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.

Some animals have no gills when young, but then develop gills that grow larger as the
animal grows larger. What is the reason for this increase in gill size?
A) The young of these animals are much more active than the adult, which leads to a
higher BMR (basal metabolic rate) and, therefore, a higher need for oxygen.
B) Relative to their volume, the young have more surface area across which they can
transport all the oxygen they need.
C) The young have a higher basal metabolic rate.
D) Relative to their surface area, the young have more body volume in which they can
store oxygen for long periods of time.

B) relative to their volume, the young have more surface area across which
they can transport all the oxygen they need.
