When human red blood cells are placed in a solution of 0.10M NaCl and 0.15M glucose, it:

The behavior of red blood cells in a solution depends on the tonicity of the solution compared to the cells. Tonicity is a measure of the effective osmotic pressure gradient; it is dependent on the concentration of non-penetrating solutes such as NaCl and glucose.

1. First, we need to determine the tonicity of the solution. The solution contains 0.10M NaCl and 0.15M glucose.

2. Glucose is a penetrating solute, meaning it can cross the cell membrane. Therefore, it does not contribute to the tonicity of the solution.

3. NaCl, however, is a non-penetrating solute. It cannot cross the cell membrane and therefore contributes to the tonicity of the solution.

4. The concentration of NaCl in human blood is approximately 0.9%. This is equivalent to a 0.15M solution.

5. Therefore, the solution of 0.10M NaCl is hypotonic compared to the red blood cells.

6. When red blood cells are placed in a hypotonic solution, water will move into the cells by osmosis.

7. This will cause the cells to swell and potentially burst, a process known as hemolysis.

So, when human red blood cells are placed in a solution of 0.10M NaCl and 0.15M glucose, they will undergo hemolysis.
