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.
It is true becouse international is between two or more countries.
The answer is: nature and nurture
Nature and nurture is the ongoing debate in psychological field on whether humans development is mostly influenced by environmental or genetic factors.
Twins often used in such experiment because they have same genetic material. This means that if they were separated, the researchers could analyze whether the environment where they grow up resulted in radical difference within the children's development.
Explanation:
For starting to compose a business message, it is important to collect all the necessary information by conducting a formal research or an informal research.
Now in order to avoid frustration and inaccurate messages while collecting the necessary information, the following questions we should ask ourselves are :
1. How should the sender structure the message?
2. What is the most interesting part of the message?
3. What will happen if the receiver does not take action?
4. When must the receiver take action?
5. What action does the receiver need to take?
