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...

Mollusca, Arthropoda, Chordata, Echinodermata, Cnidaria, Porifera correct answers Phyla found in the rocky intertidal By size: macrofauna are larger than 1mm and meifauna are less than 1mm correct answers How do scientists define macrofauna and meiofauna? Chlorophyta (green), rhodophyta (reds), phaeophyta (browns - fucoids and kelps) correct answers The 3 different divisions of macroalgae found on rocky shores Primary producers (micro and macroalgae), grazers (limpets, periwinkles, urch...

What do organisms in the phylum Chordata vary from? correct answers From small worm like animals to humans. All members of the phylum Chordata have what characteristics in common? correct answers A notochord(flexible supporting rod), a dorsal, hollow nerve cord, pharyngeal gill slits, and a post-anal tail. How how are these characteristics presented? correct answers These characteristics may not be obvious, or they may even be absent in some stages of the life history, but all are present ...

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...

Vertebrate Ancestors: 'Chordate' Origins, 'Vertebrae and 'Cephalization Who are the vertebrates? How many species? - "animals with backbones" - phylum chordata: --> notochord, segmentation, jointed appendages (via deutersotome development and endoskeleton, derived from coelom, body cavity and bilateral symmetry) - subphylum craniata --> have no column hyperoterti (notochord) - roughly 45'000 species - infraphylum vertebrata --> 42'000 species (5% life - less diverse/...

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...
