If you used the same experimental design to compare the rates of respiration of a 25 g. reptile and a 25 g. mammal at 10oC, what results woul dyou expect?
resp higher in mammal because the reptile is a conformer and relies on the environment for its warmth. Whatever the environment is, thats what the reptile will adjust his metabolic to. However, the mammal has an internal mechanism to maintain body temperature. So, at low temps, they will increase body temp becasue they need to keep warm.
