fill in the blank question
a cell that has an equal concentration of solutes inside and outside of its plasma membrane is in a(n) □ solution.

Explanation:

In biology (a subfield of Natural Science), when the solute concentration inside and outside a cell is equal, the solution is called isotonic. This is based on the concept of tonicity, where isotonic solutions have no net movement of water across the cell membrane due to equal solute concentrations.

Answer:

isotonic
