Chambers A and B are separated by a membrane permeable to substance X. The concentration of X is 5% in A and 15% in B. The volume of A is three times that of B. Which of the following will occur?

A. Although diffusion is random, the result will be the net movement of X from B to A.

B. Because diffusion is random, diffusion will take place without changing the concentration of X in either A or B.

C. There will be no net movement of X because there is no energy available to transport X from B to A.

D. There will be no net movement of X because the total amount of X is the same in A and B.

Although diffusion is random, the result will be the net movement of X from B to A.

Explanation:

Diffusion is the process of movement of substances from the region of their higher to that of the lower concentration. It is a random and passive movement. There is no requirement of energy input for diffusion. The diffusion of substances is driven by the concentration gradient only.

According to the given information, chamber B has a higher concentration of substance X than the chamber A. The membrane that separates these two chambers is permeable to the substance X. This would allow the movement of substance X from B to A. Therefore, diffusion of substance from B to A chamber would increase its concentration in chamber A.
