You measure CO2 change over time using a CO2 probe of the following plants:

a.    A plant that is growing very quickly

b.    A plant that is growing very slowly

However, strangely, you see that the mean CO2 change over time for plant (a) is -130ppmCO2/min/g, whereas the mean CO2 change over time for plant (b) is -10ppmCO2/min/g.

A.    Write a hypothesis based on the scenario above

B.    Come up with a set a methods to test your hypothesis
