Answer:
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus. Chromatin structure plays a key role in regulating gene expression by allowing DNA accessibility to transcriptional machinery and transcription factors.

The answer is a) in biogeochemical cycles, nutrients are not synthesized anew but are recycled in the <span>biosphere.
Biogeochemical cycles are pathways by which chemical substances move through biosphere and geosphere (lithosphere), as well as atmosphere and hydrosphere. In these cycles nutrients are recycled, they are not lost. Let's take for example a carbon cycle:
</span>
<span>:- Carbon is released into the atmosphere as carbon dioxide from respiration.</span>
<span>- Producers (plants) absorb carbon dioxide and make carbohydrates in photosynthesis.</span>
<span>- Consumers (animals) eat producers and intake carbohydrates.</span>
<span>- After the death of both producers and consumers, decomposers (such as Actinobacteria, or other bacteria or fungi) eat that dead organisms and carbon are released into the environment.</span>
<span>
</span>
<span>So, carbon is not synthesized anew, but it is recycled.</span>
