What are three methods that microorganisms can use to resist the effects of antibiotics and what are at least two ways that these microorganisms can acquire these resistance traits?

Microorganisms can resist antibiotics through mechanisms such as producing enzymes that inactivate the drug, altering their target sites to prevent the antibiotic from binding, and employing efflux pumps to expel the antibiotic from the cell. They can acquire these resistance traits through horizontal gene transfer, where genetic material is exchanged between bacteria (e.g., via plasmids or transformation), and through spontaneous mutations that occur during replication, leading to resistant strains.
