Carson Waters · Answer 1

Volume in side A will be increased so the height in the solution column will rise.

Explanation:

If the membrane is permeable only to sodium chloride, there will be no glucose flow.

As we assume that the membrane allows the passage of water in both directions, there will be a net current from the solution of lower concentration (B) to the side of higher concentration (A)
