Question

3. What will happen when resins and RBCs placed in hypotonic medium? How they differ in their response? Why are we advised to rinse our mouth with luke warm salty water during swollen gum condition?

Answer 1

Answer:

Raisins will swell due to movement of water inside them in hypotonic solution.

A red blood cell will swell and undergo hemolysis (burst) when placed in a hypotonic medium.

Since the RBC does not have any cell wall to maintain cell rigidity and shape, it will expand due to the entry of water until it eventually burst. the cellwall of the raisins allow them to swell, because it prevents the cell from bursting.

This warm drink also gives relief from bleeding and swollen gums, which are the first signs of gum disease caused by bacteria. Rinsing your mouth with salt water can help reduce inflammation and fight the bacteria.
