Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.

Individuals inherit one 'factor' from each parent for each trait. A trait may not show up in an individual but can still be passed onto the next generation.
Explanation:
Los geólogos localizan el epicentro de un terremoto tomando mediciones de tres sismógrafos. Estos se miden en las estaciones sísmicas y dan la distancia que las olas del terremoto viajaron para llegar a la estación.
