Answer:
A new mutation
Explanation:
A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.
However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.
The answer would be survival of the fittest.
This metaphor, "<em>survival of the fittest</em>," was used by Herbert Spencer to explain <em>natural selection. </em>It is sometimes also referred to as the survival for existence. This phrase came from the Dawinian theory of evolution where he explains that all species are capable of producing many offsprings. However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment.
<em>
</em>This relates to your scenario in the sense that fish lay a lot of eggs in the beginning but not all of them would live to achieve maturity. This is because even as eggs, they have many predators and are exposed to other elements. The threat pushes on even if they are able to hatch and grow up.

</em>
Answer;
- In the interior of the protein in contact with non-polar side chains
Explanation;
-Amino acids are generally soluble in water and insoluble in non-polar organic solvents such as hydrocarbons. In water, the ionic attractions between the ions in the solid amino acid are replaced by strong attractions between polar water molecules and the zwitterions
-Leucine is a vital amino acid for the protein synthesis and various metabolic functions. It is an essential amino acid, which helps in regulating the blood-sugar levels, promotes the growth and the recovery of muscle and bone tissues, and also the production of the growth hormone.
yes B is the correct answer
D fashoo because it decrease
