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)
Rats can learn to run complex mazes even without food rewards present.
Explanation:
Biological predisposition to learning is brought about by an internal inherited quality that increases the likelihood of having a condition or exhibiting a certain pattern of behavior.
It occurs in humans and animals and has to do with genes passed down from parents to children.
In this case, the genetical makeup of the rats can cause them to learn to behave in a certain way over time.

Hello. You forgot to say that this question is about the film “Sex Verification Testing of Athletes”.
Answer:
The film shows that in most sports male athletes (who have a higher testosterone rate) outperform female athletes by about 10% in most sports. Testosterone is a hormone that is directly linked to athletic performance and this is the evidence that the film shows to affirm that "a high level of testosterone offers an unfair advantage in women's athletics"
This is adequate evidence, since it starts from a biological and scientifically proven principle, saving some exceptions.
