Q. What would happen if red blood cells were placed in distilled water?
Answer: They would increase in volume and burst
Notes: When red blood cells are placed in distilled water, the water molecules move into the cells by osmosis because the cells have a higher solute concentration than the distilled water. This influx of water causes the red blood cells to swell and eventually burst in a process known as hemolysis. This demonstrates how osmosis, a vital biological process, can result in cell damage when the external conditions are not balanced.
