Question

bacterial contamination can spread quickly because if the conditions are right, bacteria can multiply in ______. options: 10 to 20 seconds, 10 to 20 minutes, 10 to 20 hours, 10 to 20 days (with selection dots for each option)

Explanation:

Bacterial multiplication under favorable conditions (like proper temperature, moisture, nutrients) typically occurs over minutes. Bacteria reproduce via binary fission, and a common time frame for their multiplication (doubling) is around 10 - 20 minutes in optimal environments. Seconds are too fast for most bacteria, hours or days are slower than typical active multiplication rates in good conditions.

Answer:

B. 10 to 20 minutes
