Answer 11

A written summary of completed research

Question 12

What were the treatments for the cellular respiration experiment?

Answer 12

Glucose, sucrose, lactose, lactose + lactase

Question 13

What were the independent variables of the cellular respiration experiment?

Answer 13

Time
Sugar solution

Question 14

What were the dependent variables of the cellular respiration experiment?

Answer 14

The respiration rate of yeast

Question 15

What controls were positive/negative for the cellular respiration experiment?

Answer 15

Lactose + lactase = positive control
Glucose = negative control

Question 16

How would we graph the change in CO2?

Answer 16

Line graph

Question 17

To compare the respiration rates, how would we graph the rates?

Answer 17

Bar graph

Question 18

What was the difference between the production of the Lactose and the Lactose + lactase?

Answer 18

Lactose + lactase had a higher respiration rate

Question 19

How do both experiments demonstrate how we can demonstrate metabolic processes that we otherwise cannot see at a cellular or molecular level?

Answer 19

We observed the change in the volume of liquid for cellular respiration

We observed the number of leaves that rose for the photosynthesis experiment

Question 20

What were the treatments of the photosynthesis experiment?

Answer 20

1. No CO2, sunlight
2. 60mM CO2, sunlight
3. 60mM CO2, no sunlight
4. Unknown concentration CO2, sunlight

Question 21

What were the independent variables of the photosynthesis experiment?

Answer 21

Time
Amount of CO2
Light conditions

Question 22

What were the dependent variables of the photosynthesis experiment?

Answer 22

Photosynthetic rate (oxygen being produced)

Question 23

What were the controls of the photosynthesis experiment? Positive/negative

Answer 23

Negative: #3: 60mM CO2, No sunlight
Positive: #2: 60mM CO2, sunlight

Question 24

How would we graph the change in O2 produced in the photosynthesis experiment?

Answer 24

Line graph

Question 25

How would we graph the photosynthetic rate between treatments?

Answer 25

Bar graph

Question 26

Which treatments showed the importance of all the external inputs required for photosynthesis?

Answer 26

The ones with the same amount of CO2 but different light conditions. The one without sunlight didn’t change, highlighting the importance of light in photosynthesis
