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.
The answer is B, public opinion polls
The new number, 200, is 400 less than the original number. What is the approximate percent change?
Answer:
The looking-glass self.
Explanation:
<u>The looking-glass self</u> is a sociological theory created by American sociologist Charles Cooley. This theory refers to a process where individuals base their self-image or self-worth on how they believe they are perceived by others. Cooley mentions there are three steps in this process: how we believe we appear to other people; how we believe they judge us, and how we act or change depending on how we judge others. In this example, Martin has formed an idea of how he thinks others see him and judge him - ridiculous and as a slob because of the stain on his shirt. This leads to him feeling embarrassed.
