1. what is the independent variable?
2. what is the dependent variable?
3. what is an appropriate title?

Explanation:

1. The independent variable is the one that is manipulated or changed. Here, the number of days is being changed, so it is the independent variable.
2. The dependent variable depends on the independent variable. The number of bacteria changes based on the number of days, so it is the dependent variable.
3. An appropriate title should summarize the relationship between the two variables. "Number of Bacteria over Time" describes the data well.

Answer:

1. # of Days
2. # of Bacteria
3. Number of Bacteria over Time
