If stranded on a deserted island with no freshwater, it is not advisable to drink sea water. Why not?
A)
The salty snacks cause an ionic imbalance that triggers a nervous response.
B)
The salt in the body creates a hypertonic solution around cells, which causes water to diffuse out of cells and make them crenate.
C)
The salt in the body creates a hypotonic solution around cells, which causes water to diffuse into cells and make them cytolyse.
D)
The salt in the body creates an isotonic solution around cells, which causes water to diffuse into and out of cells which makes them unstable.

If stranded on a deserted Island with no freshwater, it is not advisable to drink sea water because B)
The salt in the body creates a hypertonic solution around cells, which causes water to diffuse out of cells and make them crenate. 

Answer:

The correct answer would be B)  The salt in the body creates a hypertonic solution around cells, which causes water to diffuse out of cells and make them crenate.

Seawater contains a very high amount of salt as compared to what our body can process.

The excess salt creates the hypertonic solution that is, it has a high concentration of salt (solute) as compared to the inside of the cell.

Consequently, water moves out of the cell by osmosis which will result in the shrinkage of the cells.

Removal of water from the cells will worsen the situation by increasing the dehydration in the body.  

It is why that seawater is not advisable to drink.
