Any theory can be disproven. A theory is simply a hypothesis that has been accepted as generally true, however in the realm of science, anything can be disproven.
Answer: Soil forms from weathered rocks and organic material.
The rest of the statements are false. First, fertile soil usually forms in plains or lands with lower steepness of slope. Soil in steep slopes are prone to erosion.
The O-horizon is made of material derived from trees (i.e. leaves, pine needles), decomposed materials and humus.
Lastly, more living organisms in an area means more nutrients for the soil.

They both are formed through the attraction of atoms possessing opposite polarities. Hydrogen bonds is a relatively weak bond between two oppositely charged sides of two or more molecules and in an ionic bond, an atom gives away one or more electrons to another atom, which means the ionic bond is stronger.
Answer:
(A) Aerobic
Explanation:
Cellular respiration is the process of breaking down sugars (nutrients) and releasing energy. This can occur aerobically in the presence of oxygen and anearobically without the presence of oxygen. This happens in glycolysis pathway, where the resulting end product in the presence of oxygen is; energy in form of ATP, carbon dioxide and water. In the absence of oxygen the resulting by product of glycolysis is lactate without any energy release.
