Yes, mammals have a 4chambered heart, while reptiles only have a 3chambered heart.
Yes, like any living mammal, they need oxygen to survive, therefore they breathe.
Two reasons. First, the general metabolic rate drops, which slows the resporatory rate and the need for oxygen. Second, cold water can dissolve more oxygen and carbon dioxide than warm water can, so respiration is more efficient.
False, the more oxygen you need the faster you will breathe.
Both are mammals, as both are warm blooded, need oxygen to survive, and give live birth.
Because when you work your muscles they need more oxygen, and to get more oxygen you need to breathe more often.
If you live in Melbourne, Australia. You do need a reptile licence.
No, larger mammals tend to have a higher affinity for oxygen. This is because larger animals have a greater need for oxygen due to their higher metabolic rates, so their bodies have adapted to efficiently utilize the available oxygen.
bcuz fishes need oxygen to survie in their wild p:
fish. if its a mammal it would have either be warm blooded,have hair,fur,or wool,give live birth,and breathe wit lungs
because you need more oxygen to be delivered to the muscle and more waste to the lungs. when you are exercising your muscles need oxygen so the blood stars pumping faster to get the oxygen to the muscles.
your body needs more oxygen to keep the heart going at a more steady pace.
beats faster
