A.
chordate
chosen
A chordate is an animal belonging to the phylum Chordata, characterized at some stage of its life cycle by the presence of a notochord, a dorsal hollow nerve cord, pharyngeal slits, an endostyle or thyroid gland, and a post-anal tail.
-
B.
jawless vertebrate group
A jawless vertebrate group is a clade of primitive, fish-like chordates characterized by the absence of true jaws, typically possessing cartilaginous skeletons, paired gill pouches, and elongated, eel-like bodies.
-
C.
group of cartilaginous fishes
A group of cartilaginous fishes is a taxonomic class of jawed vertebrates whose skeletons are made primarily of cartilage rather than bone, including sharks, rays, skates, and chimaeras.
-
D.
opisthokont group
The opisthokont group is a broad clade of eukaryotic organisms, including animals, fungi, and their unicellular relatives, characterized by cells that ancestrally possessed a single posterior flagellum.
-
E.
lancelet
A lancelet is a small, fish-like marine invertebrate chordate that retains a notochord throughout life and serves as a model for understanding early vertebrate evolution.
- F. None of above.
