Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
Answer:
Water moves in and out of cells by osmosis through the cell membrane. ... Aquaporins selectively conduct water molecules in and out of cells, while preventing the passage of ions and other solutes.

Answer:
DNA ⇄ RNA → PROTEINS.
Explanation:
Central dogma explains the flow of genetic information of the living organism. The DNA is converted to RNA by transcription and further into protein product by the process of translation. DNA can increase its number by replication process.
Retroviruses do not follow the central dogma and they have the ability to convert the RNA into the DNA molecule by the enzyme reverse transcriptase. Their central dogma is as follows:
DNA ⇄ RNA → PROTEINS.
Thus, the answer is DNA ⇄ RNA → PROTEINS.
