Answer:

A

Explanation:

Deoxyribosenucleic acid (DNA) is one of the two types of nucleic acids, the other being RNA. DNA is a polymer called polynucleotide made up of subunits called NUCLEOTIDE. Each nucleotide is made up of components that make up its structure. These components are:

1. A five-carbon sugar, which can be Deoxyribose or ribose depending on whether it is present in DNA or RNA respectively. The difference in the two sugars is the deficiency of one oxygen atom in deoxyribose.

2. Phosphate group with the structure PO3 (4-)

3. Nitrogenous bases, which are four in number viz: Adenine, Guanine, Cytosine and Thymine/Uracil. Thymine is only present in DNA while Uracil is only present in RNA.

Hence, the answer to the question is Deoxyribose, phosphate and Thymine (nitrogenous base).

mojhsa [17]

Answer:

5.37 °C

Explanation:

The optimal condition for most enzymes in the small intestine is 37 °C.

Enzymes are responsible for mediating several biological processes in the human body. The optimal condition for enzymes in the small intestine has an optimum pH of about 7.5 and the temperature is 37 °C, which is the normal body temperature of the human body.

Hence, the correct option is "5. 37 °C".

La sangre sale del ventrículo derecho por las arterias pulmonares y se dirige a los pulmones.
AveGali [126]

Answer:

Si, esto es lo que se conoce como circulacion menor.

Explanation:

La sangre cumple un recorrido en el corazon a la cual se la llama circulacion mayor, una vez que se continua su camino hacia los pulmones ahi ya pasa a ser circulacion sanguinea menor.

Estas circulaciones estan sumamente coordinadas y tienen un orden ritmico, con un unico fin, que es oxigenar la sangre que se recolecta de todo el organismo.

Es asi como la sangre que viene con CO2 entra a los pulmones posterior a la eyeccion cardiaca y cumple con el proceso de homeostasis en el alveolo y se oxigena.
