Answer:

D. It is the most massive part of the atom.

Explanation:

As you know, an atom is formed by the electrosphere (where the electrons are) and the nucleus (where the neutrons and protons are).

The nucleus is a very small region in the atom and although it occupies less space than the electrosphere, it contains practically the entire atomic mass, for this reason it is the densest region of the atom. This is because the entire mass of an atom corresponds to the sum of all its protons and the protons are in the nucleus.

diamong [38]

<h3>Genomic imprinting represents yet another example of non-Mendelian inheritance. Just as in conventional inheritance, genes for a given trait are passed down to progeny from both parents. However, these genes are epigenetically marked before transmission, altering their levels of expression.</h3>
