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

Explanation:
1. Epigenetic modification:Those changes which do not involve the alterations in the sequence of DNA, means there in no change in DNA sequence, like addition, deletion or such other type of changes in the sequence of nucleotide do not occur
2. Epigenetic describes any such type of modification of chromosome( which do not change the sequence of nucleotide), especially histone modifications, and these changes may be heritable or not or associated with a phenotype.
B. They belong to the same species and C. They live in the same area.
Explanation:
This is an educated guess. If you think about it, if there was a population of humansss, we dont have the same parents nor the exact genes so to only two that make sense is those to （＾ω＾）
About 20% of the pesticide will be absorbed by the mouse. This is because the direct effects of the pesticide were already absorbed by the grasshopper and processed within its body system, also probably leading to excretion in different sorts. Therefore the effects of the pesticide is lesser compared to the mice.
