A)are used differently: SMR is measured during exercise, while BMR is measured at rest.
B)are used to compare metabolic rate between hibernating and non-hibernating states.
C)are both measured across a wide range of temperatures for a given species.
D)are both standard measurements of mammals.
E)are both measured in animals in a resting and fasting state.

Question

Quizplus · Accepted Answer

Both SMR and BMR are measured in animals in a resting and fasting state. SMR is the metabolic rate measured during low-level activity or exercise, while BMR is the metabolic rate measured at complete rest. Both measurements are used to assess an animal's energy expenditure and metabolic efficiency. While they are similar, they are not interchangeable and cannot be directly compared.
