They constantly go through the cell cycle and they reproduce. Two ways cell reproductions are meiosis and mitosis. DNA duplicates itself. Cancer is incessantly receiving messages.

Explanation:

The evolution of human species in which one species transformed into another species evolves by a mechanism known as anagenesis.

The<em> Homo sapiens</em> evolved from<em> Homo erectus </em>where<em> Homo sapiens </em>overwrites the ancestral species and caused the species to become  extinct.

Thus, Option-C is the correct answer.

How does the fact that telomeres are long stretches of repeated nucleotides lessen the impact that somatic cells don’t have te
Cloud [144]

Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.

  • Telomeres are repetitive sections at the very ends of chromosomes that are present in a variety of eukaryotic species, including humans and unicellular protists.
  • Each round of DNA replication wears down a little portion of the telomeres, which serve as caps to safeguard the interior chromosomal regions.
  • Most somatic (body) cells do not typically have telomerase activity, but certain adult stem cells and germ cells—the cells that produce sperm and eggs—have.
  • Adult germ cells, tumor cells, and fetal tissues all contain telomerase. Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.
