Question

An antibiotic is a drug prescribed to people who are sick due to a bacterial infection. Streptococcus bacteria may cause a throat infection in humans. An experiment was designed to test the effects of two different antibiotics, A and B, on samples of Streptococcus bacteria. The graphs below show the results of this experiment.





Describe how the graph for antibiotic B shows that it was the most successful in controlling the number of bacteria.

Answer 1

Answer:

Antibiotic B is the most successful in controlling the number of bacteria, since the number of bacteria in this graph shows to be decreasing while the others are in increasing increments resulting in an upsurge in the number of bacteria.
