It also has many pores, or holes, that allow water to flow into it. Specialized cells within the organism take in food and oxygen from the water and deposit wastes back into the water. The organism then pumps the water into a central cavity and out through a hole in its top. The organism shown in the picture belongs to the A. phylum Mollusca. B. phylum Porifera. C. phylum Platyhelminthes. D. phylum Cnidaria. 2. Humans, birds, and fish all have a notochord that is replaced by a vertebral column as the body develops. These three groups of organisms belong to the phylum _______. A. Nematoda B. Annelida C. Chordata D. Echinodermata 3. Which of the following are disadvantages of the Aristotelian classification system? I. The system contained too many groups to be useful. II. The system did not show relatedness of organisms. III.

A. vascular B. nonvascular C. flowering D. seed-producing 5. Which of the following is present in both prokaryotic cells and eukaryotic cells?
