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
A
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.
C Topic: Concept 32.1
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

Application/Analysis665 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 D) heterotrophy E) both A and C
C Topic: Concept 32.1
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.
E Topic: Concept 32.1
Application/Analysis 6) What do animals as diverse as corals and monkeys have in common? A)body cavity between
body wall and digestive system B) number of embryonic tissue layers C) type of body symmetry D) presence of Hox

Knowledge/Comprehension 7) The Hox genes came to regulate each of the following in what sequence, from earliest
to most recent? 1. identity and position of paired appendages in protostome embryos 2. formation of water channels
in sponges 3. anterior-posterior orientation of segments in protostome embryos 4. positioning of tentacles in
cnidarians 5. anterior-posterior orientation in vertebrate embryos A) 4 1 3 2 5 B) 4 2 3 1 5 C) 4 2 5 3 1 D) 2 4 5 3 1 E) 2 4

Synthesis/Evaluation
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. C) the descendents of
these adults do not include a larval stage. D) metamorphosis can no longer occur among the descendents of such
adults. E) both C and D.
A Topic: Concept 32.1
Application/Analysis 9) The last common ancestor of all animals was probably a A) unicellular chytrid. B) unicellular
yeast. C) plant. D) multicellular fungus. E) flagellated protist.
