검증된 단계별 안내1
Understand the term 'endothermy': Endothermy refers to the ability of an organism to maintain a stable internal body temperature through metabolic activity, regardless of external environmental conditions.
Identify the characteristics of birds: Birds are known for having feathers, being warm-blooded (endothermic), and having a high metabolic rate.
Identify the characteristics of mammals: Mammals are characterized by having hair or fur, being warm-blooded (endothermic), and producing milk to feed their young.
Compare the shared characteristics: Both birds and mammals are endothermic, meaning they can regulate their body temperature internally.
Conclude that endothermy is the shared characteristic between birds and mammals, as both groups maintain a constant body temperature through internal metabolic processes.
