Answer:

Protein is broken down into amino acids in the stomach

Explanation:

As you may already know, digestion is the biological process that allows the foods you eat to undergo chemical and physical changes that allow your body to absorb nutrients, minerals, amino acids and all the substances needed by your body.

Physical modifications are responsible for breaking down food into smaller pieces, basically. However, chemical changes are primarily responsible for transforming food into assimilable substances. An example of chemical transformation occurs when protein is broken down into amino acids in the stomach.

How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
