The information from a signal molecule present outside the cell elicits intercellular response when the G protein coupled receptors interact with the wide variety of molecules on the outer surface of the cells.
G Proteins are the specialized proteins having the ability to bind GTP and GDP and is of three units called Alpha, Beta and Gamma subunits which together formed G proteins.
When G protein is activated it will bind GTP and each receptor binds in lock and key method and binding result into conformational change which will trigger a complex chain of events influencing different cell function.
Features exhibited by Signal Transduction System are:
1. Specificity- Signal molecules fits binding site on its complementary receptor. Other signal do not fit
2. Amplification- When enzymes activates enzymes, the number of affected molecules increases.
3. Desensitization- Receptor activation triggers a feedback circuit that shuts off the receptor or removes it from the cell surface.
4. Integration - When two signals have opposite effects on a metabolic characteristics outcome results from the integrated input from both the receptor.

Answer:
Yellow Bone Marrow and Red Bone Marrow I believe.
Answer:
A. Increase
B. Increase
C. Decrease
D. Remain fairly constant or change slightly
E. Increase
F. Increase
Explanation:
A. Following deep breathing of room air, the partial pressure of oxygen in plasma will increase because of higher concentrations of oxygen.
B. Following deep breathing of room air, the partial pressure of carbon dioxide in plasma will decrease because because of higher concentrations of oxygen and increase in oxygen uptake by the lungs.
C. Following deep breathing of room air, respiratory drive will decrease of saturation of blood and tissue with oxygen.
D. Following deep breathing of room air, plasma oxygen content will remain fairly constant or change just slightly because the oxygen saturation levels will have been attained.
E. Following deep breathing in and out of a small paper bag, respiratory drive will increase because of the higher levels or increase in partial pressure of carbon dioxide
F. Following deep breathing in and out of a small paper bag, plasma carbon dioxide content will increase as carbon dioxide are produced from exhalation while oxygen is not being replenished.
