    Refer to the figure, below, to answer the following two questions. 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 molar glucose and 0.5 molar sodium chloride (NaCl) and side B is filled with a solution containing 0.8 molar glucose and 0.4 molar sodium chloride. Initially, the volume in both arms is the same.  If you examine side A after 3 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 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.
