why is rna a polymer and a macromolecule

Answer:

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.

Question
Use the text to identify the sentences with evidence that matches the claim.

Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.

1) Biodiversity refers to the total number of different species of all kinds living in an area.

2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.

3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.

4) Surprisingly, rain forest soil is very poor.

5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.

6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.

ASAP Determine whether the statement is true or false and why. “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming more human-like the closer to the present they are, showing a clear evolution into humans.”
A. False, it should read “We have discovered no series of humanoid fossils that are similar to humans, showing a clear lack of any transitional fossils as evidence of human evolution”
B. True
C. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to a different period in time becoming less human-like the closer to the present they are, showing a clear evolution away from humans.”
D. False, it should read “We have discovered a series of humanoid fossils that are similar to humans, but not human. Each of these humanoid species dates to the same period in time, showing that many human-like species existed at once, but all went extinct.”
