Question

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

d. graph the following information in a line graph. label and number the x and y - axis appropriately.

temperature	0	20	30	40	50	60	70

Explanation:

1. The independent variable is the one that is manipulated or changed in an experiment. Here, temperature is being changed, so it is the independent variable.
2. The dependent variable is the one that is measured and depends on the independent variable. Enzyme activity is being measured and is affected by temperature, so it is the dependent variable.
3. An appropriate title should summarize the relationship between the two variables. A title like "Effect of Temperature on Enzyme Activity" would be suitable.

Answer:

1. Independent variable: Temperature
2. Dependent variable: Enzyme Activity
3. Appropriate title: "Effect of Temperature on Enzyme Activity"
