Question

1. a blood cell placed in a 10% sodium chloride solution crenates and shrinks because the cell is placed in a(n) ______ solution and water is leaving the cell.

a. hypertonic
b. hypotonic
c. isotonic

Explanation:

A hypertonic solution has a higher solute concentration than the inside of the cell. Water moves out of the cell via osmosis to balance the solute concentration, causing the cell to shrink or crenate. A 10% sodium chloride solution is hypertonic relative to blood cells.

Answer:

A. hypertonic
