Answer to Question 1

ANS: T
Chordates had many advantages to aid them in growing larger. The skull provided the ample
protection and cavity needed to house the brain, eyes, and other sensory organs. Information can be
found in the section Vertebrate Evolution Traces a Long and Diverse History.

Answer to Question 2

ANS: F
Cnidarians are radial symmetric in their body plan. They can be divided on multiple planes on a
centric axis and still remain symmetrical. They do not have a distinguished head region like a bilateral
organism. Information can be found in the section Invertebrates Are the Most Successful and Abundant
Animals.
