Yes
A lamprey is a chordata. Lampreys belong to the subphylum Vertebrata within the phylum Chordata, as they have a notochord, dorsal nerve cord, and other characteristic features of chordates.
Dorsal means pertaining to the back, so a dorsal nerve cord is essentially a spinal cord; it's the never cord in the back. It connects the brain to all of the body below the head.
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
A dorsal, hollow nerve cord.
Yes.
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).

Dorsal.
yes because it is a vertebrate
No, these are specific to Chordates
Yes, frogs have a dorsal nerve cord that runs along the back of their body. This nerve cord is part of their central nervous system and plays a key role in coordinating their movements and responses to stimuli.
