Question

these micrographs show the effects of various aqueous environments on red blood cells. identify the correct environment depicted in each pane 2014 brooks/cole, cengage learning hypotonic isotonic hypertonic

Explanation:

• Hypotonic: In a hypotonic environment, water enters red blood cells, causing them to swell and potentially burst (hemolysis). Panel B likely shows swollen cells, so Hypotonic corresponds to B.
• Isotonic: An isotonic environment has the same solute concentration as red blood cells, so cells maintain their normal shape (biconcave discs). Panel C shows normal - shaped red blood cells, so Isotonic corresponds to C.
• Hypertonic: In a hypertonic environment, water leaves red blood cells, causing them to shrivel (crenation). Panel A shows shriveled cells, so Hypertonic corresponds to A.

Answer:

Hypotonic - B
Isotonic - C
Hypertonic - A
