Answer:

The options

A. A

B. B

C. C

D. E

The CORRECT ANSWER IS D.

E.

Explanation:

It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.

If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.

The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
