Answer: The correct answer is-

Choanozoa.

A phylogenetic tree is a representation of evolutionary relationship between different species. It is constructed on the basis of their similarities and differences in their morphological ( physical traits) as well as genetic characteristics.

Two species are said to be most closely related if they share most recent common ancestor. In other words, when two species are descended from a most recent common ancestor, they are said to be most closely related with each other.

In this question, Animals and Choanozoa share most recent common ancestor.

Thus, animals are most closely related to Choanozoa.

After the process of _______ occurs, each daughter cell receives an exact copy of the parent cell's DNA.
Alborosie

DNA replication

After the process of DNA replication occurs, each daughter cell receives an exact copy of the parent cell's DNA.

DNA replication is a biological process by which a DNA molecule divides to produce two copies of itself during cell division. DNA replication takes place in all living organisms. During DNA replication, an enzyme known as helicase separates the double helix structure of the DNA molecule into two separate strands which serve as templates for making the new strands of DNA.

What is the relationship between DNA, chromosomes, genes, alleles, dominant, recessive, and trait?
larisa86 [58]
Chromosomes are made of condensed coils of DNA. Genes are segments on a chromosome that carry the code for a specific trait. Alleles are contrasting forms of a gene. Dominant means that a particular trait will be visible. Recessive means that a trait will be hidden (unless it is paired with another recessive gene). A trait is how the gene is seen. For example, eye color is a trait.
