Trava [24]

Answer:

0.25%

Explanation:

20 people start the new population. So there are 20 genes or 40 alleles for the recessive disorder phenylketonuria. 2 out of 40 alleles are recessive for the condition hence frequency of the allele = 2/40 = 0.05

Frequency of the allele does not change when the population increases so it is in Hardy-Weinberg equilibrium. According to it, if q is the frequency of recessive allele, q² = frequency of the recessive condition

Here, q = 0.05 So,

q² = (0.05)² = 0.0025

In percentage, it is 100 * 0.0025 = 0.25%

Hence, incidence of phenylketonuria in the new population is 0.25%

Vlad [161]

Cellular respiration

Explanation:

The energy animals need for their life functions are released when their cells carry out cellular respiration.

Cellular respiration is a metabolic process by which living organisms breaks down organic molecules using oxygen  especially glucose to produce energy and gives off carbon dioxide and water in the process.

It is the reverse of photosynthesis.

During this process, chemical energy stored in food substances are released and converted to heat energy.

The process takes place in the mitochondria of a cell.
