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

In order for the american way of life to be safe Roosevelt said that Germany,Japan and Italy must be defeated.
It grew from Western Europe to Eastern Europe, then collapsed to Eastern Europe
Answer:
<em>(e) top-down processing</em>
Explanation:
Since the brain is basically focused on the sensory systems higher.
Higher-level stages of cognition such as reasoning, are therefore known to be at the top of the process of feeling and perception.
But at the other hand, low-level brain structures, like those participating in sight, touch, or hearing sensory systems, are known to be at the bottom.
Top-down processing refers to how our brains use information that one or more of the sensory systems have already put into the brain.
It is a cognitive process that begins with our emotions, flowing down to functions at lower levels, such as the senses.
