Explanation:
When antibiotics attacks a bacteria first the growth of bacteria is stopped and the bacteria will become unable to divide and spread throughout the body via the bloodstream and aortic arteries. An antibiotics' main job is to stop the growth of bacteria and other foreign entities inside our body, such as a virus, fungal spore, parasites, and other dangerous and potentially deadly protozoa, so as to prevent the body from harm that may be fatal.
On cellular level, antibiotics chemically damage the bacteria or targeted organism's DNA and alter it in such a way that they will become unable to divide any further and thus become unable to reproduce and eventually die off as the white blood cells engulf the decaying organism's body, so it doesn't become dangerous.
