How could morphological data alone lead biologists to group animals into erroneous evolutionary relationships?arrow_forwardWithin the subphylum Urochordata is a group called the appendicularians (or larvaceans; class Appendicularia). This relatively obscure group of organisms plays an important role in the global carbon cycle and other biogeochemical processes in the ocean.

- compare cnidarians to sponges and to the clade containing flatworms, mollusks, and annelids. What features are similar among these groups? What features are different?arrow_forwardA new group of echinoderms, the sea daisies, or concentricycloids, wasdiscovered in 1986. They are deep-water animals living on sunken wood.They are flat and round, looking very much like a small sea star withoutarms. They also lack a gut. Without ever having seen them, why do youthink they were classified as echinoderms, not as members of a new phylum? Do you have any hypotheses as to how they feed or move around?arrow_forwardYou are trying to identify a living organism which you are observing closely. Which one of the following would convince you that the organism is acoelomate? It responds to food by moving toward it. It is triploblastic. It has bilateral symmetry. It possesses sensory structures at its anterior end. Muscular activity of its digestive system distorts the body wall. The flatworms have a true coelom a pseudocoelom radial symmetry tissues derived from the three basic germ layers (i.e. they are triploblastic) need help with both questions for my HW please thank you!arrow_forward
