Explanation / Answer

Answer:

Solution A: Crenation

3.21% (m/v) NaCl is a hypertonic solution. So, RBC placed in it will loose water and shrink.

Solution B: Hemolysis

1.65% (m/v) glucose is a hypotonic solution. So, RBC placed in it will absorb water, swell up and burst.

Solution C: Hemolysis

distilled H2O is a hypotonic solution. So, RBC placed in it will absorb water, swell up and burst.

Solution D: Crenation

6.97% (m/v) glucose is a hypertonic solution. So, RBC placed in it will loose water and shrink.

Solution E: Crenation

5.0% (m/v) glucose and 0.9%(m/v) NaCl forms a hypertonic solution. So, RBC placed in it will loose water and shrink.
