A “cell” with a selectively permeable membrane contains 0.02 M sucrose, 0.01 M glucose, 0.04 fructose, and 0 M lactose. It is immersed in a  solution consisting of 0.05 M sucrose,  0.03 M glucose, 0.01 M fructose, and 0.03 M lactose. The membrane is permeable to water and to the simple sugars glucose and fructose, but is impermeable to the disaccharides sucrose and lactose.   After waiting for almost a hour after being placed into the beaker, which of the following changes would occur?
