Answer:
Abiotic
Explanation: Water is not a living thing, therefore water is an abiotic factor.
It is d, a substance that participates in a chemical reaction. You can also tell it just by looking at the stem of the term :)
Answer: This is largely because RNA is single-stranded. The correct option is D.
Explanation:
RNA ( Ribonucleic acid) is a single stranded nucleic acid which is composed of:
--> A nitrogenous base: RNA consists of four nitrogenous bases which includes adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA (Deoxyribonucleic acid).
--> A five-carbon sugar: it contains ribose as its pentose sugar and
--> A phosphate group.
The main function of RNA is to convert the information stored in DNA into proteins.
RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure. This is because it is single-stranded. This is due to the presence of a hydroxyl group at the 2' position of the ribose sugar. The presence of this functional group causes the helix to adopt the A-form geometry rather than the B-form most commonly observed in DNA.
