Answer:

In the given case, it can be concluded that very less amount of telomerase is being produced.

Explanation:

Terminal transferase or telomerase refers to a ribonucleoprotein that supplements a telomere repeat sequence to the 3 prime terminals of telomeres. A telomere is present at each terminal of the chromosomes found in the majority of eukaryotes. It helps in safeguarding the terminals of the chromosomes from destruction or from getting combined with the adjacent chromosomes.  

Telomerase has its own RNA molecule and works as a reverse transcriptase enzyme. Generally, telomerase is found active in gametes, in stem cells, and in the majority of cancer cells, however, it is generally present in low concentration or is absent in the majority of somatic cells. Thus, the decrease in the ends of the chromosomes suggests that the production of telomerase is taking place at low levels.

Answer:

Natural selection

Explanation:

According to  Darwin's theory, natural selection is the process by which individuals better adapted to their environments have more chances to survive and reproduce, and thereby their descendants will be better represented in the next generation. This mechanism exploits the existence of natural variation among members in the population which is used to select those individuals that are better adapted (i.e., with a higher adaptive fitness) for their environments. Natural selection is a key mechanism of evolution by which species change across time.
