retina.
A. Fission because the daughter cells are identical.
Small populations
In small population sizes, inbreeding, or mating between individuals with similar genetic makeup, is more likely to occur, thus perpetuating more common alleles to the point of fixation, thus decreasing genetic diversity.
Conduct heat, allow the formation of new molecules and the splitting of molecules
