Answer: D. geographic isolation and reproductive isolation

Speciation can be defined as a evolutionary process by which a new species develop from a parent species. It occurs when the members of the species becomes reproductively isolated and physically get separated due to geographical barriers. In allopatric speciation, the ancestral population evolve into a new species due to geographical barriers like river which separate the two populations of the same species apart. In sympatric speciation, the ancestral population evolve into a new species due to the reproductive and behavioral isolation. This is due to the fact that the members of the two species becomes incapable of inbreeding.

The diagram shows several structures located within a cell.

MakcuM [25]

Answer:

In the diagram, both structure B and C are fragments of DNA, which are found within structure A -which is a chromosome- so the statement that best describes the relationship is structures B and C are located within Structure A and code for inherited traits (option a).

Explanation:

Chromosomes are structures, present in cells during cell division, each consisting of one DNA molecule. Each fragment of the DNA molecule within a chromosome represents a gene, which contains the information needed to determine a trait in an individual.

According to the diagram (image), the DNA fragments B and C are genes that are found within structure A, the chromosome, and determine inheritable traits.
