Answer:
Option B, Get the results approved by government agencies
Explanation:
The findings of the student can be verified by someone who has already conducted research or studies in the same field earlier. Since a government agency would have carried out a sincere study and their findings would be more accurate as compared to any of the secondary sources, newspaper or magazine publication, it would be advisable to get the results verified by some government agency.
Also a finding attested by a government organization is more trusted than its verification from any other sources.  
Hence option B is the correct choice of answer
 
        
             
        
        
        
Answer: Mutualism
Explanation:
Mutualism is a symbiotic relationship in which both interacting species receives the benefit for togetherness.
In the given situation, the birds are receiving food in the form of ticks and the rhinoceros are receiving protection against the predatory blood sucking ticks.
 
        
             
        
        
        
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
 
        
             
        
        
        
<span>The answer is B. 72.25 percent.
The Hardy-Weinberg principle can be used:</span>
<em>p² + 2pq + q² = 1 </em>and <em>p + q = 1</em>
where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq</em> are the frequencies of the genotypes.
<span>The <em>p</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15
To calculate the <em>P</em> allele frequency (<em>p</em>), the formula <em>p + q = 1</em> can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85
Knowing the frequency of the <em>P</em> allele (<em>p</em>), it is easy to determine the frequency of the <em>PP </em>genotype (<em>p²</em>):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.</span>
