Acid rain is simply rainfall that has been rendered acidic due to water vapor reacting with nitrogen oxide ad sulphur dioxide very high up in the atmosphere.
Acid rain is not only a threat to the ecosystem and environment, but also seriously damages buildings and sculptures.
Marble and limestone are especially vulnerable to acid rain. This is because the two building or construction materials contain calcite which is easily dissolved by acid.
Concrete surfaces and paint finishes are also seriously damaged by acid rain.

Answer:
Considering the organization of the body the level of organization in which proteins like collagen are found is the molecular level, and this level of organization allows the construction of the structure and functions of the whole body.
Explanation:
Collagen is a protein molecule that belongs to the molecular organization level, like all biomolecules.
Proteins have multiple functions in the body:
- <em>They participate in the construction or structure of the body.
</em>
- <em>They form specialized proteins, the enzymes, to facilitate organic chemical reactions.
</em>
- <em>They are part of the structure of cell membranes, allowing cellular recognition and transmembrane transport.
</em>
In this way <u>the protein molecules, belonging to the molecular level, contribute to the organization of the whole body</u>.
