Why is rna a polymer and a macromolecule

RNA is a polymer because it is made up of many monomers called nucleotides. Moreover, RNAs can form macromolecules because many RNAs are large molecules (i.e., polynucleotide chains).

Explanation:

Ribonucleic acid (RNA) can be defined as a single-stranded nucleic acid polymer of the four nucleotides. In RNA, each nucleotide is composed of a 1-ribose sugar, a 2-phosphate group and 3-one of four types of nitrogenous bases: Adenine (A), Cytosine (C), Guanine (G), and Uracil (U), which are covalently bonded to form polynucleotide chains. There are different types of RNAs such as mRNA, tRNA, rRNA, miRNA, circ-RNAs, lncRNAs, etc. Many of these RNAs form large single-stranded (ss) molecules, i.e., polynucleotide chains. For example, an mRNA sequence may have a length of 5,000 nucleotides (5 kb) or even more, and there are RNA viruses that have more than 20000 nucleotides (20 kb) in length.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
