Answer:

C) parfocal.

Explanation:

A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.

A microscope is said to be parfocal if its lense is binocular and they can both be in focus.

Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.

Una parte de la radiación
diamong [38]

La troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

En la capa de la troposfera, que es la capa más baja de la atmósfera, hay vapor de agua, dióxido de carbono, metano y algunos otros gases que son responsables de la absorción de la radiación infrarroja. Parte de la radiación infrarroja se escapa al espacio, pero una parte es detenida y absorbida por los gases de efecto invernadero presentes en la atmósfera.

Esta absorción de radiación infrarroja por los gases de efecto invernadero contribuye a un aumento de la temperatura de la superficie de la tierra y de la atmósfera. Entonces, podemos concluir que la troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.
