Another level of genetic variation is added by random fertilization , since we can't predict which sperm will fertilize a given egg.
<h3>What is fertilization?</h3>
A new individual organism or progeny is created when two gametes are fused during fertilization, often referred to as fertilization, impregnation, syngamy, and generative fertilization. The term "fertilization" is often used colloquially to refer to pre-gametic processes like pollination and insemination. The cycle of fertilization and development of new individuals is called sexual reproduction. In the process of vegetative fertilization, the haploid male gamete of an angiosperm fuses with two haploid polar nuclei to create a triploid main endosperm nucleus.

The right answer is C
In the anaerobic mode, the reduction of pyruvate to lactate or ethanol (fermentations) ensures the reoxidation of NADH to NAD + consumed during the oxidation of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate (reaction 6 of glycolysis). This regeneration of NAD + allows glycolysis to be maintained in the absence of oxygen.
In the aerobic mode, NAD + is regenerated by the respiratory chain.
Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.
