Are Protostome and Deuterostomes only applicable to tripoblastic animals?Are Cnidarians even protostome or deuterostomes?
In vertebrates, what anatomical structure partially or completely replaces the notochord? 1.) lateral-line system
2.) cartilage or a bony skeleton
3.) endostyle
4.) dorsal hallow nerve cord
Describe the development of the notochord. Include the terms primitive pit, notochordal process, notochordal canal, neurenteric canal, notochordal plate, ectoderm, mesoderm, and endoderm in your descriptions. Include labeled diagrams in your description. With respect to the developing notochord, where is the cloacal membrane, allantois, embryonic ectoderm, embryonic endoderm, and embryonic mesoderm with reference to the developing notochord.
