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:
Answer: A parachute landing fall (PLF) is a safety technique that allows a parachutist to land safely and without injury. ... When executed properly, this technique is capable of allowing a parachutist to survive uninjured during landing speeds that would otherwise cause severe injury or even death.
Explanation:
cant make the diagram but
Examples are used to "exemplify" a situation. Hence, we take an abstract theory and we make it more approachable by showcasing some details. Hence, we have that the example makes abstract idea more concrete. The first 2 choices are wrong since they state the opposite. The 3rd choice is rather irrelevant, examples can make it more or less didactic. Hence, the 4th choice is correct.
First question would be D because it’s where the land ends !
Answer: A) a combination of results from many related studies.
Explanation:
Meta-analysis is defined as the study technique that is used to approach previous related research result in systematic manner to extract result about research content.It does not rely on conducting new research rather clinical test is conducted. This analysis is controlled and quantitative.
Other options are incorrect because correlation study, experimental research and interference approach option is not the field where metal analysis is used.Thus, the correct option is option(A).
