Final answer:
In a hypertonic solution, an animal cell will shrink or crenate as water leaves the cell.
Step-by-step explanation:
In a hypertonic solution, such as seawater, the fluid contains less water than the cell does, causing the water to leave the cell. This leads to the cell shrinking or crenating. Animal cells, like red blood cells, may shrivel and compromise their functions in a hypertonic solution.
