The answer is A. 0.54. 
In a population p+q=1 (we have 2 alleles only). 
The question states that 0.21 of the population(21%) have short legs meaning they are q^2. 
So q=rad0.21=0.4582. 
And p=1-q=0.5417.

ANSWER:</h2>
 Glycogen and triglycerides
<h2>
EXPLANATION:</h2>
Living organisms employ two main kinds of energy storage. Energy-rich molecules such as glycogen and triglycerides stock energy in the formation of covalent chemical bonds. Cells integrate such molecules and store them for the later discharge of the energy.
