Answer:
D
Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
B. Green
Chlorophyll is found in and around the photosystems embedded in the thylakoid membrane of the chloroplasts.
The chloroplasts are organelles found in eukaryotic algae. The chloroplasts in eukaryotic celss are contained in the cytoplasm together with other organelles.
<span>Since the chlorophyll is insided the chloroplast which is inside the cytoplasm, it is safe to say that the chlorophyll of the green algae is spread throughout the cytoplasm of its cells.</span>
Atoms, molecules, cell membranes, then cell (in order from smallest to biggest).
The correct answer is option B, that is, functional group.
A functional group refers to a part of a molecule, which is a classified/recognizable group of bound atoms. The functional group provides the molecule with its characteristics, in spite of what molecule comprises it, they are the centers of chemical reactivity. The functional groups in a molecule require to be determined when naming.
