Concept explainers
To explain: The name of the phylum to which humans belong to.
Concept introduction: Phylum Chordata includes the highly advanced organisms that are all deuterostomes with three main characteristic features: notochord, nerve cord, and gill slits.
To explain: The anatomical structure for which the phylum is named.
Concept introduction: Phylum Chordata includes the highly advanced organisms that are all deuterostomes with three main characteristic features: notochord, nerve cord, and gill slits. The notochord is present in the invertebrate–chordate species and appears during the embryonic development of the chordates. It later develops into another anatomical structure depending upon the adaptation of the chordate to the environment.
To explain: The location where the derivative of the anatomical structure is found.

- Which of the following is the correct classification for the following invertebrate animal: These animals are long and segmented and have no appendages. They are covered by a protective cuticle and have a closed circulatory system. Question 20 options: a) Phylum Echinodermata b) Phylum Mollusca, Class Bivalvia c) Phylum Chordata d) Phylum Annelida e) Phylum Platyhelminthes f) Phylum Arthropoda, subphylum Hexapoda g) Phylum Echinodermata Previous PageNext Pagearrow_forwardWhich of the following is the correct classification for the following invertebrate animal: This animal has a wedge shaped muscular "foot", and it is a filter feeder. This animal is covered by two shells connected by hinge ligaments. Question 22 options: a) Phylum Mollusca, Class Bivalvia b) Phylum Chordata c) Phylum Echinodermata d) Phylum Arthropoda, subphylum Hexapoda e) Phylum Platyhelminthes f) Phylum Echinodermata g) Phylum Annelidaarrow_forwardWhat are advantages and disadvantages of asymmetrical body plan in animals?arrow_forward
- Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features. 1) Symmetry: Asymmetrical, Radial, or Bilateral 2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic) 3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate 4) Developmental mode (if Coelomate): Protostome or Dueuterostome Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla. * Please answer 1) and 2) only. Reposting question for other two to be answered.arrow_forwardIn vertebrates, what anatomical structure partially or completely replaces the notochord? 1.) lateral-line system 2.) cartilage or a bony skeleton 3.) endostyle 4.) dorsal hallow nerve cordarrow_forward1 explain the meaning of the following characteristics of animals a)triploblastic b)bilateral symmetry c)segmentation d) acoelomate e)cephalisationarrow_forward
- The evolution of different body plans in animals has led to a wide diversity of species. For example, in Cnidaria (which includes jellyfish and corals) we see a radically different body plan compared to insects or birds. What significant evolutionary development is exhibited by insects and birds that is not present in Cnidaria? The development of bilateral symmetry and cephalization. The development of radial symmetry. The development of a calcified exoskeleton. The development of tentacles for capturing prey.arrow_forwardWhat are all the different body systems of different animals? Explain each body systems in 4-5 sentences.arrow_forwardWhich of the following is the correct classification for the following invertebrate animal: These animals have radial symmetry with 5 arms. They have an internal endoskeleton and a water vascular system connected to their tube feet for locomotion.
