a. You should take the minimum amount of antibiotics needed to feel better.

b. Antibiotics work on infections by both bacteria and viruses.

c. Farm animals are often given antibiotics even if they are not sick.

d. Antibiotic resistance cannot be prevented.

2. Put the steps of how antibiotic resistance develops in the correct order.

Below is a sequence of events. Place them in the order they should occur, number 1 being the first item. Select the step number from the drop down next to each item.

_Antibiotic resistant bacteria multiply with less competition and dominate the population.

_Most bacteria are susceptible, but some are resistant due to genetic variation in the population.

_Bacteria are exposed to antibiotic.

_Antibiotic resistant bacteria survive more often than susceptible bacteria.

Answer 1

Answer 1

Option d - Antibiotic resistance cannot be prevented

Antibiotic resistance can be delayed but cannot be fully prevented as bacteria exchange genetic materials with or without external stimulus of presence of antibiotic.

Answer 2

The following are the steps of development of antibiotic resistance in bacteria :

1. Bacteria are exposed to antibiotic.
2. Most bacteria are susceptible, but some are resistant due to genetic variation in the population.
3. Antibiotic resistant bacteria survive more often than susceptible bacteria.
4. Antibiotic resistant bacteria multiply with less competition and dominate the population.
