explanation :
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. ... The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell.
Moisture – Bacteria need moisture in order to grow. ... Food – Food provides energy and nutrients for bacteria to grow. High risk foods particularly protein foods such as chicken and dairy products are rich in nutrients and moisture and so promote bacterial growth.
4 to 20 minutes
Why it matters: Bacteria are among the fastest reproducing organisms in the world, doubling every 4 to 20 minutes. Some fast-growing bacteria such as pathogenic strains
