Question

which of the following solutions when added to red blood cells will cause the cell membrane to remain intact and the solution to appear cloudy and opaque. select all answers that apply.□ isotonic solution□ hypotonic solution□ hypertonic solution

Explanation:

• Isotonic solutions have the same solute concentration as red blood cells, so no net water movement occurs. The cell membrane stays intact, and the solution remains cloudy/opaque because cells are suspended.
• Hypotonic solutions have lower solute concentration than cells: water flows into cells, causing them to burst (hemolyze), which makes the solution clear.
• Hypertonic solutions have higher solute concentration than cells: water flows out, cells shrink (crenate), and the solution becomes clearer as cells clump or shrink.

Answer:

Isotonic solution
