Answer:
The civil year allows us to have an idea of how long our planet has existed.
Explanation:
Calendar year is the 12-month period that corresponds to 365 days of the year, counting from 1 January to 31 December. Geological time, in turn, refers to the didactic organization of the evolution of planet Earth and the forms of life that inhabit or inhabited it. It is an instrument used by Earth's geologists and scientists to analyze and chronologically categorize (through the concept of a civil year) the natural evolution of the world in which we live, in order to better understand its past.
The civil year allows geological time to expose the number of years and days that planet Earth (and its forms of life) are in existence.

I think the correct answer from the choices listed above is option D. A prokaryote that release energy if it is in an environment without oxygen and dies when exposed to oxygen, and uses fermentation would most likely be an obligate anaerobe. Obligate anaerobes<span> are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.</span>
