E) all of the above Answer: A Diff: 2 Type: MC Page Ref: Sec. 22.1 Skill: Conceptual 6) If motility is considered a characteristic of animals, why are stationary creatures like sponges and crinoids still considered to be animals? Answer: They have a larval stage that is motile so they meet the criterion of "animals are mobile" because at some point in their life cycle they are. These animals become sessile as adults.

B) concentration of sensory structures in the head. C) the ability to make rapid responses to external stimuli. D) evolutionary development of a net-like system of veins. E) development of eyes at the head end of the organism. Answer: B Diff: 1 Type: MC Page Ref: Sec. 22.2 Skill: Factual 9) One trend in the evolution of animals is the increase in the number of tissue (germ) layers that can be seen during embryonic development.
