Answer 1

[AI-generated answer — Bot GPT 3.5]

No, not all vertebrates have seven vertebrae in their necks. The number of vertebrae in the neck, also known as cervical vertebrae, can vary among different vertebrate groups. For example, most mammals, including humans, typically have seven cervical vertebrae. However, some mammals like giraffes have more cervical vertebrae, usually around seven to nine, to support their long necks. Other vertebrates such as birds, reptiles, and amphibians can have varying numbers of cervical vertebrae depending on their species.
