(a)[4]
Explain how the experimental arrangement shown in Fig. 2.2 makes it possible to determine the respiration rate of woodlice.
(b)[1]
A student measured the rate of respiration of woodlice at $5\,^{\circ}\text{C}$ and at $20\,^{\circ}\text{C}$. Predict and explain how the respiration rate of woodlice at $5\,^{\circ}\text{C}$ compares with that at $20\,\circ\text{C}$.
