Answer #1

3) Since ocean water is more salty than body fluids thus osmosis takes place and fluid start coming out of the blood cell due to which blood cell collapse. Thus, ocean water was not advised to drink.

4) Fresh water contain less ion Concentration than blood fluid. Thus, fresh water is hypotonic compared to lung tissue. When water enters the cells, it causes them to swell. Some of the lung cells may burst. Because capillaries in your lungs are exposed to the fresh water, water enters the bloodstream, diluting your blood. This causes blood cells to burst.
