If two organisms of different species share more similar DNA sequences with each other than with other species, we can conclude that ________.
Answers
If two organisms of different species share more similar DNA sequences with each other than with other species, we can conclude that these two species are very closely related.
Anatomy and embryology, molecular biology, biogeography, and fossils all provide evidence for large-scale evolution (macroevolution).Different species with comparable architecture may be homologous (shared by ancestry) or analogous (shared due to similar selective pressures).The similarity of life's molecules is evidence that it shared an ancestor. The connections between different species can be discovered by comparing DNA sequences.Biogeography, the study of the geographical distribution of organisms, provides information on the origin and evolution of potential species.The presence of extinct species in the past and evidence of long-term evolutionary changes are both shown by fossils.Learn more about the Evidences of evolution with the help of the given link:

Answers
Answer:
The figure shows where mitosis occurs in the cell cycle
Explanation:
The strength in the figure is the figure shows where mitosis occurs in the cell cycle and the figure shows stem cell differentiation. Thus, option D is correct.
What is mitosis?
A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic process. The cell's contents are typically evenly divided into two daughter cells with identical genomes after mitosis.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.
Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.
Therefore, Mitosis occurs after G2 stage in the cell cycle.The strength in the figure is the figure shows where mitosis occurs in the cell cycle and the figure shows stem cell differentiation. Thus, option D is correct.
