Final answer:

Definition of chemical digestion in the mouth, effects of force based on Newton's laws, and importance of the water cycle.


Explanation:

Chemical digestion is the process of breaking down food into simpler nutrients that can be absorbed by the body. In the mouth, digestion begins with the action of salivary amylase enzymes that break down starch into maltose.

Newton's laws describe the three effects of force: 1. An object at rest stays at rest or in motion with a constant velocity unless acted upon by a force. 2. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. 3. For every action, there is an equal and opposite reaction.

Water cycle importance includes maintaining ecosystems through precipitation, replenishing water sources, and regulating climate by distributing heat globally.
