Question

a student performed an investigation on the homeostasis of red blood cells and the effect of different environmental conditions on the red blood cells. images of the results of the investigation were captured under the microscope and are illustrated here. which statements are supported by the results of the investigation? select all that apply. a the red blood cells on slide ii are in a state of homeostasis. b the red blood cells depicted in slide i were likely in a hypertonic environment. c all three slides indicate red blood cells in states of homeostasis. d the red blood cells depicted in slide iii were likely in a hypertonic environment. e the red blood cells depicted in slide iii gained water at a rate that is greater than the rate of loss of water.

Explanation:

• Homeostasis in red - blood cells refers to a stable internal state. In a hypertonic environment, water leaves the cells causing them to shrink. In a hypotonic environment, water enters the cells causing them to swell.
• Slide II shows normal - shaped red - blood cells, indicating homeostasis. Slide I shows shrunken cells, likely in a hypertonic environment. Slide III shows swollen cells, likely in a hypotonic environment where water gain exceeds water loss.

Answer:

A. The red blood cells on slide II are in a state of homeostasis.
B. The red blood cells depicted in slide I were likely in a hypertonic environment.
E. The red blood cells depicted in slide III gained water at a rate that is greater than the rate of loss of water.
