In _____ conditions, the cell wall will help prevent the cell from bursting. A. hypertonic B. hypotonic C. isotonic D. All of the choices are correct.

The correct answer is B. Hypotonic.

Here's why:

A. Hypertonic conditions: In this scenario, the concentration of solutes is higher outside the cell than inside. Water will move out of the cell to try to balance the concentration. The cell will shrink, not burst.

B. Hypotonic conditions: In this case, the concentration of solutes is lower outside the cell than inside. Water will move into the cell to try to balance the concentration. Without a cell wall to provide a rigid structure, the cell could take in too much water and burst. So, in hypotonic conditions, the cell wall will help prevent the cell from bursting.

C. Isotonic conditions: Here, the concentration of solutes is equal inside and outside the cell. Water will move in and out of the cell at an equal rate, so there's no net movement of water. The cell won't shrink or burst.

D. All of the choices are correct: This is not correct because, as explained above, only in hypotonic conditions will the cell wall help prevent the cell from bursting.
