<h2><u>Answer</u> :</h2>
The correct option is A. If a dominant allele is present, the recessive allele won’t be seen.
The dominant allele is the one which appear, and the recessive one isn't shown.
For example - If a person has 2 alleles of eye colour as B ( black ) and b ( brown ), in which black is dominant and the brown one is recessive, then the person will have black eye colour because only dominant allele shows its characteristics.

Answer:
Nature
Explanation:
Because erosion happens in the nature.
Answer: DNA ligase.
Explanation:
Polymerase chain reaction is a technique used in molecular biology by scientists to make several copies of a DNA sample which enable them to take a smaller portions of it and expand it for more detailed study.
PCR mixture is premixed and contain thermostable DNA polymerase, oligonucleotides primer, four deoxynucleodide triphosphates, Magnesium chlorides, a propietary buffer.
Answer:
Option C) Feedback inhibition
Feedback inhibition is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step in the pathway.
Explanation:
Feedback inhibition is a regulatory mechanism in which a biochemical pathway is regulated by the amount of the product that the pathway produces. Thus, it is also known as end-point inhibition.
For example:
The accumulation of ATP inhibits the action of phosphofructokinase, the enzyme that catalyzes the rate-limiting step of glycolysis
