Characteristics of Living Organisms: Ability to reproduce independently, ability to grow
Characteristics of Viruses: Not made of cells, have a protein coat instead of a membrane. 
Characteristics of Both: Can have a DNA genome, may mutate and evolve

Answer:
a) 0.56moles
b) 2.78moles
Explanation:
The number of moles can be calculated by using the formula;
Mole (n) = Mass (M) ÷ Molar mass (MM)
For a glucose molecule, with chemical formula: C6H12O6
Where atomic mass of C= 12, H=1, O= 16
Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)
= 72 + 12 + 96 
= 180g/mol
a) In 100g of glucose; 
Mole = 100/180
Mole = 0.56moles
b) In 500g of glucose
Mole = 500/180
Mole = 2.78moles
 
        
             
        
        
        
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,
