Question

arrange the stages of embryo development from earliest to latest. move the choices up or down to put them in order. the gill pouches begin to disappear in mammals and birds. the embryos have similar structures, like gill pouches and tails. the embryos grow larger, and gill pouches remain visible. the gill pouches fully disappear in land animals but remain in fish.

Explanation:

Embryonic development starts with similar structures in early - stage embryos. As development progresses, embryos grow and then gill - pouches start to disappear in non - fish species. First, embryos have similar structures like gill pouches and tails. Then they grow larger with gill pouches still visible. After that, gill pouches begin to disappear in mammals and birds. Finally, gill pouches fully disappear in land animals but remain in fish.

Answer:

1. The embryos have similar structures, like gill pouches and tails.
2. The embryos grow larger, and gill pouches remain visible.
3. The gill pouches begin to disappear in mammals and birds.
4. The gill pouches fully disappear in land animals but remain in fish.
