What happens to blood cells when placed in a hypertonic solution?

Options

  1. AThey swell
  2. BWater flows into the cells
  3. CThey shrink
  4. DWater flows out of the cells

Correct answer

C. They shrink

Step-by-step solution

The paragraph explains that when blood cells are placed in a hypertonic solution (containing more than 0.9% sodium chloride), water flows out of the cells, causing them to shrink.
