Aziz has Down syndrome.
Down syndrome or trisomy 21 is a genetic disorder which results in physical growth delays and mild / moderate intellectual disability. Patients with this disorder have characteristic facial features and their IQ is usually equivalent to the mental ability of an 8 or 9-year-old child.
 
        
             
        
        
        
Answer:
Gonadotropins are polypeptide hormones and are secreted by the anterior pituitary gland.
Explanation:
Hypothalamus releases GnRH i.e gonadotropin releasing hormone which stimulates the anterior pituitary to secrete gonadotrophs such as FSH, ICSH and LH.
FSH (follicle stimulating hormone): In males it stimulates spermatogenesis. In females it stimulates growth of ovarian follicles. 
ICSH (Interstitial cell stimulating hormone): In males, secretion of testosterone.
LH (Luteinising hormone): In femalestogether with FSH, it triggers ovulation, stimulates conversion of broken ovarian follicle into corpus luteum. 
 
        
                    
             
        
        
        
Answer/Explanation:
In humans, we breathe in oxygen via the respiratory system. The oxygen enters the lungs. The air sacs in the lungs - the alveoli - are the site of gas exchange in the lungs and are where the circulatory and respiratory systems interact. 
The alveoli take in the oxygen, where it diffuses into the capillaries (circulatory system). Blood, which passes through the capillaries takes this oxygen to all the cells in the body. Oxygen binds to haemoglobin in red blood cells, which transport it around the body. 
Additionally, blood also transports carbon dioxide back to the alveoli of the lungs, where it diffuses into the lungs and is expelled when we breathe out

<span>The answer would be: as the bicarbonate ion in the plasma after first entering the red blood cells
Carbon dioxide will be changed into bicarbonate ion that released into the plasma. That is why the level of carbon dioxide will influence the pH of the blood. The process will produce hydrogen ion so higher carbon dioxide will result in acidosis. It is important to keep the carbon dioxide level at a certain point to prevent blood pH stable</span>
