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.

The balance that can be used to measure a mass reading of 6.521 g will be a balance with ±0.001 g tolerance.
<h3>What is the tolerance of a balance?</h3>
The tolerance of a balance is the number of decimal place values displayed on the balance and it is the acceptable measurement limitations (in grams) that a balance can tolerate.
- As such, depending on the decimal place value behind a mass reading will determine the balance used for measurement.
Since no mass reading was given, let's make two assumptions about mass reading.
Mass reading Assumptions
1 6.521 g
2 4.23 g
- The balance used for the 6.521 g mass reading is a balance with ±0.001 g tolerance.
- The balance used for the 4.23 g mass reading is a balance with ±0.01 g tolerance.

Among the Koyukon people of the arctic, sacred time tends to focus on the distant time.
<h3>
Who are the Koyukon people?</h3>
- The Koyukon are an indigenous Athabascan people of Alaska who speak the Athabascan language family.
- They have lived in their ancestral homeland along the Koyukuk and Yukon rivers for millennia through hunting and trapping. Today, many Koyukon continue to live in a similar way.
- The Koyukon language is a member of the vast Na-Dené or Athabascan language family, which is traditionally spoken by many indigenous populations in northwest North America.
- Other Na-Dené languages, such the Navajo and Apachean variants, are also spoken in Mexico and the American Southwest as a result of long-ago migrations of related peoples.
