A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disaccharide) and glucose (a monosaccharide) cannot pass. The membrane separates a 0.2-molar sucrose solution from a 0.2-molar glucose solution. With time, how will the solutions change?a. Nothing happens because the two solutions are isotonic to one another.
b. Water enters the sucrose solution because the sucrose molecule is a disaccharide and thus larger than the monosaccharide glucose.
c. Water leaves the sucrose solution because the sucrose molecule is a disaccharide and thus larger than the monosaccharide glucose.
d. The sucrose solution is hypertonic and will gain water because the total mass of sucrose is greater than that of glucose.
e. After the sucrose dissociates to two monosaccharides, water will be osmostically drawn to that side of the membrane.
