because they allow antibiotics to kill bacteria without killing host‚ or human‚ cells. Why can antibiotics kill bacteria without killing the host cells? • Bacteria cells are smaller than human cells and have a simpler structure. How do antibiotics kill bacteria? • Antibiotics kill bacteria by either preventing bacteria from making cell walls‚ preventing bacteria from making complete proteins‚ or damaging the plasma membrane.

Question: What antibiotics work best in preventing E. coli k12 from growing; amoxicillin‚ ampicillin‚ or ciprofloxacin? Hypothesis: If ciprofloxacin‚ an antibiotic‚ is added to petri dishes covered in live bacteria and left to sit for four to six days in an incubator at 37 degrees Celsius‚ then the petri dishes containing ciprofloxacin will have the largest zone of inhibition out of all of the other antibiotics tested because research shows that ciprofloxacin in one of the strongest antibiotic currently

This was also proven to be a danger for humans as widespread use of antibiotics results in breading super pathogens (drug resistant bacteria).Besides antibiotics there are also other toxic substances which are used to feed the animals on these farms. These toxins may be contaminated in animal tissues and
