Question

3. How does the misuse of antibiotics affect the evolution of disease-causing bacteria? Use the theory of natural selection to explain the growing resistance to antibiotics.​

Answer 1

Answer: Antibiotic resistance occurs due to natural selection. These bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation. Because of natural selection, they are learning to fight the antibiotics and spread. The bacteria becomes stronger and stronger.
