A.) Stimuli and regulating protein agents stimulate cell division.
Explanation;
Cell division is the process that occurs in organisms where a individual cell divides into two or more daughter cells.
There are two major types of cell division, mitosis that takes place in the somatic cells and meiosis that takes place in the germ line cells.Cell division is regulated by both external factors and internal factors.
External factors include physical and chemical signals from metabolic pathways. Stimulation of cell division is by proteins called growth factors, which are most important in embryonic development and cell repair and wound healing.
