3.39 understand how resistance to antibiotics can increase in bacterial populations, and appreciate how such an increase can lead to infections being difficult to control

antibiotics: a compound that kills/ inhibits the growth of bacteria.

- with the increase in antibiotic use, bacteria will undergo rare mutations to show variation.
- bacteria that develop antibiotic-resistant genes will survive.
- this bacteria will reproduce to pass the antibiotic-resistant gene to offspring that will inherit the same resistance.
- over time, the population of antibiotic-resistant bacteria increases, making it more difficult to combat bacteria growth.
- results in difficulty curing and controlling bacterial diseases.
