Final answer:
Bacteria can grow rapidly under favorable conditions. They reproduce through binary fission, allowing a single bacterium to form a large colony in a short amount of time.
Step-by-step explanation:
Bacteria can grow rapidly under favorable conditions. They require food, water, and other growth requirements to reproduce. Bacteria are known for their ability to divide quickly through binary fission. For example, E. coli bacteria can form a colony of hundreds of bacteria in just a few hours. Bacterial doubling times vary, with some species doubling in as little as 20 minutes under optimal conditions.
