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.

PLEASE ANSWER QUICK ;(
Neko [114]

Answer:

The correct answer is A. Since the Earth has a tilted angle of 23.5 degrees as it moves around the sun, the amount of sunlight that is received by the hemispheres vary from time to time. This is mainly responsible for the changes in the temperature and daylight hours, which are the indicators of the changes in seasons.

In this case, when one hemisphere of the Earth is tilted toward the sun, it receives more sunlight than the other end. Therefore, this region experiences summer, wherein the daylight is longer and the temperature is warmer
