Question

red blood cells develop abnormal notchings on their cell membranes are considered ____.○ crenated because they were exposed to a hypertonic solution○ crenated because they were exposed to a hypotonic solution○ lysed because they were exposed to a hypertonic solution○ lysed because they were exposed to a hyptonic solution

Explanation:

When red blood cells are in a hypertonic solution, water moves out of the cells via osmosis, causing the cell membrane to shrink and form abnormal notchings (a state called crenation). In a hypotonic solution, water moves into cells, leading to lysis (bursting) instead of notching.

Answer:

A. crenated because they were exposed to a hypertonic solution
