The signal transduction pathways that lead to physiological or developmental responses, these responses fall into two general categories;
a) Ion fluxes, which cause relatively rapid turgor responses
b) the possible chain of events constituting the signal transduction pathways that bring about these effects
c) Altered gene expression, which typically results in longer-term responses
d) Gene expression altered shows short-term response

Transplantation of different regions of the presomitic mesoderm (PSM) to the limb field causes changes in limb size. Following statements are:

A. Transplanting PSM from the level of the presumptive forelimb to the flank (region between the forelimb and hindlimb) results in a larger forelimb bud.

B. Transplantation of PSM from the flank region to the level of the presumptive forelimb results in a smaller forelimb bud.

C. Transplanting PSM from the level of the presumptive forelimb to the flank (region between the forelimb and hindlimb) results in a smaller forelimb bud.

D. Transplantation of PSM from the flank region to the level of the presumptive forelimb results in a larger forelimb bud.

Epinephrine binds to the same type of receptors in liver, fat, and smooth muscle cells. Yet in liver, glycogen breaks down; in fat, triacylglycerols break down; and smooth muscle cells relax. How can the same hormone produce three such different responses?
