Answer: deoxyribose + phosphate group + cytosine

Explanation: DNA nucleotides are made up of three components: deoxyribose, phosphate group and a nitrogenous base. The nitrogenous bases found in DNA are Adenine, guanine, cytosine and thymine. The DNA is a double-stranded helical structure in which the phosphate group and deoxyribose make up the phosphodeoxyribose backbone that forms the rail of the helix while the nitrogenous bases that pair with one another form the rungs of the helix. In the base pairing, cytosine pairs with guanine and thymine pairs with adenine.

Ears

¿Qué es el oído y qué hace?

El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.

El oído externo

El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.

El oído medio

El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.
