Answer:
La respuesta correcta es "a. arterias, b. venas; y c. capilares".
Explanation:
Los vasos sanguíneos son una serie de conductos a través de los cuales el cuerpo transporta la sangre, asegurando que todas las células del cuerpo tenga acceso a oxígeno, elemento necesario para la respiración celular. Hay tres tipos de vasos sanguíneos: arterias, venas y capilares. Las arterias llevan la sangre del corazón a los órganos, las venas transportan la sangre de los órganos al corazón y los capilares son vasos muy pequeñitos que llegan a las partes más pequeñas del cuerpo.
Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.

In commensalism, one organism benefits from the relationship while the other species involved neither benefits nor is harmed. The benefits for one organism can be in a variety of forms, including food, shelter, transportation and seed dispersal.
