Answer:
C. Suspension system
Explanation:
When dealing with prosthetic limbs the suspension system is how the prosthetic remains attached to the residual limb. This system makes sure that the prosthetic is firmly attached and only has the necessary movement for the prosthetic but nothing more. There are a couple of different suspension systems, the three most widely used ones would be Anatomic suspension, belt suspensions, and upper limb suspension systems.
 
        
             
        
        
        
EDTA inhibits the activity of DNase during DNA isolation process.
DNase is an enzyme which degrades DNA using divalent metal ions like Mg^{2+} . These metal ions act as cofactor for the proper functioning of DNase. 
EDTA chelates the divalent metal ions and thus does not allow DNase to access them. 
Therefore in this way DNA is prevented from degradation during its isolation.
 
        
             
        
        
        
Answer:Carbon is the basic building block to most cells in the body. It helps with cellular respiration by which your body releases energy stored in glucose and the glucose compound is composed of carbon, hydrogen, and oxygen.
