You place a marine critter in a solution with an unknown concentration. in two hours, you examine the critter and notice that all its cells are shriveling. what is the tonicity of the tissue fluids inside of cells of the critter?

Hypertonic

Explanation:

The cells of the critter are shriveling indicating that there is a high solute concentration in its cells. Hypertonicity causes the cells to shrink because water is leaving the cells to the external solution which one can deduce is also hypertonic.
