Mechanical waves can be Longitudinal or Transverse.

Explanation: So... a mechanical wave is a kind of wave that is a oscillation of matter. Mechanical waves can also transfer energy. However, while it still can transfer over long distances, the wave is limited. it means that the oscillation material is limited. A mechanical wave can be a transverse wave or a longitudinal wave or a surface wave. but since there is only Longitudinal or Transverse that should be your answer.

A transverse wave, its a wave that particles move up and down.

A Longitudinal wave is a wave that moves back and forth.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
