Answer:
B
Explanation:
Ribosenucleic acid (RNA) and Deoxyribosenucleic acid (DNA) are the two nucleic acids formed from building blocks called nucleotides. Although, they are formed from the same building blocks, but have structural differences.
One of the differences between RNA and DNA is that unlike DNA that is a double-stranded molecule formed by the complementary base pairing of two nitogenous bases (nucleotides), RNA is a single-stranded molecule made up of shorter nucleotides.
Answer:
Universal Solvent
Explanation:
Water is known as a universal solvent as it is capable to dissolve more substances than any other liquid.
This is how molecules of water are attracted to other types of molecules.
A true universal solvent doesn't exist but water is the closest to it, as its polar property allows water to dissolve substances.
