Answer:
nucleus
Explanation:
Chromosomes are contained inside the cell's nucleus . These are long, thin, threadlike structures made from molecules of DNA that store genetic information. Chromosomes are found in the nucleus of body cells in pairs - one chromosome is inherited from the mother and one is inherited from the father.
Atoms are the smallest unit of matter. Atoms of isotopes of the same element contain the same number of protons.
<h3>What are isotopes?</h3>
Isotopes are atoms of the same element which have different numbers of neutrons but the number of protons and electrons remains same.
As the isotopes of the atom have the same number of protons, so, their atomic number will also be the same.
Thus, it can be concluded that atoms of isotopes of the same element contain the same number of protons.

Just about every living organism on Earth can be placed in one of two classes: prokaryotes and eukaryotes. A prokaryote is a cell without a nucleus and eukaryotes are cells that contain nuclei. There's one quick test to distinguish prokaryotes from eukaryotes: if you can see a single organism, it's a eukaryote.
Hi!
Two chromosomes that make up a homologous pair can differ. The reason why they would differ is because they contain different alleles for the same trait.
When these chromosomes are homologous, this just means that they have the same genes in the exact order. But, the actual sequences at some of the geni loci are a little different. They are different because they are alleles.
Hope I could help!
