The arrival or the introduction of the crabs in the environment altered the previous habitat of the mussels and led to the adaptation of the better trait quality in the mussel species.

The trait of the thick shells underwent natural selection as they were favoured for the changed conditions. The mussel having thick shells have high chances of survival over thin-shelled mussels as the crab will find it hard to attack the thick-shelled mussels.

Therefore, option A. change in environment, option B. natural selection and option E. chances of survival are the correct statements.

Plasmolysis

Explanation:

In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.

The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.

The image 2 plant cell is exposed to a solution which is high concentrated solution.

Due to this high concentrated  solution the water present in  the cell is send out by exosmosis.

Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from  cell wall.

This shrinkage of protoplasm by loss of water is called plasmolysis.
