4. Identify which of the following are found in gastropods only, bivalves only, or both of molluscs, using the following key:
G Gastropods B -Bivalves G/B-Both gastropods and bivalves
--------------- One-plece univalive
---------------- Two-piece shell (bivalve)
---------------- Apex; as the animal grows, the successive whorls increase in size
---------------- Muscular foot for locomotion
---------------- Hump, or umbo, on the anterior end of the dorsal side of each shell valve
---------------- Head, characterized by presence of two tentacles, each with an eye and radula for rasping
--------------- Presence of adductor muscles hold shell together No head and radula
5. Why are cephalopods considered advanced molluscs?

a. Coelomates exhibiting bilateral symmetry.
b. Two-part head with a prostomium and periostomium.
c. Segmented body with fairly well-developed nervous system.
d. Visceral mass, which contains the circulatory, digestive, respiratory, and reproductive systems.
e. Fresh-water, marine, and terrestrial species.
What goes in the blank?
8. The ----------------------- reproductive systems region in the phylum Mollusca contains the respiratory, circulatory, and reproductive systems.
