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.
 
        
             
        
        
        
The answer could be A. 
A bacterial cell is about 0.2-20 um, while a typical eukaryotic cell is about 10-100um, according to many sources of research.
 
        
             
        
        
        
The reason why the RNA has decrease stability compared to
DNA is because the DNA, is lacking a hydroxyl group in which making it more
stable than of the RNA, that is why RNA has decrease stability than the DNA.
