Answer: So food must be broken down into smaller molecules before it can be absorbed through the blood and transported to cells throughout the body.
Explanation:
Digestion in humans is the process by which food and drink are broken down into smaller parts so that the body can use them as a source of energy to form and maintain tissues. It starts in the mouth, when we chew and eat, that is called mechanical digestion. And it ends in the small intestine, that's called chemical digestion. Although the chemical process varies depending on the kind of food.
<u>So food must be broken down into smaller molecules before it can be absorbed through the blood and transported to cells throughout the body.</u> Then the polymers (large molecules such as carbohydrates, proteins or lipids) are degraded into the simpler components called monomers (monosaccharides, amino acids, glycerol and fatty acids). These monomers are the ones that the body can absorb for use, it cannot do so with large, complex molecules.

A
Convergent boundary occurs between tow colliding tectonic plates. The denser plate, usually the oceanic plate, is subducted underneath the less dense plate usually the continental plate
Explanation:
The pacific ring of fire is named so because of the frequency of volcanos and earthquakes in this region compared to the rest of the world. This region is home to 75% of all earth volcanos and 95% of earthquakes. These geological phenomenons occur with such frequency because this region sits on convergent boundary between several plates that are colliding; Pacific, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.
