Answer:

E. Nucleus

Explanation:

All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.

The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:

EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.

Anon25 [30]

The option that best illustrates the similarity and difference in the elemental makeup of these molecules is that carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements. That is option B.

Carbohydrates are macromolecule found is food substances that plays a vital role of energy supply to the body.

It is made up of chemical elements such as carbon,hydrogen and oxygen in the ratio of 1:2:1.

Lipid is another macromolecule found in food which is an energy reserve for the body.

Lipids are made up of elements seen in carbohydrates such as carbon, hydrogen and oxygen but contain many more hydrogen atoms than oxygen atoms.

Proteins are another type of macromolecule found in food which helps in body building and repair of worn out tissues.

Proteins are made up of elements seen in carbohydrates and lipids with the addition of nitrogen atom.

Therefore, carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements.
