I would like to have a study guide for my biology exam coming up this week. Could you find the answers to these questions?

1. Does a clam have no body symmetry, bilateral symmetry, or radial symmetry?

2. Indicate each of the following organisms whether they are classified under the Porifera phylum, the Cnidarian phylum, the Nematode phylum, the platyhelminthes phylum, or the annelid phylum. Sponge...Hydra...Coral...Polyp....Medusa...

3. Indicate which phylum is being described for each out of the Poriferam cnidarian, nematode, platyhelminthes, or annelid.
Segmented round worms...Filter Feeder....Sessile....Stinging cells...Straight tube within a tube...Porous bodies...Smooth skinned round worm...Tentacles...Flat worms.
