Answer: Option D.
The transfer of the methyl group from adomet to an acceptor yields s adenosylhomocysteine.
Explanation:
S- adenosine methionine is a co substrate and one of the naturally occurring sulfonium ions in the body. It is synthesized from methionine which is abundant in animal derived protein. It is metabolised in the liver where it is converted to S adenosine methionine by the enzyme methionine adenosyltransferase. It involve the transfer of methyl group. It is use in medicine as alternative aid to reduce depression.
 
        
             
        
        
        
Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!
Explanation: 
Shivering as a natural, involuntary response to generate heat is an example of  maintaining homeostasis by regulating body temperature.
Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.
When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.
The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.
Hopes this helps happy early Christmas!!!! :D
