Question

1. what is the independent variable? label it on the correct axis.
2. what is the dependent variable? label it on the correct axis.
3. title the graph.
4. create a legend.
5. what conclusions could you draw about the data shown in this graph?

graph the following information in a line graph

temperature (°c)	enzyme activity a	enzyme activity b
10	5	13
20	15	19
30	20	22
40	24	29
50	29	32
60	50
70	70

Explanation:

Step1: Identify independent variable

The independent variable is the one that is being changed or controlled. Here, it is temperature as it is the factor we are manipulating to observe changes in enzyme activity. So, the independent variable is temperature and it should be labeled on the x - axis.

Step2: Identify dependent variable

The dependent variable is the one that is being measured. Here, the enzyme activity of Enzyme A and Enzyme B is being measured. So, the dependent variable is enzyme activity and it should be labeled on the y - axis.

Step3: Title the graph

A suitable title could be "Effect of Temperature on Enzyme Activity of Enzyme A and Enzyme B".

Step4: Create a legend

The legend should indicate which line represents Enzyme A and which represents Enzyme B. For example, "Blue line: Enzyme A, Red line: Enzyme B".

Step5: Draw conclusions

As the temperature increases from 0°C to 40°C, the activity of both Enzyme A and Enzyme B increases. After 40°C, the activity of both enzymes starts to decrease. Enzyme A has a higher activity than Enzyme B at most temperatures shown.

Answer:

1. Independent variable: Temperature, label on x - axis.
2. Dependent variable: Enzyme activity, label on y - axis.
3. Title: "Effect of Temperature on Enzyme Activity of Enzyme A and Enzyme B".
4. Legend: "Blue line: Enzyme A, Red line: Enzyme B".
5. Conclusions: As temperature increases from 0°C to 40°C, activity of both enzymes increases, after 40°C it decreases. Enzyme A has higher activity than Enzyme B at most temperatures.
