Many unicellular organisms reproduce by the process of:
A. fission.
B. ovulation.
C. regeneration.
D. nondisjunction.
Binary fission is a type of asexual reproduction whereby a cell (such as an Ameba) replicates its DNA and splits its DNA and cytoplasm equally. Regeneration is also a type of asexual reproduction but is performed by simple multicellular animals such as lobsters and flatworms. Ovulation is the release of an egg to be used in sexual reproduction and nondisjunction is when the chromosomes split unequally in sexual reproduction.
