Answer:
Glucose
Explanation:
Glucose is produced during photosynthesis and it is oxidised during cellular respiration to produce ATP energy.
It's a decomposition reaction. It's a chemical reaction because one substance (H2O2) is breaking down and becoming 2 completely new substances (H2O and O2)
If the results of an experiment have different conclusions, something must have changed. these are called **variables**. if more than one variable is changed, the result would be different. because the total conclusion is different, it is a hypothesis, because it is not universally true.
