Answer:
DNA rearrangment.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
DNA rearrangment can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Hence, the ability of an individual to produce over a million different antibody molecules doesn't require the use of over a million different genes; rather, this wide range of antibody production is due to deoxyribonucleic acid (DNA) rearrangment.

This amendment serves as the basis for the political freedoms of the United States, and freedom of the press plays a strong role in keeping democracy healthy.
Explanation:
Answer:
Mammals are more closely related to birds because they share a more recent common ancestor.
Explanation:
A tree diagram that represents hypothesised phylogenetic relationship illustrating evolutionary relationships among various entities (most often taxonomic groups) that are known to share a common ancestor.
An ancestors is one from whom a person is descended, whether on the father's or mother's side, at any distance of time; a progenitor; a forefather.
B. Mammals are more closely related to birds because they share a more recent common ancestor
