A more recently developed cancer treatment is targeting telomerase activity. So the correct answer is b)stimulating telomerase activity.
A topic of ongoing attention is the use of telomeres and telomerase as potential targets for the treatment of cancer. The telomerase enzyme is in charge of maintaining the telomeres, which cover and safeguard the ends of chromosomes.
Cells lacking telomerase experience replicative senescence, a growth stop, after a certain number of cell divisions. Inactivating essential cell cycle checkpoints is the first step in the vast majority of malignancies to overcome replicative senescence. Once telomeres are critically short, telomerase expression is then increased.
It has been demonstrated that telomerase suppression causes telomere shortening in cancer cells. After enough cell divisions, this attrition might result in telomere uncapping and the activation of apoptosis.

Plants.
This is because they can produce their own food with light. They use the sunlight to produce food, water, carbon dioxide or other chemicals they need. They process is call Photosynthesis.
Hope this helped :)
Have a great day
Answer:
16
Explanation:
Cells multiply so if at 22 there are 2
at 44 there will be 4
at 66 there will be 8
at 88 there will be 16
An organism has 28 pairs of chromosomes in its diploid somatic cells. How many chromosomes are in its gametes?
diploid = 2n, haploid = n
2n = 28 pairs = 28×2 = 56, n = 28
gametes are haploid = n = 28 total chromosomes
