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,
 
        
             
        
        
        
Answer:
37.5%
Explanation:
These here are
Black (AA or Aa) and albino (aa)
Agouti (Bb or BB)
Thus, a cross between 
AaBb and aaBb
The percent of the progeny which are likely to be agouti would be
 A. a. B. b
a. Aa. aa. B. BB. Bb
 a. Aa. aa. b. Bb. bb
The probability of agouti would be
1/2 (Aa) * 3/4 (BB or Bb)
= 3/8
= 37.5%
 
        
                    
             
        
        
        
Whatd did she discover?? it doesnt make sense
        
             
        
        
        
100 percent, because if both parents have the same genotype of Tt then most likely the child will have 100percent.
