Answer:
The correct answer is- hormone signal amplification
Explanation:
The signals that are received by the cell can be amplified in the cell which results in the production of more than one molecule of the product. There is a signal pathway in every cell and the longer the signal pathway the more amplification chances are there.
For example, one membrane receptor is able to produce 10 secondary messengers and each secondary messenger generates 10 mRNA transcript so here the signal amplified by 1000 folds.
So in this question, it is seen that a small amount of releasing factor causing the release of a much greater amount of cortisol which shows the example of hormone signal amplification.
