One major function of a monosaccharide<span> is its use for energy within a living organism. Glucose is a commonly known carbohydrate that is metabolized within cells to create fuel. In the presence of oxygen, glucose breaks down into carbon dioxide and water, and energy is released as a byproduct.</span>
The α-amino group of many amino acids is transferred to α-ketoglutarate to form glutamate, which is then oxidatively deaminated to yield ammonium ion (NH4+).
Answer:
D. There was a single transition from aquatic to terrestrial habitats
Explanation:
Based on the molecular differences at the level of DNA sequence and inheritance, the molecular phylogenies show that all land plants are a monophyletic group. This is why it suggests a single transition from aquatic to terrestrial habitats occur.
I believe the answer to 11 is that multicellular organisms are made up of multiple cells and unicellular organisms are made up of one cell.
