Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.

To gather data or information or to observe. HOPE THIS HELPS!! IF SOO LET ME KNOOW
Nitroglycerin relaxes the arteries and veins. It pools the blood
in the extremities dropping blood pressure. Chest pain relief can be expected
in 1-3 minutes. Because it is administered sublingually, it is absorbed
directly in the bloodstream. If the chest pain did not improve in 5 minutes, it
should be repeated. It can be repeated the third time( after 5 minutes from
second dose). If the pain doesn't subside after 3 doses, emergency care is
needed.
