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.

I believe the answer is Cytosine
carbon cycle
Explanation:
It is because it moves carbon,a life sustaining element from the atmosphere and oceans into the organisms
Let's look BB and Bb
They both have the dominant trait which means they both have the same physical appearance (phenotype) , but while BB has both dominant and Bb has one dominant and one recessive that means that although Bb has the same phenotype as BB, it has a different genotype because it has a bit different genetic makeup
