A. Animals are heterotrophic by ingestion B. Animals produce gametes that are diploid C. Animals are multicellular eukaryotes D. Animals are capable of movement at some stage in their life cycle 5.________ Which statement concerning body symmetry is NOT correct? A. radial symmetry is useful because the animal can reach out in all directions B. the evolution of bilateral symmetry is accompanied by cephalization C. bilaterally symmetric animals are usually sessile (don’t move) D. in radial symmetry, two identical halves are obtained regardless of how the animal is sliced longitudinally E. asymmetrical animals have no body symmetry 6.________ In ___, the mouth develops at or near the blastopore A. gastrocoelomates B. blastocoelomates C. protostomes D. deuterostomes 7.________ Which of the following is NOT a characteristic of the sponges? A. if the cells of a sponge are broken off, they will spontaneously grow to a complete and functioning sponge B. sponges have three tissue layers C. sponges have an osculum, a larger opening in the upper body D. sponges are filter feeders E. sponges can reproduce sexually or asexually 8.________ Which of the following are NOT members of phylum Cnidaria? A. corals B. sponges C. sea anemones D. hydras E. jellyfish 9.________ Which of the following is NOT correct about cnidarians? A. the adult body is bilaterally symmetrical B. most are found in shallow coastal marine environments C. stinging cells contain threadlike nematocyst released to capture prey D. they can have a polyp or medusa body form 10.________ Mollusks share a three-part body plan consisting of A. a scolex, proglottids, and an anus B. a corona, stomach, and intestines C. a visceral mass, mantle, and foot D. eyespots, a digestive system, and a nervous system 11.________ Which of these is a bivalve? A. slug B. octopus C. earthworm D. snail E. oyster 12.________ Which of the listed organisms do not possess the necessary features to be classified as a member of phylum Mollusca? A. clams B. squids C. lobsters D. nautiluses E. snails 13.________ Which of the following is NOT a cephalopod (class Cephalopoda) A. scallop B. octopus C. squid D. nautilus E. cuttlefish 14.________ Earthworms possess both male and female organs on separate segments (hermaphroditic). Mating could be described as “parallel parking” in opposite directions, and cross-fertilizing. Given this information, which of the following is (are) true? A. this is evidence of a primitive state that is generally less efficient than separate sexes B. this is primarily to allow them to self-fertilize if no other worm is in their sector of soil C. this is an advantage since they can mate with any other earthworm of the same species that they encounter D. maintaining any system not clearly male or female is disadvantageous; the earthworm is trapped in an evolutionary dead end 15.________ Which of the following is NOT correct about members of phylum Annelida? A. their bodies have segmented partitions (septa) B. most utilize setae (bristles) to help in movement C. they have a closed circulatory system (hemolymph stays within vessels) D. they have a beak to tear prey apart 16.________Which of these statements is NOT correct about flatworms?
