Digestive juices break down food into the tiniest nutrient components. Proteins are broken down to amino acids; fats are broken down to fatty acids and glycerol; and carbohydrates are broken down into simple sugars for absorption of these vital nutrients. The animal diet needs carbohydrates, protein, and fat, as well as vitamins and inorganic components for nutritional balance. Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body.
Photosynthesis takes place in the chloroplast of the plant cell.
B- speed up the chemical reaction
The reason both of these are valid scientific hypotheses is because A) scientists with different educational backgrounds may put forth different hypotheses to explain the same data.
This approach in science is vital in making progress and has helped to explain many phenomena in the past. When scientists explain data using different approaches, they come to a more comprehensive conclusion.
