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

utes. This means that if 100 bacteria are left alone for 2 hours, they will multiply to become:
12,400 Bacteria
18,400 Bacteria
25,600 Bacteria
36,600 Bacteria

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.

Vinvika [58]
The mother may feel guilty about her child's condition because she may think that the child had that disease genetically from one or both of his or her parents. The mother may exhibit signs of self-blaming because she feels like it is her fault that her child is suffering from the disease. The healthcare practitioner should approach the mother in a biopsychosocial approach wherein the mother is allowed to vent out (catharsis), then the healthcare practitioner should make things clearer (educate), and then have the appropriate action given.
