A researcher is setting up an experiment to measure basal metabolic rate in prairie voles (Microtus ochrogaster-a small rodent). Which of the following would be the best set of conditions for the voles immediately before and during the measurement?
A) House the animals in a cage with plenty of food and water to avoid stress; conduct measurements in a warmer room than the room where housed.
B) House the animals in a cage with plenty of food and water to avoid stress; conduct measurements in a room the same temperature as the room where housed.
C) House the animals in a cage with no food for a few hours before measurement; conduct measurements in a colder room than the room where housed, and exercise the voles.
D) House the animals in a cage with no food for a few hours before measurement; conduct measurements in a room the same temperature as the room where housed.
