Question

1. what is the dependent variable? 3. what is an appropriate title? 4. what was the average grade earned? d. graph the following information in a line graph. label and number the x and y - axis appropriately. temperature enzyme activity 0 0 20 10 30 15 40 20 50 8 60 5 70 0 1. what is the independent variable? 2. what is the dependent variable? 3. what is an appropriate title?

Explanation:

Step1: Identify independent variable

The variable that is being changed or controlled is the independent variable. Here, temperature is being changed, so temperature is the independent variable.

Step2: Identify dependent variable

The variable that depends on the independent variable is the dependent variable. Enzyme activity changes with temperature, so enzyme activity is the dependent variable.

Step3: Determine appropriate title

A title should summarize the relationship between the two variables. An appropriate title could be "Effect of Temperature on Enzyme Activity".

Answer:

1. Temperature
2. Enzyme Activity
3. Effect of Temperature on Enzyme Activity
