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...

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...

CVA Final Exam (Answered) 2022 Graded A+ evolution changes in the genetic makeup of populations of animals through time - change in genetics eventually leads to changes in phenotype recapitulation similarities in embryonic developmental stages of different species is evidence that the embryos are repeating the developmental stages of the ancestors mosaic evolution parts of the body can change independent of others homology similarity in organs from different organisms as a result of i...
