Step by step
Solved in 2 steps
- All molluscs, but the bivalves, are bilaterally symmetrical (True/False)?What is the function of the molluscan visceral mass? Secretes the shell Movement Houses gills Houses organsHow are pearls formed? Why are molluscs the only organisms to have this ability? Explain your answers by stating the parts of the mollusc that are involved in this process.
- A radula in a gastropod is a female reproductive structure A sharp, tooth like structure for killing prey a structure that aids in feeding a sense organ for detecting light Which choice correctly identifies the body plan of a Mollusc? radial symmetry bilateral symmetry asymmetry (no symmetry)The only members of Phylum Mollusca that have a radula are the gastropods (True/False)?Molluscs can seem extremely different yet they share several core features. Sketch, label, and explain at least 5 of these shared common features and then how each is MODIFIED in the following groups: Bivalvia, Gastropoda, Cephalopoda
