    No, because growth requires energy. When an animal is hibernating, it does not eat anything, and it burns off stored fat to stay alive. Therefore they do not grow at that time. Bears can recycle urine into amino acids which they can use to grow muscles, but nevertheless they still lose weight during hibernation. Growth rings in the bones of animals that hibernate shows that growth stops during hibernation. In fact, scientists also find growth rings in the long bones of dinosaurs and pterosaurs. That is why they can tell that dinosaurs and pterosaurs are cold-blooded. If they are warm-blooded they will eat and stay active the entire year and their bones would continue to grow. Human bones do not show growth rings because we do not hibernate. Reptiles that hibernate, such as alligators, also show growth rings in their bones.

    I would say yes, but at a much slower rate. Cells have to reproduce before they die.
