This means that they rely on external sources of heat to regulate their body temperature, unlike warm-blooded animals which can regulate their body temperature internally. Out of the options given, the only animal that is cold-blooded is the lizard. This is because lizards are ectothermic and depend on the environment to regulate their body temperature. Cats, whales, birds, and dogs are all warm-blooded animals, also known as endothermic animals. This means they can regulate their body temperature internally, which gives them the ability to maintain a constant body temperature even in varying environmental conditions. In conclusion, the correct option for this question is B, lizard. To learn more about the differences between cold-blooded and warm-blooded animals, please refer to your Biology textbook.
