Answer:The correct answer is A) Coarse adjustment knob.
Explanation:The coarse adjustment knob is used to raise and lower the stage in a microscope. It is a large knob that moves the stage up and down in larger increments. By turning this knob clockwise, the stage moves upward, and by turning it counterclockwise, the stage moves downward.
The other options, such as the nosepiece, fine adjustment knob, and mechanical stage knobs, have different functions in a microscope. The nosepiece is responsible for holding and rotating the objective lenses, which are used to magnify the specimen. It allows you to switch between different magnifications by rotating it. The fine adjustment knob is used to make smaller, precise adjustments to the focus of the microscope. It moves the stage up and down in smaller increments to achieve a clearer image.
The mechanical stage knobs are used to move the stage horizontally or vertically to center the specimen under the objective lens. These knobs are helpful for scanning the entire specimen and locating specific areas of interest.
In summary, while all the options mentioned have specific functions in a microscope, the coarse adjustment knob is specifically used to raise and lower the stage.
Answer:
A single nucleotide polymorphism (SNP) is the most common gene variation found among people. A SNP represents a change in a single DNA block, called a nuecleotide, being able, for example, to replace a nucleotide cytosine (C), with a nucleotide thymine (T), guanine (G) or adenine (A) in the genome. They represent the 90% of all the human gene variations.
