Choose the list that correctly ranks metabolic rates per gram of body mass, from lowest to highest. view available hint(s) choose the list that correctly ranks metabolic rates per gram of body mass, from lowest to highest. gazelle, lion, elephant human, cat, mouse, salamander human, rabbit, snake fish, dog, mouse hummingbird, dog, mouse

Answer 1

The list that correctly ranks metabolic rates per gram of body mass, in order from lowest to highest is: Fish, dog, mouse.

Fish are ectotherms, which generally have lower metabolic rates than endotherms (mammals and birds); consequently dog and mouse are both mammals.

Furthermore, although dog and mouse are both mammals, a mouse is much smaller than a dog. This implies that a mouse would have a higher metabolic rate per gram of body mass than a dog.
