What variables did the researchers need to control so they could obtain values comparable to other studies of standard metabolic rate?

Question

Accepted Answer

∻Answer∻ ⚹ Researchers need to control several variables to obtain comparable values for standard metabolic rate (SMR). ⚹ ∻Solution∻ ‖ a ⋮ Temperature: The temperature at which the organisms are kept must be controlled and kept constant, as metabolic rates can vary with temperature. ‖ ‖ b ⋮ Oxygen availability: Ensure that there is a consistent and adequate supply of oxygen, as oxygen consumption is often measured to determine metabolic rate. ‖ ‖ c ⋮ Nutritional status: The animals should be in a post-absorptive state, meaning they have not eaten recently, to avoid measuring the increased metabolic rate due to digestion. ‖ ‖ d ⋮ Activity level: The organisms should be at rest and not experiencing stress or engaging in activity that could elevate their metabolic rate. ‖ ‖ e ⋮ Size and age of the organism: These should be similar among the specimens being studied, as size and age can affect metabolic rate. ‖ ‖ f ⋮ Time of day: Metabolic rates can fluctuate throughout the day, so measurements should be taken at the same time to reduce variability. ‖ ∻Key Concept∻ ⚹ Standard metabolic rate (SMR) is the energy expenditure of an organism at rest in a thermoneutral environment, in a post-absorptive state. ⚹ ∻Explanation∻ ⚹ To obtain accurate and comparable SMR values, researchers must control environmental and physiological variables that can influence metabolic rate. ⚹◊What is the equation for calculating standard metabolic rate in organisms?⍭ Generate me a similar question◊
