A red blood cell placed in a solution containing more than 0.9% (mass/volume) sodium chloride will:
Aburst as water flows into it
Bswell as water flows into it
Cshrink as water flows out of it
Dremain unchanged in volume
Answer & Solution
Correct answer: C. shrink as water flows out of it
1. The fluid in a blood cell is isotonic with 0.9% NaCl (normal saline).
2. A solution above 0.9% NaCl is hypertonic, so water flows out of the cell by osmosis.
3. Losing water, the cell shrinks (it would swell only in a hypotonic solution).
