Explain how natural selection leads to antibiotic resistance in bacteria. Describe how, when antibiotics are used, most bacteria die but a few with natural variations survive. These surviving bacteria reproduce and pass their resistant features to the next generations. Over time, the population becomes mostly resistant, making the antibiotic less effective.
