the adductor
the mussel of the clam keeps the shell together. But they can open it if the want.

The two halves of a DNA double helix are held together by hydrogen bonds between complementary nitrogenous bases. Adenine pairs with thymine and guanine pairs with cytosine. This base pairing allows for the specificity and stability of the DNA molecule.
posterior and anterior adductor muscles
An animal with a shell composed of two parts hinged together would be a bivalve, such as a mussel, clam, or oyster. Bivalves have two symmetrical shell halves that are connected by a hinge ligament, allowing the shell to open and close for protection and feeding. Oysters are filter feeders that play important roles in aquatic ecosystems.
The hinge ligament is a flexible structure that connects the two halves (valves) of a clam shell at the hinge. It acts as a spring to allow the shell to open and close. When the adductor muscles relax, the hinge ligament helps the clam's shell to open.
One example: Together , the two halves made one whole apple .
The heart is nestled between the digestive gland, and the 'muscle' (two parts, fast mucle, closes shell quickly, and the slow muscle, which holds the shell together for long periods of time.)
The umbo on a clam is the oldest part of the shell and can typically be found at the hinge of the two shell halves, closest to where they join together. It is usually more elevated and centrally located compared to the rest of the shell. Observing the position of the umbo can help determine the age and growth pattern of the clam.

There is two main purposes of the body shell. It keeps the car together. It also keeps the body rigid in the event of a car crash.
