levacccp [35]

Answer:

Phosphates are critical part of life because of the diverse roles they perform in the lives of living organisms, especially in DNA and RNA molecules.

It is also plays vital roles in carbohydrate metabolism, fat metabolism, protein synthesis and repair of worn out tissues. Oxygen on the other hand is required for oxidation of biological fuel and for breathing.

Fofino [41]

Answer: .374 and .626

Explanation:

5. total number of alleles = 4712 + 2816 = 7528

       frequencey of B allele = B allele / total number of alleles --> 2816/7528 = 0.374                

             

6. total number of alleles =  4712 + 2816 = 7528

   freq of b allele = b allele/total number of alleles --> 4712/7528 = 0.626

We can confirm our answer as correct because if we add up the answers to 5 and 6 we should get one:

0.374 + 0.626 = 1
