<span>Nucleic acids. Like proteins, nucleic acids are very large molecules. The nucleic acids are composed of smaller units called nucleotides. Each nucleotide contains a carbohydrate molecule (sugar), a phosphate group, and a nitrogen-containing molecule that, because of its properties, is a nitrogenous base.</span>Organic Compounds - Cliffs Notes<span>https://www.cliffsnotes.com/study-guides/biology/biology/the.../organic-compounds</span>
This is true! Minerals were mined both on the surface as well as in mines and caverns underground.
When a substance becomes part of a mixture, its chemical properties ONLY change if the resulting mixture is homogeneous. Otherwise nothing happens to the properties.
Explanation:
The formula of a selected pure substance doesn't amendment simply because it becomes a part of a mix. Chemical properties can amendment in a very mixture. If you've got a mix of water and alcohol, the melting point are below 0C. That doesn't mean that water now not freezes at 0C, it simply means that the mixture of water and alcohol doesn't freeze at 0C.
