Fission is ____
A
fusing together
B
division
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to 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.

Detailed explanation-2: -Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm.

Detailed explanation-3: -Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism. Binary fission is different from mitosis because prokaryotic cells do not have a true nucleus like eukaryotes. Also, there is no mitotic spindle formation in the nucleus during binary fission.

Detailed explanation-4: -binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
