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.
A. They live in the polar regions of the Northern and Southern Hemispheres.
B.DNA before moving into mitosis.
The above figure represents Ionic bond formed between Sodium (Na) and Chlorine (Cl) where, Sodium transfers its one electron to Chlorine in order to complete their Octets.
Correct choice - A. Ionic bond
Isotonic, Hypotonic, and Hypertonic Solutions. Water moves readily across cell membranes through special protein-lined channels, and if the total concentration of all dissolved solutes is not equal on both sides, there will be net movement of water molecules into or out of the cell.
