Hello llockard,
The answer is <em>pe</em><em>t</em><em>roleum.</em><em>.</em><em>.</em><em> </em>It is because trees, water, plants, natural gas can take only 2 - 31 years to be made again... BUT, in case of petroleum, it takes nearly 100000 years, which is impossible for any human to live that much years... So, use petroleum carefully....

Cells are small because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume.
Hope this helps!
Light is an example of an abiotic factor. its also a major energy source
Answer:
B) Krebs cycle (citric acid cycle)
Explanation:
Glycolysis breaks glucose into two pyruvate molecules. Pyruvate is decarboxylated into acetyl CoA and the reaction occurs in the matrix of mitochondria. In the mitochondrial matrix, acetyl CoA enters Kreb's cycle and is broken down into CO2 and H2O. For one molecule of acetyl CoA, two molecules of CO2 are released as a by-product. Therefore, out of three carbon atoms of pyruvate, two are released as CO2 during Kreb's cycle.
A is direct variation because the line does not curve and x and y are in a direct ratio
