4 Characteristics of Phylum Chordata correct answers Notochord, Dorsal tubular nerve cord, Pharyngeal gill slits, Postanal tail Notochord correct answers gives phylum chordata its name, is present in all embryos, and may be present or absent/reduced in adults. Dorsal tubular nerve cord correct answers A dorsal, hollow, ectodermal nerve cord typically forms by an infolding of the ectoderm tissue, which then pinches off and becomes surrounded by mesoderm Pharyngeal gill slits correct answ...

5 chordate characteristics correct answers 1. Notochord (replaced by vertebral column in vertebrates) 2. Dorsal (hollow) nerve cord 3. Pharyngeal slits 4. Post-anal tail 5. Endostyle Notochord correct answers sits below the dorsal hollow nerve cord, can bend side to side but cannot be compressed, helps with movement (especially swimming) Pharyngeal slits correct answers A gill structure in the pharynx that allows for filtration of water and food from the environment Endostyle correc...

All chordates must have these structures at some time in their development correct answers notochord, dorsal tubular nerve cord, pharyngeal pouches or slits, and post-anal tail notochord correct answers a stiff, but flexible rod of connective tissue extending lengthwise and dorsal to the digestive tract; is an axis for muscle attachment; in higher vertebrates it is converted in the adult to the vertebral column dorsal tubular nerve cor correct answers anterior end becomes brain, the rest i...

notochord correct answers the characteristic from which the phylum derives its name (means back-cord); a rodlike, semirigid body or fluid-engorged cells enclosed by a fibrous sheath extending the entire length of the body monophyletic correct answers groups that contain all known descendants of a single common ancestor paraphyletic correct answers groups (like reptiles) that do not contain the descendants of their most recent common ancestor Somites correct answers a series of cartilagi...

1. Mantle - A sheath of tissue surrounding the organs of a mollusk, producing the mollusk's shell and performing respiration. 2. Radula - An organ covered with hundreds of small teeth used for scraping food into the mouths of mollusks. 3. Chitin - A derivative of carbohydrates that provides both flexibility and support. 4. Molting - The process of shedding an exoskeleton and replacing it with a new one. 5. Cephalothorax - The anterior part of an arthropod body, consisting of a head and ...
