21. compare and contrast the body organization of a ponge to that of a flatworm.
A hollow tube that is closed at the bottom and open at the top, have bilateral symmetry and have senses in the head region.
22. infer the advantages of being able to reproduce sexually and asexually for animals like sponges,cnidarians, and flatworms.
23. list the types of food that sponges,hydras, and planarians eat. explain why each organism eats a different size of particle.
24. compare and cosntrast the medusa and polyp body forms of cnidarians.
25. infer why scientists think the medusa stage was the 1st stage of the cnidarian.
26. form a hypothesis about why cooking pork at high temperatures prevents harmful round worms from developing, in the uncooked meat.
27. predict what you can about the life of an organism that has no mouth or digestive system but has suckers and hooks on its head.
28.look at the photograph below.this animal escapes from predators by mimicry. where in nature would you find the animal in this photo?
