The answer would be secondary succession.

Primary succession happens before an ecosystem is established. In contrast to it, secondary succession happens after a disaster that destroys most of the species in the land.
In this case, the ecosystem is already established. The forest fire is the disasters that destroy the ecosystem, allowing the secondary succession.

We have given that The epithelial cells in the skin of an animal have 24 chromosomes

We have to find the number of chromosomes present in the gametes of this animal

We know that number of chromosomes present in the gametes is given by

\frac{number\ of\ chromosmes\ present\ in\ skin}{2}

So number of chromosomes in gametes =\frac{24}{2}=12chromosomes

The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.

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.
