The answer to this question would be: vertebrae 
In vertebrae fracture, traction is important to assure immobilization of the vertebrae. Movement can cause the fragment of bone in the fracture damaging the neural tissue in the vertebrae.
To ensure no movement in the neck, metal tongs can be put on the skull. The tongs will help fixate the skull with the shoulder.
        
             
        
        
        
Answer :B. By changing the shape of the enzyme's active site.
check the attachment 
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.
On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape). 
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually
 <u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
 
        
             
        
        
        
The child is more susceptible to diseases than the father because the father has already gained a slight immunity towards the lead by loving in the house longer than the child (assuming the father has lived in the house longer)
        
             
        
        
        
Answer:
the answer is A
Explanation:
Taste stimuli produce depolarizing and hyperpolarizing potentials in individual taste cells.
