Answer 2

Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts.[1][2][3] The fission may be binary fission, in which a single entity produces two parts, or multiple fission, in which a single entity produces multiple parts.
