The best answer is A

Saltwater fish are hypotonic to their surroundings. This means their blood has a higher water concentration than the surrounding sea water.

Due to the fact that there is more salt and less water outside their bodies, there is a tendency to take in salt and lose water.

To counter this, salt water fish drink a lot of the sea water and urinate very little. Special cells in the gills actively eliminate salt at the cost of extra energy and these fishes do not absorb any salt from the water they drink.

ANTONII [103]

Answer:

The correct answer is option D, that is, the elephant will not react.

Explanation:

A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.  

In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.
