Answer:
It represents the first stage in the chemical oxidation of glucose by a cell.
Explanation:
Glycolysis is the first stage of oxidation of glucose by the process of cellular respiration. Glycolysis includes the breakdown of one molecule of glucose into two molecules of pyruvate. Substrate level phosphorylation forms net 2 ATP molecules and the redox reactions of glycolysis uses NAD+ as an electron acceptor resulting in the formation of 2 NADH.
Therefore, one molecule of glucose obtains 2 pyruvate molecules, 2ATP and 2 NADH by glycolysis. The fate of pyruvate depends on the availability of oxygen. Citric acid cycle and oxidative phosphorylation are the next two stages of aerobic cellular respiration.
Answer:
- Autotrophs are usually defined as those that can prepare their own food by carrying out the process of photosynthesis, but heterotrophs cannot prepare their own food and are directly dependent on the autotrophs for food. Examples of autotrophs are plants and trees, and examples of heterotrophs are animals and human beings.
- Autotrophs are the lowest organisms in the trophic level, where they produce the food for the consumers (heterotrophs). On the other hand, the heterotrophs lie above the autotrophs and when they consume their food, they obtain only 10% of the energy, and the remaining energy is released into the environment.
- Autotrophs can make organic substances by the use of inorganic molecules, but heterotrophs cannot make these substances. They are only dependent on the molecules prepared by these autotrophs.
Thus, these are three of the facts regarding autotrophs and heterotrophs existing on earth that are true.

Explanation:
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f(x, y) parallel to the (x, y)-plane. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.
