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:
C. Groupthink
Explanation:
Most of us can remember at least once when a group, when making a decision for the sake of beloved harmony, set aside individual ideas and opinions and followed a not very rational path. This kind of dysfunction in decision making, which in English is called groupthink. Groupthink occurs when an environment begins to show overestimation of group power and morality, with thoughts such as "Yes, we are good in every way!"; lack of openness to new ideas, always ignoring or rationalizing any questioning about the falseness of group assumptions and pressure for uniformity. These "symptoms" are similar to what is happening in the group exposed in the question, so we can conclude that the question is describing a situation where groupthink occurs.
Answer:
100 or higher
Explanation:
The Wechsler Intelligence Scale for Children- Revised is a scale that tries to measure intelligence based on ten abilities. In addition, the IQ scores have a mean of 100 and deviation of 15. That being said, if we are considering the 50th percentile or above, then the kids selected for this test would have to have an IQ score of 100, being that 100 is the mean for the WISC-R.
Answer:
Road building and purchasing military equipment are examples of purchasing by government.
Explanation:
The government is responsible for the purchasing of military equipment and road building.
This purchases fall under the category of gross investment expenditures.
Investment meaning that the government treats this as its own assets.
