Organisms that can adapt to changes in their environment are most likely to survive and reproduce, while those that cannot adapt

Answer:

The right approach will be "Natural selection".

Explanation:

Natural selection seems to be a mechanism that persists and reproduces populations of organisms that seem to be better suited to applications, however those that are somewhat properly equipped die away.
This demonstrates that organisms that really can respond to a given climate can rise in quantities and therefore will ultimately outperform certain species that are unable to respond significantly.

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.
