Answer to Question 1

ANS: D
Sharks have sensitive organs arrayed in lines under the surface of their skin that detect vibrations in the
water. This and their sense of smell are important in the hunting of prey. Prey is mostly comprised of
fish and marine mammals. Information can be found in the section Fishes Are Earth's Most Abundant
and Successful Vertebrates



Answer to Question 2

ANS: A
Cnidoblasts are the stinging cells on the tentacles of cnidarians. The tentacles then usher prey towards
the mouth. Information can be found in the section Invertebrates Are the Most Successful and
Abundant Animals.
