Test
f an animal has segments, bilateral symmetry, pharyngeal clefts, a post-anal tail, and
deuterostomes development, it must be a member of the __________.
A. Chordata
B. Arthropoda
C. Annelida
D. Mollusca
E. Platyhelminthes - answerA. Chordata - Chordates are deuterostomes that have four
anatomical structures appearing at some time in development: a notochord, a hollow
dorsal nerve cord, pharyngeal clefts, and a muscular post-anal tail.
Notes:
B. Arthropods are protostomes.
C. Annelids lack, for example, a post-anal tail.
D. Molluscs are protostomes.
E. Platyhelminthes (flatworms) lack, for example, pharyngeal gill clefts.
A __________ is a chordate but not a vertebrate.
A. shark
B. frog
C. lancelet
D. sea star
E. lamprey - answerC. lancelet - Lancelets are cephalochordates and, throughout their
life, retain the notochord as the primary support of the appendicular skeleton.
Notes:
A. Sharks have cartilaginous vertebrae.
B. Frogs are amphibians; amphibians are vertebrates.
D. Sea stars are echinoderms.
E. Lampreys have a cartilaginous tube around their notochord; they qualify as
vertebrates.
Which of the following chordate characteristics contributes most to the formation of your
ears?
A. pharyngeal slits or clefts
B. dorsal, hollow nerve cord
C. notochord
, D. muscular, post-anal tail
E. None of the listed responses is correct. - answerA. pharyngeal slits or clefts - In
mammals, derivatives of the pharyngeal slits contribute to the development of portions
of our ears.
Notes:
B. Although our ears have components of the nervous system, this is not the best
choice.
C. The notochord does not contribute to the ear.
D. This is the wrong end of the animal.
E. n/a
Which of the following chordate characteristics contributes most to suspension-feeding
devices in many invertebrate chordates?
A. pharyngeal slits or clefts
B. muscular, post-anal tail
C. dorsal, hollow nerve cord
D. notochord
E. None of the listed responses is correct - answerA. pharyngeal slits or clefts -
Derivatives of the pharyngeal slits contribute to suspension-feeding devices in many
invertebrate chordates.
Notes:
B. This is the wrong end of the animal.
C. Although there are nerves associated with these suspension-feeding devices, this is
not the best choice.
D. Although there are skeletal structures associated with these suspension-feeding
devices, this is not the best choice.
E. n/a
Which of the following pairs is NOT a correct match?
A. Chondrichthyes, great white shark
B. Osteichthyes, perch
C. Gnathostomata, hagfish
D. Mammalia, kangaroo
E. Aves, canary - answerC. Gnathostomata, hagfish - Gnathostomes are jawed
vertebrates. A hagfish is an agnathan, a jawless vertebrate.
Notes:
A. Sharks are cartilaginous fish.
B. A perch is a bony fish.
D. Marsupials are mammals.
E. A canary is a bird.
Which of the following can be found in vertebrates but NOT in lancelets and tunicates?
