Answer:
Antibiotic resistance is an act of evolution via natural selection. The antibiotic action is an environmental pressure: those bacteria which have mutation allowing them to survive and re-produce
Explanation:
A variation in the properties of an organism over a period of time is called evolution.
Antibiotic resistance can transpire naturally or due to progression.
This type of endurance occurs so that the bacteria can persist and proliferate in the changed conditions.
Fluoroquinolones (FQ) modify the enzymes like DNA gyrase and topoisomerase IV.
The bacteria in order to survive from this antibiotic adapted mechanism so that the use of antibiotics would not hinder their reproduction mode and hence they will be able to survive.
