The <em>answer </em>is option A i.e "32%". According to Chargraff's rule, Number of purine (adenine+guanine) = Number of pyrimidine (cytosine+thymine). Hence, the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

Explain how the biogeochemical cycles are essential for life.
Over [174]
<h3><u>Answer and explanation;</u></h3>
  • <em><u>Biogeochemical cycles are cycles or pathways through which a chemical element or a molecule circulates through the abiotic (non-living) ad biotic (living) components of an ecosystem.</u></em>
  • <u><em>All chemical elements occurring in organisms are part of biogeochemical cycles.</em></u> Carbon, hydrogen, oxygen and nitrogen are the key components in life of organisms. Therefore, the carbon, nitrogen, and oxygen cycles are the most important biogeochemical cycles.
  • <em><u>Biogeochemical cycles are essential for life and important to the ecosystems because matter on earth is limited in amount, and space for dead organisms as well. </u></em>
  • <em><u>Additionally, biogeochemical cycles are important as as they transport and store these chemical elements so that they can be used by living organisms. </u></em>
