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• your answer is incorrect.

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 suspended cells make the solution cloudy/opaque.
• Hypotonic solutions have lower solute concentration than cells: water flows into cells, causing them to burst. This releases hemoglobin, making the solution clear, not opaque, and destroys cell membranes.
• Hypertonic solutions have higher solute concentration than cells: water flows out of cells, causing them to shrink and potentially rupture, damaging the cell membrane, and the solution will not remain cloudy/opaque as expected.

Answer:

Isotonic solution
