Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Tahira placed a collection of red blood cells into a container filled with an unknown solution.Once in the container, Tahira noticed that the red blood cells swelled and some of them burst.
A
An isotonic solution
B
A hypotonic solution
C
A hypertonic solution
D
None of the above
Explanation: 

Detailed explanation-1: -The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis. If a red blood cell is placed in a solution that contains 0.85% NaCl the water moves equally out and into the cell, the solution in the cell and the solution around the cell are the same or in equilibrium.

Detailed explanation-2: -When a red blood cell is placed in a hypotonic solution, there will be a net movement of free water into the cell. This situation will result in an increased intracellular volume with a lower intracellular solute concentration. The solution will end up with a higher overall solute concentration.

Detailed explanation-3: -Due to the diffusion process which states that when a cell is placed in a concentrated solution, water moves from a high concentration of water (RBC) to a low concentration of water (saline water). Due to this a red blood solution loses water and shrinks in a concentrated saline solution.

Detailed explanation-4: -Answer and Explanation: Nothing happens to red blood cells in an isotonic solution as an isotonic solution has the same osmotic pressure as a red blood cell.
