Chapter 34, Problem 8IQ
Summary Introduction
To list: Several representatives, both extinct and living of archosaurs and lepidosaurs.
Introduction: A group of amniote tetrapods is called diapsids. It is characterized by two skull opening on each side. It means two arches by which muscles of jaw is passed. It is very diverse and it includes snakes, crocodiles, tuatara, lizards, birds, and turtles. However, some diapsids lost either both holes or one hole or has skull that is restructured heavily, they are still categorized based on their ancestry.

Within the subphylum Urochordata is a group called the appendicularians (or larvaceans; class Appendicularia). This relatively obscure group of organisms plays an important role in the global carbon cycle and other biogeochemical processes in the ocean. Use library and Internet resources to research the natural history of these unique invertebrate chordates. What do they eat? How do they capture food?
Amphioxus long has been of interest to zoologists searching for a vertebrate ancestor. Explain why amphioxus captured such interest and why it no longer is considered to resemble closely the direct ancestor of the vertebrates.

- Amphioxus long has been of interest to zoologists searching for a vertebrate ancestor. Explain why amphioxus captured such interest and how it is different from the hypothesized most recent common ancestor of all vertebrates.arrow_forwardWhich of the following is the correct classification for this chordate animal: This vertebrate starts its life cycle in the water in a form without legs. the adult form is a tetrapod and lives mostly on land. These animals do not have a tail and they are specialized for movement like jumping to capture prey. Question 26 options: a) Birds b) Cephalochordata c) Monotreme d) Class Chondrichthyes e) Urodela / Salamanders f) Anura / Frogs g) Eutharia h) Reptiles (non avian) i) Marsupial j) Superclass Agnatha k) Class Osteichthyesarrow_forwardWhich of the following is the correct classification for the following chordate animal: This animal has a skeleton made of bone. Most modern day fish are in this group. They use gills to breathe and have a swim bladder to help control buoyancy. They also have a lateral line to detect vibrations in the water. Question 29 options: a) Superclass Agnatha b) Urodela / Salamanders c) Anura / Frogs d) Marsupial e) Class Osteichthyes f) Reptiles (non avian) g) Monotreme h) Birds i) Cephalochordata j) Eutharia k) Class Chondrichthyesarrow_forward
- Which of the following is the correct classification for the following chordate animal: These animals are chordates but do not have a backbone or cranium. They have all five features of chordates into adulthood. The notochord extends into its head. Question 27 options: a) Birds b) Anura / Frogs c) Urodela / Salamanders d) Superclass Agnatha e) Monotreme f) Eutharia g) Reptiles (non avian) h) Class Chondrichthyes i) Cephalochordata j) Class Osteichthyes k) Marsupialarrow_forwardPharyngeal slits are which of the following? Question 24 options: a) Openings in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth. b) Elongations of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates. c) Flexible, rod-shaped structures that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species. d) Tissues that produces thyroid type hormones. e) Hollow tubes that develops from ectoderm. Develops into the central nervous system.arrow_forwardOsteostracans are not included in the Gnathostome clade because [ Select ] ["They have heterocercal tails", "They lack jaws", "They have odontodes (true bone)"] . But they are considered the sister species of Gnathostomes because [ Select ] ["They have jaws", "They have odontodes (true bone)", "They have heterocercal tails"] and [ Select ] ["They have pectoral and pelvic fins", "They have pelvic fins only", "They have pectoral fins only"]arrow_forward
