the diagram below shows a cell placed in a solution.
only water is allowed to move in and out of the cell. what will most likely happen to the cell?
a it will expand as water moves out of it
b it will shrink as water moves out of it
c it will expand as water moves into it
d it will shrink as water moves into it

Explanation:

The cell has a 20% salt - solution and the surrounding is a 40% salt - solution. This creates a hypertonic environment outside the cell. In a hypertonic environment, water moves out of the cell by osmosis (from an area of lower solute concentration inside the cell to an area of higher solute concentration outside the cell). When water moves out of the cell, the cell will shrink.

Answer:

B. It will shrink as water moves out of it.
