Answer:
Vertebrates are members of the kingdom Animalia and the phylum Chordata . Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development. The deuterostomes, whose name translates as “second mouth,” consist of two major phyla: Echinodermata and Chordata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
Deuterostome phylogeny. All chordates are deuterostomes possessing a notochord at some stage of their life cycle.

Answer:
Appositive Phrase
Explanation:
Appositive Phrase
An appositive is a noun or a noun phrase that renames the noun next to it. It serves the purpose of adding information about another noun. For example, consider the phrase "The boy raced ahead to the finish line. " Adding an appositive noun phrase could result in "The boy, an avid sprinter, raced ahead to the finish line."
The sentence is still complete without the appositive. However, adding the appositive (an avid sprinter) presents more information about the other noun (boy).
Duty, in a way, contributed to the shallowness and failure of Ivan's life. Not because duty in itself is bad, but because it has become Ivan's only preoccupation, apart from pleasant life. Tolstoy's negative view of duty is seen in the second half of this sentence: "he considered his duty all things that were so designated by people in authority". So, we are talking about duty as Ivan sees it, and Ivan sees it as it was designated by people in authority. That means, Ivan structures his life and his priorities according to the view of those above him. His only ambition is to try and climb the social ladder. When he fails to do it, he is disappointed and has to find another obsession - of course, materialistic one. And that is the decoration of his new house. That's when he falls down and injures himself - so, indirectly, his materialism has cost him his health and, ultimately, his life.
