Answer 1

1. I would say cat because the bone structures look the most similar but I am not 100% sure.
2. All but the bird have five "fingers."
3. I'm not sure about this one.
4. Whale because they are both aquatic mammals and have flippers/fins.
5. All of the organisms have a common ancestor. Their bone structures of their arms are very similar.
