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.
Maya is using "visualization".
Visualization is an extraordinary instrument for overseeing anxiety. Visualization is simply the demonstration of envisioning in a quiet and safe condition - a place that makes you casual and glad. By exchanging yourself there rationally, you're ready to quiet your brain and body and adequately occupy yourself with something that unwinds you.

complete question;
distinguish between culture and society then identify three factors that influence cultural change.
Answer:
The most common definition of culture is that it is a way of life. It is a way of life of a particular group of persons that is passed down from one generation to another generation.
we can also define the word society as group of persons that live together in an ordered community. The people in a society could share same beliefs as well as have common interests. A society is also a combination of different persons that are of different cultures.
The main difference between society and culture is that while the society comprises just of the people who share same beliefs and practices, culture is the beliefs and the practices of this people.
several factors are responsible for cultural changes in a society. three of these influences are:
- <u>contact: </u> When two societies come in contact with each other, there is likely to be a change in culture of both societies. This is known as cultural diffusion (the spread of cultural belief from one society to another society).
- Evolutionary changes in technology: Any form of advancements or evolutions in technology could bring about changes in culture. Technological evolution in production technology or changes in means of transportation and communication could influence cultural changes.
- Geological and ecological influences: These are factors that influences cultural changes. An example is rainfall, altitude, proximity to sea.
These factors are all capable of deciding the culture as well as the lifestyle of dwellers.
