The solutions in the arms of a u-tube are separated at the bottom of the tube by a selectively permeable membrane. the membrane is permeable to sodium chloride but not to glucose. side a is filled with a solution of 0.4 m glucose and 0.5 m sodium chloride (nacl), and side b is filled with a solution containing 0.8 m glucose and 0.4 m sodium chloride. initially, the volume in both arms is the same.

a. a decrease in the concentration of nacl and glucose and an increase in the water level.

b. a decrease in the concentration of nacl, an increase in water level, and no change in the concentration of glucose.

c. no net change in the system.

d. a decrease in the concentration of nacl and a decrease in the water level.

e. no change in the concentration of nacl and glucose and an increase in the water level.
