Neco 2021 Biology Question 4

A practical investigation was carried out to study the effect of temperature on the rate of respiration in germinating beans. The set‑up consisted of a sealed 50 mL gas syringe attached to a container holding 10 germinating beans. The volume of CO₂ produced was recorded at 5‑minute intervals for 20 minutes at three different temperatures. Data recorded: Time (min) | CO₂ volume (mL) at 20 °C | CO₂ volume (mL) at 30 °C | CO₂ volume (mL) at 40 °C -----------|---------------------------|---------------------------|--------------------------- 0 | 0.0 | 0.0 | 0.0 5 | 0.8 | 1.2 | 1.6 10 | 1.6 | 2.4 | 3.2 15 | 2.4 | 3.6 | 4.8 20 | 3.2 | 4.8 | 6.4 Using the data above, answer the following questions:
