Explain antibiotic resistance abserved in bacteria in light of Darwin's Natural selectionTheory.

Explanation

Thie is also true for discase causing bacteria against which we use antibiotics or drugs to kill these bacteria. When a bacterial population encounters a particular antibiotic, those sensitive to it die. But some hacteria having mutations becomes resistant to the antibiotic. Such resistant bacteria survive and multiply quickly as the competing bacteria have died. Soon the resistance providing gencs become widespread and entire bacterial population becomes resistant.
