Answer:

C). Edward Jenner

Explanation:

Vaccination is the approach that involves the activation of the adaptive immune response of humans. The provided vaccine contains the killed or weekend micro-organism which is given to the patient which activates the immune system of the patient.

The activated immune response provides protection against the related pathogen which was observed by the English practitioner Edward Jenner when he observed that the person infected with the cowpox was not infected with smallpox. He called this process as vaccination.

Thus, Edward Jenner is the correct answer.

• ¿Qué factores son clave para el manejo correcto del microscopio compuesto u óptico cuando se observa una muestra?
leonid [27]

Answer:

1-Tener en cuenta el tamaño del objeto a observar para utilizar la lente con el aumento correcto (es decir, 10 X, 40 X o 100 X)

2-Utilizar aceite de inmersión para ver objetos en 100 X

Explanation:

El microscopio óptico posee lentes (ocular y objetivo) los cuales permiten ampliar la imagen del objeto observado. El microscopio simple y el compuesto representan dos tipos de microscopios ópticos. El microscopio compuesto es aquel que utiliza más de una lente para aumentar la imagen observada, mientras que el microscopio simple usa una sola lente (la cual se denomina lupa). El microscopio óptico puede utilizar un aceite de inmersión que permite aumentar la resolución de la imagen a través de la inmersión de la lente objetivo. Es importante señalar que durante el enfocado de la muestra se debe tener sumo cuidado de no acercar demasiado la lente a la superficie del cubreobjeto, ya que esta puede dañarse.

During research with connected brain patients, researchers study __________, or left/right imbalances between cerebral hemispher
Goshia [24]

The correct answer is option A, that is, perceptual asymmetries.  

Visual perception refers to the procedure of organizing and interpreting visual information. It incorporates the tendency to determine and recognize the distinguishing characteristics of visual images like size, shape, position, orientation, color, and others.  

One of the most prominent features is the perceptual asymmetry or variability originating from the brain's perceptual responses to certain visual stimuli and/or to stimuli at the certain specific location of the retina. For example, vertical stimuli are represented and perceived better than oblique stimuli.  

Thus, during research with connected brain patients, the researchers study perceptual asymmetry or left/right imbalances between the cerebral hemispheres in auditory or visual processing speed.
