Final answer:
Binary fission is an asexual reproductive process used by bacteria that results in two genetically identical daughter cells, facilitating rapid population growth. Therefore correct option is B
Step-by-step explanation:
Binary fission is a form of reproduction used by Bacteria. It is a type of asexual reproduction where a parent cell divides into two genetically identical daughter cells. This process allows bacteria to reproduce very rapidly and can result in a substantial increase in population in a short amount of time. Under ideal conditions, populations of bacteria can double every 20 minutes, which is an adaptation to rapidly changing or unstable environments.
During binary fission, the bacterial chromosome replicates and the cell starts to enlarge. A new cell wall begins to form, eventually dividing the original cell into two new cells that each contain an identical chromosome. This simple and efficient reproductive strategy is a key reason for the successful proliferation of bacteria.
