Explanation:
Detailed explanation-1: -The bacterial cell replicates (180/20= 9) i.e., 9 times in 3 hours. So, the full amount of numbers of bacteria produced after 3 hours are 512 cells. Hence, the correct answer is option (C).
Detailed explanation-2: -One “trial” takes 20 minutes. So, after 3 hours, there have been: 60⋅320=9 trials. Therefore, there will be 29=512 bacteria.
Detailed explanation-3: -So, 1 bacterium can multiply to 2 in 20 minutes, 4 in 40 minutes, and so on.
Detailed explanation-4: -Under optimum condition Bacterial cells divide once in 20 minutes by binary fission.
