In this case, the management of natural resources positively affects the human population, which might be to detriment of biodiversity.
<h3>What are natural resources?</h3>
Natural resources are any type of resources that can be obtained from nature (e.g., wood from trees).
Natural resources can not be indefinitely extracted from nature because it supposes a loss of biodiversity.
In conclusion, in this case, the management of natural resources positively affects the human population, which might be to detriment of biodiversity.

Answer:
2n=46(duplicated)
Explanation:
Prior to cell division, which can either be meiotic or mitotic, the DNA content of the cell gets doubled in the Synthesis phase of the Interphase stage. In humans like myself, our cells consist of 23 pairs of chromosomes or 46 chromosomes. The DNA doubles in order for each daughter cell to get the correct number of genetic material.
After the S-phase, the chromosome number in the human cell does not change, just that each individual chromosome gets replicated or duplicated to form sister chromatids. Therefore, the human cell will contain 46 duplicated chromosomes or 92 sister chromatids after Synthesis phase and before the meiotic division.
Note that, humans are diploid organisms (2n) i.e. two set of chromosomes. Hence, they undergo meiosis to reduce their ploidy level from diploid (2n=46) to haploid (n=23).

<h2>Epigenetic modification </h2>
Explanation:
A methyl group bound to DNA inhibits transcription of a gene describes an epigenetic modification
Epigenetic modifications include: histone modifications and methylation
Methylation is the main cause of gene silencing for example methylation at lysine residue of histone protein, H4 leads to gene repression
Small silencing RNA molecules are of two types: micro RNA (miRNA) and small interfering RNA (siRNA)
miRNA directs degradation of target mRNA when makes perfect complementary while suppress mRNA translation when makes partial or imperfect complementary
siRNA primarily mediates degradation of target RNA
