Answer:
Uracil
Explanation:
DNA only uses Thymine so that leaves Uracil for RNA because all of the other bases are used for both.
 
        
                    
             
        
        
        
Both population health and public health can include very narrow or very large groups of individuals – some public health initiatives encompass entire countries or regions of the world – and both increasingly rely on digital data assets to identify patterns and aid workers as they address critical wellness needs.
 
        
             
        
        
        
Answer:
the frequency of the resistant allele after one generation is 0.989
Explanation:
Given that :
A farmer plants Bt cotton that is genetically modified to produce its own insecticide. 
Of the cotton bollworms feeding on these Bt plants, only 5% survive 
i.e the survival rate s  = 5% =0.05
unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide
Frequency of R allele = 0.01
In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.
According to Hardy-Weinberg Equilibrium ;
p+q = 1
Let p = R and q = r
R + r = 1
0.01 + r = 1
r = 1 - 0.01
r = 0.99
Now; the  frequency of the resistance allele after one generation can be calculated as :

where ;
q' = R
q = r



q' = 0.989
Thus; the frequency of the resistant allele after one generation is 0.989
