4. How are a penguin's flipper bones different from the bones in other birds' wings?​

Answer 1

Ответ:

A clear difference between penguins and other birds is their bone density. All birds have tubular bones, which makes their skeleton lighter and allows them to fly or run fast, while in penguins they are similar to the bones of mammals (dolphins and seals) and do not contain internal cavities.
