Read each question carefully and answer to the best of your ability. Provide detailed explanations where requested.
1. Which of the following is the primary reason for the development of antibiotic resistance in bacteria?
Overuse and misuse of antibiotics
Eating organic foods
Regular hand washing
Vaccination programs
2. Which structure in bacteria is often targeted by antibiotics, and how can mutations in this structure lead to resistance?
Cell wall; mutations can prevent antibiotic binding
Flagella; mutations can make bacteria move faster
Capsule; mutations can make it more sticky
Nucleoid; mutations can increase DNA replication
3. Bacterial resistance occurs when bacteria develop the ability to the effects of antibiotics.
4. One common mechanism of resistance is the production of enzymes that the antibiotic molecule.
5. The transfer of resistance genes between bacteria is known as gene transfer.
6. Explain the concept of natural selection as it applies to the development of antibiotic resistance in bacteria.
7. Label the following parts of the bacterial cell that are relevant to antibiotic action or resistance:
a. Cell Wall:
b. Cell Membrane:
c. Ribosomes:
d. Plasmid:
8. All bacteria are harmful and cause disease.
True
False
9. Taking antibiotics when you have a viral infection will help you recover faster.
True
False
10. Discuss at least three strategies that can be implemented at individual or societal levels to combat the rise of antibiotic resistance.
