Question

in which kind of solution is the concentration of solutes the same inside and outside of the cell?
isotonic
hypertonic
hypotonic
concentrated

Explanation:

In an isotonic solution, the solute - concentration is equal inside and outside the cell. In a hypertonic solution, the solute concentration outside the cell is higher. In a hypotonic solution, the solute concentration outside the cell is lower. A concentrated solution generally refers to a high - solute concentration relative to some standard, but not specifically equal to the cell's internal concentration.

Answer:

A. isotonic
