Changes to body cells affect A. Gene activity

B. Individuals.

C. Cell division.

D. Offspring

I will give Brainliest for correct answer.

Cell Division. Read explanation

Explanation:

It wouldn't be any of the sex cells so that would take out gene activity and offpsring. The only thing that changes the somatic (body) cells would be the slowing of cell division which I would assume is the correct answer.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
