Answer:
Mechanical digestion:Begins with chewing Involves the teeth and tongue
Chemical digestion: Breaks down starch, protein carbohydrates, fats, and nucleic acids. Salivary glands produce an important substance for this type
Requires pancreatic juices and enzymes produced by the wall of the small intestine
Explanation:
Mechanical digestion starts in the mouth, it involves the breaking down of food into smaller particles.
Chemical digestion involves the breaking down of food into nutrients component that can be absorbable and used by the body cells.
It begins when the food mix with saliva in the mouth.
Chemical digestion starts from the mouth as the food mixes with saliva, Carbohydrate is been digested in the mouth while protein digestion takes place in the stomach. The pancreas produces important enzyme needed for digestion in the stomach.
Answer:
Ridges = crust formation
Trenches = crust destruction
Explanation:
Mid-ocean ridges are areas of rifting where two tectonic plates are diverging from one another. Magma rises up through the rifts and forms mountain ranges. The largest is located in the middle of the Atlantic. Rifting creates new crust.
Deep-ocean trenches are formed at convergent plate boundaries where the more dense plate (usually the oceanic) subducts under the less dense (usually continental). Subduction destroys old crust and is often accompanied by volcanoes. They are common along the pacific rim.
