Nayla is planning an investigation on the role of osmosis in maintaining homeostasis. She plans to study red blood cells in a liquid suspension,
similar to blood plasma.
For Nayla to observe the greatest variety of osmotic activity in the red blood cells, she should test the effect of which of these independent
variables?
A. temperature of the liquid suspension
B. oxygen concentration of the red blood cells
c. the number of red blood cells per liter of the liquid suspension
D. salt concentration of the liquid that surrounds the red blood cells
