Question

flasks x, y, and z contain solutions with different concentrations of the solute nacl. flask x has 0.5% nacl. flask y has 0.9% nacl. flask z has 1.5% nacl. red blood cells (0.9% nacl) will be placed into each flask. what will happen to red blood cells in flask z? unchanged, shrink, swell and followed by hemolysis, only swell

Explanation:

Step1: Identify tonicity

Red blood cells have 0.9% NaCl. Flask Z has 1.5% NaCl.

Step2: Analyze osmosis

Flask Z is hypertonic to red - blood cells. Water will move out of cells.

Step3: Determine cell change

As water moves out, cells will shrink.

Answer:

shrink
