Answer:
B. Failure to maintain homeostasis may result in a pathological condition.
D. Blood glucose regulation is not an example of homeostatic regulation.
Explanation:
Homeostasis refers to the balance and equilibrium conditions of the body of living organisms. Homeostasis is very important for the optimum growth and functioning of the body. There are certain diseases occur such as diabetes and heart failure etc when homeostasis of the body is disturbed. Blood glucose level is controlled by insulin harmone. If insulin is not secreted by pancreas so homeostasis of the body will be disturbed.
Answer:
D. Blood glucose regulation is not an example of homeostatic regulation
Explanation:
The maintenance of relatively constant internal environment of an organism is called homeostasis.
The blood glucose level fluctuates with different body conditions. It is especially high after glucose diet above threshold , but drops with time and remain stable at threshold
Two pancreatic hormones regulates this in the blood, Insulin which reduced blood glucose levels by converting excess blood glucose to glycogen, and facilitate entry into the cells for cellular utilization through Glut transporters
While if the blood glucose level drops below the critical points, the pancreas is stimulated for Glucagon hormone secretion, which in turn stimulated the liver to converts stored glycogen in the muscles back to glucose for body use.
This is an example of negative feed back mechanism, because high blood sugar causes the release of insulin which reduced its level, by increase it storage as glycogen or cellular uptake, and low levels causes release of glucagon to elevate back to the threshold levels.
