It's most likely a because plant,fish and turtles need water to survive nevermind just go for b lol :)
The cessation of telomerase activity as we age limits the number of times a cell can replicate. current research on telomerases is particularly useful in the fight against cancer. This is because, Cancer cells employ a mechanism that activates telomerases, which leads to uncontrolled cellular division.
The body's stages of life are intimately correlated with telomerase activity. During the development of the embryo, the enzyme is active. High telomerase activity, which allows cells to divide endlessly, is a characteristic of cancer cells. In 85–95 percent of malignancies, telomerase is active (3,4).

Answer:
It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. It is a vector-borne parasitic disease transmited by the Tse-tse fly.
Explanation:
African sleeping sickness, named human African trypanosomiasis, is a vector-borne parasitic disease transmited by the Tse-tse fly (that belongs to the Glossina genus). These flies can acquire the parasite by biting infected humans or animals.
The causative agent is a protozoan of the genus Trypanosoma,
It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. It can be Trypanosoma brucei gambiense or Trypanosoma brucei rhodesiense. Trypanosoma brucei gambiense has a prevalence of 98% of the reported cases, while Trypanosoma brucei gambiense accounts for the 2%.
First, crossing-over and the subsequent rearrangement of alleles on homologous chromosomes leads to gametes with a new mix of genetic material. Second, when the gametes fuse, new combinations of alleles result.
