happen?
a. Glucose will diffuse from side B to side A.
b. Glucose will diffuse from side A to side B.
c. The water level on side A will increase and on side B will decrease.
d. The water level on side B will increase and on side A will decrease. -
(correct answer) d. The water level on side B will increase and on side
A will decrease.
