You 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!

Using the examples from the animals you have studied in this lab, give the differences between the following phyla: Echinodermata and planaria Cnidaria and Porifera Annelida and Nematoda Cnidaria and Mollusca Echinodermata and Chordata 2. Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal? Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last? Name three characteristics or features in the phyla studied that you could tell are ancestral or primitive and three that you may call advance? Explain further?
