the tube will have more dissolved solutes (less water) than the beaker (more water). Consequently, water will move from high to low concentration into the tube and the solution level will rise over time.
