Some species of bacteria are harmful. Antibiotics are chemicals that kill bacteria. Some bacteria are resistant to antibiotics and are not killed by these chemicals. Over time, the resistant bacteria can reproduce and create populations that are not affected by antibiotics. The graphs below show the results of a controlled experiment that measured the population of one species of bacteria that had been grown in four containers under identical conditions. Different antibiotics were added to three of the four containers. Which conclusion about this species of bacteria is best supported by the information in the graphs?(picture below)1) Antibiotic A continuously slowed the growth.2) Antibiotic B was least effective in controlling the growth.3) Antibiotic C was most effective in controlling the growth.4) Antibiotics A and B slowed the growth. |
