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.

According to Edward, these rules usually would be introduced by each members of the social group right before they become the member of that social group. Examples of such rules are the employee orientation that companies do for new recruits.</span>
Peristalsis is involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body. It occurs in the stomach, esophagus, and intestines.
That statement is true
If your focus is solely for taking notes, you should learn to let go potential disagreement between you and the speaker and focus what the speaker had to say. You should also think critically and formulate questions if there is something that you do not understand.
