If you were able to look very closely at a portion of dna and find methylated histones, you would be looking at a region of inactive chromatin.
- Histone methylation is the process by which methyl groups are added to the histone protein amino acids, which create the nucleosomes around which the DNA double helix coils to form chromosomes.
- Histone methylation is the addition of one, two, or three methyl groups to certain amino acids within a histone protein. Histones are coiled around DNA in the cell nucleus.
- These findings collectively imply that DNA methylation can be either active—as a probable contributor to levels of gene expression variation—or passive—as a result of or a separate indicator of gene expression levels.

- <em>See attached image for the diagram of being referred to</em>
Answer/Explanation:
In the diagram showing a typical food chain in an ecosystem, <em>the arrow that connects the sun to plants represents the flow of radiant energy</em>. The sunlight produces radiant energy, of which producers, such as plants, converts into chemical energy through photosynthesis.
The <em>next arrow linking the plants to the rodent shows the flow of chemical energy</em> in plants to primary consumers, such as rodents, who feed on them.
Also, rodents, when preyed upon by secondary consumers, such as wolfs and owls, pass on the same chemical energy to them. So <em>the arrows connecting the rodent to owl, and to the wolf both show the transfer of chemical energy</em> from the rodent to the owl and wolf.
The next arrow shows the <em>transfer of thermal energy from the wolf to the environment</em>, as the wolf release heat from the body resulting from daily functions it performs, and also, <em>thermal energy is released to the surroundings as heat during the decomposition </em>of the body of an animal.
The <em>arrow linking the wolf to the decomposer which break down the body and waste of the wolf represents transfer of chemical energy to the decompose</em>r, as they break chemical bonds to obtain the energy they need to survive and grow.
