Answer:
The chromatin structure undergoes various modification for proper gene expression. Histone acetylation, histone deacetylation, methylation and sumoylation are important for the epigenetics.
Epigenetics may be defined as the change in the genome that affect gene activity, its expression and heritable phenotypic change of the organisms. The DNA sequence is not altered in the epigenetic modification but the gene expression has been modified by methylation or acetylation.
Mitochondria is the organelle which is involved in cellular respiration and that is linked to development. The primary function is to perform cellular respiration.
Mitrochondria which is also known as powerhouse of the cell Because 32 ATP are created from this organelles. It is produced energy in the form of ATP when cell respire.Oxygen and glucose both are the reactants in the process of cellular respiration.
The major product of cellular respiration is ATP which is waste products include carbon dioxide and water.Cellular respiration takes place in mitochondria, which are often called the cell's "powerhouses" because they make maximume no of a cell's ATP. Glycolysis splits glucose into two three-carbon molecules and makes two molecules of ATP.

The correct answer to this question is for a fact true!
When and why this happens is because the members of that population get desperate (like limited supply of food, water, mates, or even habitats) so at that point of the situation all the creatures of that population are so desperate that they are willing to do everything and anything to survive. And then it becomes competition. That's one of the things that these 2 phrases are used for mainly:
"Every man is for himself"
"Survival for the fittest"
