Answer: C
Explanation: Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

<span>Cilia and flagella are made up of microtubules covered by
plasma membrane and they projection from the cell. Thus, cilia are flagella are
motile and designed to move substances over or around the cell and they can as
well move the cell itself. In eukaryotes, they are conserved in their polypeptide
composition, structure and function as motile and sensory organelles.</span>
the radiations that are used to treat cancers are of the gamma type. primarily emitted from cobalt-60 (a radioactive isotope). and it is more controlled than other radiation exposures. i.e. solar radiation which is not controlled.
hope that this helps.
