The rate of oxygen consumption by a germinating seed follows the Q\(_{10}\) temperature coefficient: \(\text{Rate}_2 = \text{Rate}_1 \times Q_{10}^{(T_2-T_1)/10}\). At \(20^{\circ}\)C the measured O\(_2\) consumption rate is \(0.8\) mL min\(^{-1}\). When the temperature is raised to \(30^{\circ}\)C the rate increases by a factor of 2.5. (i) Determine the Q\(_{10}\) value. (ii) Using this Q\(_{10}\), calculate the expected O\(_2\) consumption rate at \(35^{\circ}\)C, giving your answer to two decimal places.

Answer Options

A. Q₁₀ = 2.0; O₂ consumption at 35°C = 2.80 mL min⁻¹
Correct Answer B. Q₁₀ = 2.5; O₂ consumption at 35°C = 3.16 mL min⁻¹
C. Q₁₀ = 3.0; O₂ consumption at 35°C = 3.80 mL min⁻¹
D. Q₁₀ = 2.5; O₂ consumption at 35°C = 2.95 mL min⁻¹
Correct Answer
B
Correct Option:
Q₁₀ = 2.5; O₂ consumption at 35°C = 3.16 mL min⁻¹
