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.
This process is responsible for the increase in number of cells which occurs during normal growth and development, and when tissues are replaced following injury. Normal cell division is also the basis for asexual reproduction. Only one type of cell is involved, with no input from another individual. Because no new genetic material is introduced, there is no variation in the resulting offspring.
