Which statement describes one way that rna differs from dna?
a.) one is a protein, and the other is a nucleic acid.
b.) they contain different five-carbon sugars and a different nitrogenous base.
c.) they are both carbohydrates, but one is a polysaccharide.
d.) one provides energy, and the other carries genetic information.

the answer is B choice 2

Option-B

Explanation:

Both DNA and RNA are the nucleic acid which is composed of nucleotide monomers.  The nucleotide monomers are composed of a phosphate group, a 5-carbon sugar and different nitrogenous bases.

The DNA and RNA differ from each other as:

1. Sugar- The sugar in RNA is ribose whereas, in DNA, the sugar is called the deoxyribose as oxygen is released from the 2'OH group in the structure.

2. Nitrogenous bases- In DNA there are 4 different bases called- adenine, thymine, guanine and cytosine whereas RNA has the same bases except for thymine as it contains uracil instead of thymine.

Thus, Option-B is correct.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
