Choose the best answer.

What is the primary mechanism driving antibiotic resistance in bacteria?

How do bacteria develop resistance to antibiotics?

Why does the overuse of antibiotics contribute to resistance?

What role does horizontal gene transfer play in antibiotic resistance?

Which of the following is NOT a consequence of antibiotic resistance?

Which environment is most likely to foster the development of antibiotic-resistant bacteria?

What is one of the main risks associated with antibiotic-resistant bacteria in medical settings?

Genetic drift

Natural selection

Artificial selection

By evolving stronger immune systems

Through genetic mutations and horizontal gene transfer

By avoiding antibiotic exposure

It increases the mutation rate of all bacteria.

It kills resistant bacteria, allowing non-resistant bacteria to survive.

It eliminates susceptible bacteria, leaving behind resistant strains.

It allows bacteria to share resistance genes.

It stops bacteria from mutating.

It slows down bacterial reproduction.

Common infections becoming harder to treat

Increased effectiveness of antibiotics

Higher risks in medical procedures

A sterile laboratory

A hospital with frequent antibiotic use

A remote island with little human activity

They only affect animals and not humans.

They make surgeries and treatments more dangerous due to increased infection risks.

They make antibiotics work faster.
