The following diagram shows representative members of two classes of molluscus.The CORRECT identification of the type of symmetry found in I and II is:
Correct answer: B. Bilaterally Symmetrical, Bilaterally Symmetrical
- A. Bilaterally Symmetrical, Asymmetrical
- B. Bilaterally Symmetrical, Bilaterally Symmetrical
- C. Radially Symmetrical, Bilaterally Symmetrical
- D. Asymmetrical, Radially Symmetrical
