Answer 25

Exocytosis

Question 26

The variable that is different between the control group and the experimental group

Answer 26

Manipulated variable

Question 27

The variable that we observe and measure as part of the experiment

Answer 27

Responding variable

Question 28

Group that is not changed from the normal circumstances

Answer 28

Control group

Question 29

Group operates with the experimental conditions or the new different conditions

Answer 29

Experimental group

Photosynthesis equation

Answer 30

CO2 + H2O + NRG(light) == O2 + CHO

Question 31

Cellular respiration

Answer 31

CHO + O2 == ATP(light) + H2O +CO2
