The answer is freshwater snail
The correct choice is that it extends until depths of around 60 m where sediments cannot move anymore. The important thing is that it certainly is not just the contact point of water and land; it goes into the sea until this point, where also enough light reaches the bottom for plants to do photosynthesis. D is wrong because breakers do not play a role in this definition, although it can vary from context to context (sea, lakes etc.).

Answer:
The correct answer is b) When a plant cell is placed in concentrated salt water, water moves out of the cell.
Explanation:
Osmosis is the movement of solvent molecules from an area of less concentration of solute to high concentration of solute to equalize the concentration of both the side of the cell.
So water will move outside the cell when any cell will be placed in a concentrated salt water because the concentration of solute is high in salt water and low inside the cell.
Therefore when a plant cell is placed in salt water the osmosis of water takes place from inside to outside the cell. So the right answer is b.
I would believe the correct responses would be option 1,2,4.
