En microscopía óptica, la inmersión (generalmente en aceite, aunque también se puede efectuar en agua o con medios sólidos) es una técnica utilizada para aumentar el poder de resolución de un microscopio. Esto se consigue mediante la immersión en un aceite transparente de alto índice refractivo tanto de la lente del objetivo como del espécimen a observar, aumentando así la apertura numérica de la lente del objetivo.

Los aceites de inmersión son sustancias transparentes con las propiedades ópticas y las características de viscosidad necesarias para su uso en microscopía. Los aceites típicos utilizados suelen tener un índice de refracción de alrededor de 1,515.1​ Un objetivo de inmersión es una lente especialmente diseñada para ser utilizada de este modo. Muchas lentes condensadoras también proporcionan una resolución óptima cuándo están inmersas en aceite.

El primero en desarrollar está técnica a mediados del siglo XIX fue el óptico italiano Giovanni Battista Amici (1786-1863).

g100num [7]

Answer:

The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.  

This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.

True [87]

Answer:

precession

Explanation:

The orbit isn’t the simple ellipse, rather it is one that moves a little, loop after loop. This motion is called precession, and you may have heard about it when astronomers talk about the precession of the orbit of Mercury
