Answer and Explanation: 1. The valves of a clam are the two cupped shells that form the clams hard outer covering These shells are joined by a single ligament. These valves act as a hard protective layer that prevents them from being easily consumed by predators such as octopi. The valve of a clam is characterized by a scar from the posterior ...

The term ...What kind of body symmetry does a clam have? Each valve of Nuculopsis (right drawing, “Bilateral symmetry (clam)”) is nearly a mirror image of the other, so that the plane of symmetry lies along the line at which the valves join, called the line of commissure. This is true of most clams. Brachiopods are quite different.Biology 18 Spring, 2008 1 Lab 5: Phylum Mollusca Objectives: Understand the taxonomic relationships and major features of mollusks Learn the external and internal anatomy of the clam and squid Understand the major advantages and limitations of the exoskeletons of mollusks in relation to the hydrostatic skeletons of worms and the endoskeletons ofThe Class Pelecypoda, meaning "hatchet foot," includes the bivalves, clams, oysters and mussels.

Radial symmetry is the arrangement of body parts around a central axis, like rays on a sun or pieces in a pie.

A body plan is a stable configuration of characters for a major taxonomic group, such as chordates or arthropods. Despite widespread casual reliance on the concept for guiding comparisons within and between groups, the nature of body plans as well as the biological causes underlying their evolution have remained elusive.

For a wide class of systems of differential equations, every internal symmetry comes from a first order generalized symmetry and, conversely, every first order generalized symmetry satisfying certain explicit contact conditions determines an internal symmetry. We analyze the contact conditions in detail, deducing powerful necessary conditions ...
