Hi there im having difficulty with this question - could anyone help. This is the question:
Antibiotic drugs A and B have been tested for their potency against a certain strain of bacteria. The drugs were applied onto an agar plate containing the bacteria and after 12 hours two circles depleted of bacteria were observed where the drugs were applied. Drug A resulted in a circle with a diameter 17mm and drug B resulted in a larger circle with a 31mm diameter. The concentration of drug A was 80µM and the concentration of drug B was 17µM.
How much more potent is drug B compared to drug A?
... and the ones that won't
