Answer:
This hormonal control of blood glucose levels is an examples of negative feedback response.
Explanation:
The blood glucose concentration maintain their concentration through negative feedback mechanisms.Alpha and beta cell present in pancreas. Alpha and beta cell produced insulin and glucagon which act as a antagonistic hormones and control blood glucose level.
Insulin is secreted by beta cell.Beta cell secreted insulin when glucose level increased in the blood.Insulin helps to stimulate liver to absorb glucose.Liver convert glucose to glycogen and adipose cells convert the glucose to the fat.In response, glucose concentration decreases in the blood, and insulin secretion discontinues (through negative feedback from declining levels of glucose)
Glucagon is secreted by alpha cells. when the concentration of blood glucose level drops then alpha cells secrete glucagon into the blood.Glucagon stimulates the liver for release of glucose. When blood glucose levels return to normal then glucagon secretion stopped.Its a negative feedback response.
Im not sure how to awnser this, whats the question?
Answer:
Rotation is when an item or object (specifically the earth) rotates on it's axis.
Revolution is when an item (the earth) orbits or "revolves" around another one (the sun).
The rotation of the earth determines how long a day lasts while the revolution (or orbit) determines how long a year lasts (with all of the season).
