Answer:
Carbohydrate digestion begins in the mouth, while protein digestion takes place in the stomach.
Explanation:
Salivary glands create saliva in the mouth that contains enzymes to convert carbohydrates into sugars.
The stomach lining's digestive glands also secrete enzymes that break down proteins into essential amino acids that the body requires to synthesize proteins.
Carbon pools are systems capable of storing and releasing carbon. Various processes shift carbon from one pool to another, with combustion being one example. When biomass and hydrocarbons are incinerated, it transforms carbon in the biosphere into carbon dioxide released into the atmosphere.
Example:
C3H8 + 5O2 → 3CO2 + 4H2O + heat.
The endosymbiotic theory provides an explanation for the evolution of chloroplasts and mitochondria within eukaryotic cells.
This hypothesis posits that eukaryotes developed through a mechanism in which different types of free-living prokaryotes were absorbed into larger prokaryotic cells, eventually transforming into chloroplasts, mitochondria, and other organelles.
It is an independent variable.
