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:

Both B and C
Explanation:
Sidewalk ramps and Braille are forms of accessibility for people with disabilities. If a person has to use a wheelchair and access a building, a ramp is the only way to do so. Braille is used on signs for disabled people in order to read needed information. Both are forms of accessibility for people with disabilities who would not be able to function correctly without them.
The American with Disabilities Act of 1990 prohibits any kind of discrimination based of disability. The Act requires employers to provide reasonable accommodations to people with disabilities and imposes disability requirements on public accommodations.
Answer:
Explanation:
<u>Social service organizations are the ones that are most likely to detect the problem in society and analyze how it should be approached.</u> They will see what are the priorities of the community, what can be approved, and what are the actions that need to take place in order for a certain problem to be solved.
<u>Organizations know the governmental, civil, and law procedures that need to take place to make the change.</u> <u>They usually already have some support of governmental bodies, employees, and volunteers who can work on the issue. </u>
Therefore, social service organizations are more likely to get into the process of solution and guide the social transformation through it.
