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.

At the beginning of the U-tube experiment illustrated above, which of the following statements is true?

#Unit 2. Cellular Organization
  1. Side A is hypertonic to side B.

  2. Side A is hypotonic to side B.

  3. Side A is hypertonic to side B with respect to glucose.

  4. Side A is hypotonic to side B with respect to NaCl.
