Due to the ionic bonding of the molecules that allow for the geometric/crystalline structure.
Answer:
bilateral symmetry
Explanation:
The mollusks are a group of animals that is one of the oldest in existence. This groups of animals has two primary characteristics that make them easily distinguishable from the other animal groups, one of them being that they are unsegmented, and the other that they are bilaterally symmetrical.

Examples of digestive enzymes are:
Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin, produced in the stomach.
Trypsin, produced in the pancreas.
Pancreatic lipase, produced in the pancreas.
Deoxyribonuclease and ribonuclease, produced in the pancreas.
One may also ask, what type of molecule are enzymes made from? proteins
One may also ask, what enzymes are found in the Oesophagus?
The esophagus produces no digestive enzymes but does produce mucous for lubrication. The acidic environment in the stomach stops the action of the amylase enzyme. , sucrases, and lactases, which are also present in the brush border of the small intestinal wall. Maltase breaks down maltose into glucose.
How is saliva produced in the mouth?
You make saliva when you chew. Sucking on a hard candy or cough drop helps you make saliva, too. The glands that make saliva are called salivary glands. The salivary glands sit inside each cheek, at the bottom of your mouth, and near your front teeth by the jaw bone.
