Study the illustration. The small blue spheres represent water molecules.

Question

In which direction will water molecules move across the membrane?

Responses

There will be no net movement of water.

There will be no net movement of water.

Water will move from B to A.

Water will move from B to A.

Water will move from A to B.

Water will move from A to B.
Sections A and B are divided by a membrane, with section A containing fewer water molecules than section B

Answer 1

In this scenario, since section A contains fewer water molecules than section B, water molecules will move from the area of higher concentration (section B) to the area of lower concentration (section A). This is to achieve equilibrium.

Therefore, the correct response is: Water will move from B to A.
