Answer:
The oblique illumination is
used by the microscopists to resolve N. Spencrii in the Dark Field Condensers.
Explanation:
It was found that the use of oblique light was required to resolve the striae. Oblique illumination was the first step toward dark field microscopy. In dark field, light
seems to radiate from the specimen while all the rest of the field is black. Resolution is as good as that in bright field while contrast is enhanced.
In dark field microscopy, no
direct light from the condenser enters the objective lens. Only light
that is reflected, refracted or diffracted by the specimen enters the objective. The dark field condenser produces a circle of light. The
light is at an extremely oblique angle to the surface of the slide. This
oblique light comes to a focus on the specimen. It then diverges so
strongly that no direct light enters the objective. This type
of illumination is a hollow cone of light.
Answer:
C. systematic desensitization
Explanation:
systematic desensitization is a form of behavioral treatment that is carried out by exposing the patients to the source of fear in a controlled manner. The intensity of the exposure usually will start really small and will be increased as the treatment goes on. Over time, the patient will be used to confronting the source of fear and the fear will eventually reduced / went away.
This can be seen in what the Therapist did to Kayla. He asked her to think about her fears and tried to relax in that situation before eventually move up to asking her to use crowded elevators to conform her fear of closed spaces.
I think this is called culture shock. This gesture of touching the head of the Ywadees is something new to the other cultures. People outside their culture believes that this is wrong but for the Ywadees, this is their belief and way of life. For a sociologist, they believe that there is no right or wrong in culture. People should respect other cultures.
