Explanation:
Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is 
pH = -log[H+]. 
...where pH is -base 10 log of the concentration of hydrogen ions within the solution.
Initial volume= 20 mL
Final volume= 600 mL
# of dilutions=  = 30
 = 30
for a pH 2= [H+]= 
∴ [H+]=  
and pH is an antilog of [H+]= - log 
∴pH = 3.47

Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:  
The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.
 
        
             
        
        
        
Answer:
b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.
Explanation:
Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.
