If the concentration of sugar molecules in water on side "A" of a selectively permeable membrane is 5 percent, and the concentration of sugar molecules in water on side "B" of a selectively permeable membrane is 15 percent, which way will the water move and why?
a. The water will mostly move from side "B" to side "A" because the water concentration is higher on side "B."
b. The water will mostly move from side "A" to side "B" because the water concentration is higher on side "A."
c. The water will mostly move from side "A" to side "B" because the water concentration is higher on side "B."
d. The water will not move at all because the water concentrations are isotonic.
Ans: b. The water will mostly move from side "A" to side "B" because the water concentration is higher on side "A."
