All vertebrate embryos have tails.
All vertebrate embryos have tails. - no response given

All vertebrate embryos have legs.

Answer 1

The correct statement is: "All vertebrate embryos have tails."

During early stages of development, vertebrate embryos exhibit a tail structure, which is a common feature among them. This characteristic can be observed in the embryonic development of mammals, birds, reptiles, amphibians, and fish.

To clarify the other statements:
- Not all vertebrate embryos have ears; ear structures develop later in embryonic development.
- Not all vertebrate embryos have hair; hair is specific to mammals.
- Not all vertebrate embryos have legs; especially in early stages, many do not have limbs yet.

So, the statement regarding tails is the correct choice.
