Answer:
The earth system usually refers to the different ways in which various physical, chemical as well as the biological processes interacts with one another and it includes the land areas, oceans, atmosphere, minerals and also the different cycles such as carbon, nitrogen, sulfur and so on.
These processes are continuously taking place at, on and below the surface of the earth, maintaining an equilibrium. The life existing on earth is directly dependent on these conditions and on-going processes. When there occurs changes in these conditions, then the lives on earth are affected.
For example, the lives are dependent on the climatic conditions, and when suppose the concentration of green house gases and other toxic elements are increased in an ecosystem, then the temperature will eventually rise, and there reaches a point when it becomes difficult for life to sustain. The organisms will suffer from different diseases.
Thus, the growth of life on earth affects when there occurs changes in the earth's system.
The body was preserved because the body was frozen in the cold temperature of the Alps shortly after he died and remained frozen until it was found.
<h3>How is a body preserved?</h3>

Answer:
To study the importance of the RNA telomer element, we can evaluate it by generating an in vitro state where all the purified components are included, organizing two groups, one of them will have an RNAase and the other will not, if it is observed that the telomeres extend to the component of the RNA, in the set where there is no RNAase, longer telomeres could be observed, if there were no influence of the RNA, the length in both groups would be the same
