CSEC Biology · May/June 2010 · Paper 2 · Question 1(d)

Humans also carry out other functions similar to that shown by the plant species represented at Figure 1, for example, respiration. In investigating respiration in a human being and a plant, explain how you would demonstrate that the process carried out by both organisms is the same.

This question uses a figure or table from the paper — you'll see it when you practise.
