Question

water will move out of a cell placed in a(n) ___ solution.
hypertonic
isotonic
aqueous
hypotonic

Explanation:

In a hypertonic solution, the solute concentration outside the cell is higher than inside. Osmosis causes water to move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell). In isotonic solutions, there is no net water movement. Aqueous just refers to a water - based solution and is not relevant here. In hypotonic solutions, water moves into the cell.

Answer:

A. hypertonic
