Answer:
0.4550
Explanation:
In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.
In this case, there is Hardy Weinberg Equilibrium, so the following will be true:

Where:
frequency of RR
frequency of Rr
frequency of rr
The question is what is the frequency of heterozygotes, or, what is the value of 2pq.
We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.
In other words:

So, it is possible to find
:

Now, there are two alleles in the population, so the following will be true:

It is possible to find q (the frequency of allele r) and p (the frequency of allele p):

Therefore:

Now, the frequency of heterozygotes or 2pq is:

Answer:
Protein containing food like meat, egg and chicken etc is the muscle building food.
Explanation: Protein containing food such as meat is the food substance that contains the nutritive materials which helps in the build of muscles in the human body , but does not contain the macromolecules that provides quick energy. Meat which is a good source of protein and we know that protein is the main nutrient which is responsible for the building of muscles in the human body.
