2. Why is it important to take the entire course of antibiotics medicine even when you feel better?
___________________________________________________________________________________
3. Why are antibiotics not useful against viruses, parasites, or fungi?

4. Create a graph that shows the Reproduction Rate for a bacterium that reproduces every minute for a total of 10
minutes. Be sure to include a good title and good X and Y axes labels. Start the graph with 1 bacterium at time 0 and
stop after 10 minutes.
Graph the Reproduction Rate for each of the bacteria given in the data table provided. Start each graph with 1
bacterium at time 0. Draw your graphs in the templates below. Answer the questions in complete sentences.
1. How are the shapes of the 3 Reproduction Rate Graphs similar to each other?

2. What is different about the 3 Reproduction Rate Graphs?
___________________________________________________________________________________
3. How does changing the reproduction rate of bacteria change how the bacteria will reproduce?
___________________________________________________________________________________
4. Assume a bacterium can reproduce every minute; explain how the number of bacteria will be different from the
ones given above at 300 minutes.
