Sharp teeth that are constantly replaced would be the answer! In order for it to be a specific adaptation you would need the detail of why the animal has that adaption for example fins for stability:)
        
                    
             
        
        
        
The correct answer is D) 0,81
When there is Hardy-Weinberg equilibrium like in  this  case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes. And we have:
p²+2*p*q+q²= 1       <em>p+q= 1     p=1-q</em>
q= 0.1     p= 1-0.1= 0.9
p²=0.9²= 0.81
 
        
             
        
        
        
Hi!
The answer is B) it should be repeated by other scientists.
Hope this helps!

Answer:
Considering the boys' situation, the boys live in the rural areas of one of the western United States, e.g. California.
Explanation:
Hantavirus is spread by rodents and is most common in rural areas of the western United States during the spring and summer months.  Hantavirus pulmonary syndrome also occurs in South America (especially in Argentina, Chile, Uruguay, Paraguay, Brazil, and Bolivia).  Hantavirus cases have also occurred in Canada and some parts of Asia, where they reportedly caused kidney disorders rather than lung problems.
 
        
             
        
        
        
You can tell if matter is conserved if the substance changes . If the substance changes then matter has been conserved .
