c. Explain why the osmolarity of some of the liquid solutions changed after the red blood cell was added. Describe the processes of the changes to the concentration. Your description should include a minimum of 3 processes. Be specific to receive the full credit. (6pts)

Answers

Answer: lots of words >_>

Explanation:

The osmolarity of a liquid solution can change after a red blood cell is added due to processes involving changes in concentration. Here is a step-by-step explanation of these processes:

1. When a red blood cell is added to a liquid solution, it will attempt to reach equilibrium with its surroundings. Red blood cells are surrounded by a semipermeable membrane that allows certain substances to pass through while restricting others.

2. If the concentration of solutes (such as ions or molecules) in the liquid solution is higher than that inside the red blood cell, water will move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (the solution) through osmosis.

3. This movement of water from inside the red blood cell to the solution will cause the cell to shrink, leading to a decrease in the osmolarity of the solution. The solute concentration in the solution increases as water leaves the cell.

4. On the other hand, if the concentration of solutes in the liquid solution is lower than that inside the red blood cell, water will move from the solution into the cell, causing it to swell. This leads to an increase in the osmolarity of the solution since the solute concentration decreases as water enters the cell.

5. The extent of the change in osmolarity depends on the initial concentrations of solutes in the solution and inside the red blood cell. If the concentrations are similar, there may be little to no change in osmolarity.

In summary, when a red blood cell is added to a liquid solution, the osmolarity of the solution can change due to the movement of water through osmosis. Water moves from areas of lower solute concentration to higher solute concentration, resulting in either the shrinking or swelling of the red blood cell and a corresponding change in the concentration of solutes in the solution.
