DNA and RNA both are type of nucleic acids and are polymeric forms of nucleotides. Nucleotide is a complex molecule made up of a pentose sugar, a nitrogenous base, and a phosphate group.
DNA and RNA differ from each other in these nucleosides. A pentose ribose sugar in a nucleotides forms a<span> ribo-nucleotide, </span><span>a monomer of RNA, while deoxy-ribose sugar forms </span><span>deoxy-ribonucleotide, </span>a monomer of DNA.
I hope this helps.
Answer: brief fast acting; slow acting
The nervous system is to brief fast acting as the endocrine system is to slow acting

Different kinds of fossil fuels — coals, oils, and natural gases — formed as dead plants and animals decayed. Scientists refer to such remains as “organic matter.” The element carbon is the foundation for organic matter on Earth
