Observations and Conclusions


1. Look at the Table 1 and the black growth curve. If all bacteria reproduce in the same way as Staph aureus, why is Earth not overrun with bacteria? Explain.

2. How do antibiotics help the host body?


3. How is antibiotic resistance dangerous for the host body?


Answer Key — Mutations and Antibiotic Resistance in Staphylococcus Bacteria
