If the Q₁₀ of the metabolic rate of an animal is 2,then A) the animal is better acclimatized to a cold environment than it would be if its Q₁₀ were 3. B) the animal is an ectotherm. C) the animal consumes half as much oxygen per hour at 20°C as it does at 30°C. D) the animal's metabolic rate is not at basal levels. E) the animal produces twice as much heat at 20°C as it does at 30°C.

Question

Quizplus · Accepted Answer

The Q₁₀ value indicates the effect of temperature on metabolic rate. A lower Q₁₀ means the animal can consume less oxygen and maintain its metabolic rate, indicating better adaptation to colder temperatures. Therefore, the animal would consume half as much oxygen per hour at 20°C as it would at 30°C (Choice C). The other options are incorrect because the Q₁₀ value does not indicate whether the animal is an ectotherm (Choice B), at basal levels (Choice D), or produces twice as much heat at 20°C as it does at 30°C (Choice E).
