All the hormones are proteins,peptides,and amino acid derivatives except:

According to the accepted concept of hormone action,if receptor molecules are removed from target organs,what will be the effect?

What is the role of a second messenger in the mechanism of protein hormone action?

In multicellular animals, intercellular communication is mediated by which of the following?

Describe the mechanism of steroid and peptide hormone action with a diagram.

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: $FSH$,which interacts with membrane-bound receptors,does not enter the target cell.
Reason $(R)$: Binding of $FSH$ to its receptors generates a second messenger (cyclic $AMP$) for its biochemical and physiological responses.
In the light of the above statements,choose the most appropriate answer from the options given below:
