The following microbial death curves were collected from a variety of antimicrobial treatments used on different e. coli samples. arrange the graphs below in order of the effectiveness of these treatments. assume that the most effective treatment is the one that, for a particular population size, kills e. coli the fastest. overlap graphs that show samples subjected to similar treatments. rank from most effective treatment to least effective treatment. to rank items as equivalent, overlap them.
