True False Some cnidarians only have a polyp stage. True FalseImagine you come across a small worm. How can you determine whether it is a class Hirudinida or a turbellarian? Give two distinct differences between the two without naming the same structure/invisible features of each animal (e.g animal x has 2 wings, animal y has 4 wings are not distinct differences)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!
