hey!!
_______
there is a concept called 'Osmosis' which can answer your question.
osmosis is defined as flow of solvent towords the highly concentrated solution through semi permiable membrane.
semi permiable membrane is a type of membrane which selectively allows flow of solvent through it like Red Blood Cell RBC has a membrane which is semi-permiable.
For a time being consider you have put a red blood cell in a beaker containing pure water (in general we consider pure water is just H2O with pH of 7 i.e. neutral and no minerals at all! )
As the cell consist of cell organells and solutes, proteins (in our case Haemoglobin too) it is considered as concentrated solution and hence according to the phenomenon of osmosis the pure water will enter in the cell through cell membrane (a semi permiable membrane) and starts filling the cell and RBC starts to swell. After a time being when the cell swells up to its limit.
osmosis would stop at the time when concentration inside and out of the cell equalizes but in this case its quite not possible as the water is soluteless.
and hence as cell still has the solutes present in it because of which the flow of pure water continues inside the cell and cell bursts releasing all the material in the water.
hope help u!!

Answer:
- If you add blood in pure water, the molecules of water enter the blood cells through osmosis. The red blood cells will swell up and eventually burst.
B-If you add blood in saline solution which is a hyertonic solution, it results in the shrinkage of red blood cells because the water diffuses out of the cells.
C- 0.9% nacl is isotonic to blood so nothing will happen whereas the 5M of glucose of solution in the same solution will trigger plasmolysis due to dehydration of cells.
