Answer:
The ability of species of living beings to overproduce offspring
Explanation:
Darwin proposed that species have the ability to produce offspring at a rate that could cause a geometric increase in the population size. This is called biotic potential. The overproduction of offspring causes intraspecific competition for the limited available resources. Darwin reasoned that the overproduction of progeny leads to a struggle for existence between the individuals of a population. He observed that the struggle for existence does not allow the population size of species to grow geometrically.
Answer: C. Dead snake fossilizing underground.
A fossil fuel is the fuel that is formed by natural processes, such as anaerobic decomposition of dead plants and animals underground. These organisms and their remains remain deep inside the depth of numerous layers of soil resulting in fuel produced after millions of years. A carbon sink refers to a natural or artificial reservoir that stores and absorbs atmospheric carbon by physical and biological process. The formation of fossil fuel inside the earth is carbon sink.
Dead snake will be added as a matter on which biological activity called as decomposition will take place. The organic matter of dead snake will be decomposed by microbes in the soil. The organic matter being the source of carbon, after decomposition will become the reservoir of carbon in the form of fossil fuel.
Therefore, dead snake fossilizing underground is the example of carbon source becoming a carbon sink.

The situation that a new technology would be most likely to cause change in existing theory about cell is : D. The technology allows detection of a substance that could not be detected previously
Cell is incredibly small and we still hasn't 100% figured out their perfect mechanism yet. New technology might found the new substance that alter the cell's theory as a whole
hope this helps
The correct answer is: A) lactic acid.
During the exercise, muscle cells use anaerobic respiration in order to make enough energy in the form of ATP. Anaerobic respiration doesn’t require oxygen, but glucose is broken down to produce energy. Glucose is broken down to pyruvate in the process called glycolysis. Next step is convert of pyruvate into lactic acid (or lactate).
During the exercise, the oxygen level in muscle cells decreases, which results in anaerobic respiration of the cells.
