Question

9. I RBC is placed in 0.91% NaCl solution then it will (a) shrink (6) swell (c) neither shrink nor swell ​

Answer 1

Answer:

C) neither shrink nor swell

0.91% solution of NaCl is isotonic to human blood (R.B.C.). Therefore, nothing will happen. A hypertonic solution is the one that contains the solute concentration higher than that inside the cell. When they are placed in a 0.91% of NaCl solution,as the concentration is high outside the cell,so water would inside the cell and cell would swell.
