1. The following questions or fill-in-the-blanks only refer to invertebrate animals covered In
lecture and lab (your textbook and mastering biology cover several more phyla)
Solution
phyla contains diploblastic animals : jellyfish phyla contains triploblastic animals: Tapeworm ,
nematodes phyla with radial symmetry : corals, anemones phyla with bilateral symmetry : snails
phyla with an open circulatory system: crustaceans or insects phyla with an close circulatory
system: Earthworm phyla that use cellular processes for circulation and respiration: Sponges
phyla contain protostome coelomates : octopus phyla contain deuterostome coelomates : starfish
phyla contain acoelomates : ribbon worms, tapeworms phyla that contain pseudocoelomates :
cockroach phyla contain animals with exoskeleton that must be molted: Insect or spider phyla
with calcium carbonate structure : sponge phyla with complete alimentary canals for digestion:
Honey bee
