During chemical reactions, the chemical bonds between atoms are altered. ... Enzymes make chemical reactions take less time by decreasing the activation energy of the chemical reaction. The role of the enzyme-substrate complex is to provide the energy to break or form bonds in chemical bonds.
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.
