C. A and B correct answers Questions 3-6 refer to the figure below
Five dialysis bags, constructed from a semi-permeable membrane that is impermeable to
sucrose, were filled with various concentrations of sucrose and then placed in separate
beakers containing an initial concentration of 0.6 M sucrose solution. At 10-minute intervals,
the bags were weighed and the percent change in mass of each bag was graphed.
