Which statement is true about endothermy in mammals and birds?
a. They both inherited this trait from a common ancestor.
b. Birds are more closely related to mammals than to reptiles.
c. Endothermy arose independently in these two lineages.
d. Birds are reptiles and all reptiles are ectothermic.

Accepted Answer

Hello everyone and welcome to today's video. So which of the following classes of organisms are endo thermic. Remember that endo thermic or what we call warm blooded organisms. And these organisms are able to regulate their own internal temperature via homeostasis. Now a very popular example of these warm blooded organisms are going to be mammals because they're mammals include humans. So humans do not need to for example be out in the sun in order to warm up or be in the shade to cool down. It definitely helps. But we have certain processes inside of our bodies that help with this. We're in the thermic, another very popular example is going to be AIDS and these are also warm blooded and have these mechanisms that allow it to regulate its internal temperature. They will also end the third make. However, reptiles are ecto thermic, they're not able to regulate their own internal temperature. They are cold blooded because they're cold blooded and they're not able to regulate their own internal temperatures. This is why this is why we see reptiles in the shed or son for long periods of time during the day. And this is to basically regulate their own internal temperature using these resources. So because of these answer choices, B and C. Are both going to be endo thermic and that is represented by answer choice. That is the final answer to the question and I really hope this video helped you
