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.
-Refer to the figure. If you examine side A after three days, you should find ________.
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 the 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
