Roal the following information and refer to Figure 7.4 to answer questions 13 and 24 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 massed (weighed) and the percent change in mass of each bag was graphed Five 60 Time (minutes) Figure 74 13) Which line represents the bag with the highest initial concentration of sucrose? 13) 4) Which line represents the bag that contained a solution isotonic to the 0.6 molar solution 14) at the beginning of the experiment? 15) Which of the following metabolic processes can occur without a net influx of other process? B) amino acids protein c) GH1206 +602 6CO2 +6H2O D) ADP + Pi ATP + H2O E) glucose + fructose sucrose 16) Which of the following would likely move through the lipid bilayer of a plasma membrane most 16) rapidly?
