Answer: The additional protection in the body of aerobic organisms are that they can fight with the ROS radicle formed in the body.

Explanation:

The aerobic organism use oxygen as a final electron acceptor. The aerobic organisms have enzymes in the body which helps in getting from the reactive oxygen species. These enzymes are superoxide dismutase, peroxidase and catalase.

Anaerobes are vulnerable to these ROS which is produced by their own metabolism. They do not contain the enzymes such as superoxide dismutase and catalase that can help them to survive in these conditions.

Hence, because of antioxidants the aerobic organism can survive in oxygen and anaerobes cannot.

One of the reasons bacteria can be so deadly is because they multiply very quickly. E. coli has a doubling time of around 15 min
Travka [436]

Answer:

The correct answer is - 25600 bacteria.

Explanation:

Bacteria can divide and produce double their population very quickly. As mentioned in the question bacteria multiply every 15 minutes to their double number. Finding the number of bacteria after 2 hours is simple mathematics. Two hours means 120 minutes and dividing it to 15. The result will be 8 which mean the bacteria double their colony 8 time so,

100×2 to the power 8 = 100 (initial number of bacteria)×2×2×2×2×2×2×2×2= 25600

Thus, the correct answer is option- 25600 bacteria.
