Biology, 8e (Campbell) Chapter 32 An Introduction to Animal Diversity Multiple-Choice Questions 1) Which of the following terms or structures is properly associated only with animals? A) Hox genes B) cell wall C) autotrophy D) sexual reproduction E) chitin Answer: A Topic: Concept 32.1 Skill: Knowledge/Comprehension 2) Both animals and fungi are heterotrophic. What distinguishes animal heterotrophy from fungal heterotrophy is that only animals derive their nutrition A) from organic matter. B) by preying on animals. C) by ingesting it. D) by consuming living, rather than dead, prey. E) by using enzymes to digest their food. Answer: C Topic: Concept 32.1 Skill: Knowledge/Comprehension 3) The larvae of some insects are merely small versions of the adult, whereas the larvae of other insects look completely different from adults, eat different foods, and may live in different habitats. Which of the following most directly favors the evolution of the latter, more radical, kind of metamorphosis? A) natural selection of sexually immature forms of insects B) changes in the homeobox genes governing early development C) the evolution of meiosis D) B and C only E) A, B, and C Answer: B Topic: Concept 32.1 Skill: Application/Analysis 4) Which of the following is (are) unique to animals? A) cells that have mitochondria B) the structural carbohydrate, chitin C) nervous conduction and muscular movement 1

D) heterotrophy E) both A and C Answer: C Topic: Concept 32.1 Skill: Knowledge/Comprehension 5) The number of legs an insect has, the number of vertebrae in a vertebral column, or the number of joints in a digit (such as a finger) are all strongly influenced by A) haploid genomes. B) introns within genes. C) heterotic genes. D) heterogeneous genes. E) Hox genes. Answer: E Topic: Concept 32.1 Skill: Application/Analysis 6) What do animals as diverse as corals and monkeys have in common?

8) In individual insects of some species, whole chromosomes that carry larval genes are eliminated from the genomes of somatic cells at the time of metamorphosis. A consequence of this occurrence is that A) we could not clone a larva from the somatic cells of such an adult insect. B) such species must reproduce only asexually.
