Epigenetics is the study of how DNA methylation and alterations to chromosomal proteins affect a gene or group of genes express themselves. For changes in a gene's expression, both of these are need.
In a biological process called DNA methylation, methyl groups are added to the DNA molecule. A DNA segment's activity can be altered by methylation without the sequence changing. DNA methylation usually inhibits transcription of genes when it occurs in a gene promoter.
Epigenetics literally translates to "along with changes in genetic sequence." Any procedure that modifies gene activity without altering DNA sequence and results in modifications that can be passed on to daughter cells is now included in the term. Is called Epigenetics.

The answer is C because the drought turned the land brown which made the grasshoppers turn brown for camo.
The correct answer is - B. Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells.
The processes of mitosis and meiosis are often confused with one another, mostly because of the similarity in their names.
The mitosis is a type of cell division where the end result is two daughter cells, each of the cells has the same number and kind of chromosomes as the parent nucleus. Thus is typical for the growth of tissue.
The meiosis is a type of cell division where the end result is four daughter cells, each of the cells having half the number of chromosomes of the parent nucleus. This is typical for the gametes and the plant spores.
