Answer 1

Answer:

Explanation:

1. at in intracellular level, there are different cells or tissues to perform different functions within a cell, like tissues in heart help only the heart to relax and contract.

2. Plasmolysis

3.If a red blood cell is placed in a hypotonic solution, water would naturally enter the cell through osmosis as the concentration of water in the RBC is lower.the RBC will swell up.

4.The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis.

5.On adding salt, the external medium is made hypertonic, i.e., concentration of water is lowered as compared to the concentration of water inside the cell. Thus, water is released from the vegetables due to exosmosis (water molecules goes out of the cell resulting in shrinkage of cell).
