Answer:
Histone acetylation or DNA methylation.
Explanation:
The epigenetics may be defined as the genetic phenomena that might cause mutation in the organism's genome. The DNA sequence of the organisms do not get changed in epigenetics.
This phenomena is limited whether the gene is herited from the mother ot the father. The phenomena like acetylation of histones increase the gene expression. The DNA methylation and histone deacetylation at specific residues reduces the gene expression.
Thus, the answer is histone acetylation or DNA methylation.
The correct answer is D. Digestion.
Digestion is termed as the breakdown of food which has large insoluble molecules to small soluble molecules which makes them to be absorbed in the blood plasma.
Based on the way which food is being broken, it will depend on the form of catabolism which is used in the digestion. For example, catabolism is divided into chemical and mechanical digestion where mechanical digestion breaks down large to small pieces of food.
Those pieces of food are accessed by digestive system. In chemical digestion it is the enzymes which broke down molecules of food.
Venus is the answer, you can tell easily because Venus has no moons or rings :)
In the thylakoids of the grana, light reactions take place and in the stroma , dark reaction takes place. So all in all, in both places together photosynthesis is carried out
