Do snapping turtles have a dorsal nerve cord notochord?
Yes it does...it is a vertebrate
Does a kangaroo have a dorsal nerve cord?
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
What is a hollow nerve cord?
The dorsal nerve cord is one of the embryonic features unique to chordates, along with a notochord, a post-anal tail and pharyngeal slits. It is a hollow cord dorsal to the notochord. It is formed from a part of the ectoderm that rolls, forming the hollow tube, compared to other animal phyla, which have solid, ventral tubes. The dorsal nerve cord is later modified into the brain and spinal cord. Dorsal nerve cord is mainly found in phylum Vertebrata. Dorsal means the "back" side, as opposed to the belly side (ventral).

What is a hallow nerve cord?
A dorsol hollow nerve cord is a major phylum in the Kingdom Animalia. A chordate is characterized by the presence of a dorsal notochord at some stage of development.
At some point in their lives all chordates have what characteristics?
All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.
Vertebrates belong to phylum chordata this means they have at some time in their life a?
dorsal notochord, dorsal nerve cord, pharangeal pouches, and post anal tail.
What are the four body parts of all chordates?
Notochord, Postanal Tail, Pharyngeal Slits, Dorsal hollow nerve cord
What are three structures that all chordates have in common?
Chordates are animals that comprise the vertebrates. The three structures that are present during their development are the notochord, a tubular nerve cord and gill slits leading into the pharynx.
The three things all chordates have?
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
What are the four characteristics present in the chordates?
The four specific characteristics of chordates are that they have a notochord, hollow nerve cord near the notochord, pharyngeal pouches, and an endostyle. Many of these characteristics disappear in invertebrate chordates when they reach adulthood. Most vertebrate chordates retain all four features, such as humans.
The notochord of vertebrates is replaced by a nerve cord when the animal becomes an adult?
No, the notochord and the nerve cord arise from different germ layers. The notochord is replaced by an ossified backbone, though there are still remnants between the vertebrae. The nerve cord, however, is protected by the ossified vertebral column.
