This zone is also used to designate base floodplains of lesser hazards, such as areas protected by levees. from 100-year flood, or shallow flooding areas with average depths of less than one foot or drainage areas less than 1. square mile.
Amitosis is also referred to as Binary fission or direct division. This type of division is employed by lower prokaryotes, not only for multiplication of cells but also for reproduction. In this context, a bacterial cell has been taken as an example of describe the process.
We have already discussed how the two main events of cellular reproduction are the copying of cellular components and the cleavage of the cell. These two events, copying and cleaving, represent the two larger phases of the cell cycle, interphase and Mitosis. Mitosis is the part of the cell cycle when the cell prepares for and completes cell division. During interphase, appropriate cellular components are copied. Interphase is also a time of checkpoints to make sure that the cell is ready to proceed into mitosis. Both of these two phases have further sub-divisions.
