1.
This regulates or controls the amount of light entering the condenser.
Correct Answer
B. DiapHragm
Explanation
The diaphragm is responsible for regulating or controlling the amount of light entering the condenser. By adjusting the diaphragm, the user can increase or decrease the intensity of the light, which in turn affects the brightness and clarity of the image viewed through the microscope. This feature is important for obtaining clear and well-illuminated images during microscopy.
2.
This supports the microscope
Correct Answer
D. Stage
Explanation
The stage is the platform on which the specimen is placed for observation under the microscope. It provides a stable and flat surface for holding the slide or specimen. The stage is an essential component of the microscope as it allows the user to position the specimen accurately and move it around for examination. Without a stage, it would be challenging to view and study the specimen effectively. Therefore, the stage supports the microscope's functionality and plays a crucial role in the observation process.
3.
_________ and _________ Are supported when carrying the microscope
Correct Answer
C. Arm and Base
Explanation
When carrying a microscope, the arm and base are the two parts that should be supported. The arm is the curved part of the microscope that connects the eyepiece and the objective lenses, while the base is the flat bottom part that provides stability. Supporting the microscope by the arm and base ensures that it is held securely and prevents any damage or mishandling.
4.
This remagnifies the image 10x, Because it contains a magnifying lens
Correct Answer
C. Eyepiece
Explanation
The eyepiece is the correct answer because it is the part of a microscope that contains a magnifying lens. This lens helps to remagnify the image that is produced by the objective lens. By using the eyepiece, the image can be further magnified by 10 times, allowing for a closer and more detailed view of the specimen being observed.
5.
This rotates and holds the objective
Correct Answer
A. Nosepiece
Explanation
The nosepiece is the correct answer because it is the part of a microscope that holds and rotates the objective lenses. The objective lenses are the ones responsible for magnifying the specimen being observed. By rotating the nosepiece, the user can switch between different objective lenses to achieve different levels of magnification. Therefore, the nosepiece plays a crucial role in adjusting the focus and obtaining clear images during microscopy.
6.
Thes are the primary lenses to magnify the specimen
Correct Answer
B. Objective
Explanation
The objective lens is the correct answer because it is one of the primary lenses used to magnify the specimen in a microscope. The objective lens is located near the specimen and provides the initial magnification of the image. It collects and focuses the light from the specimen onto the eyepiece, allowing the viewer to see a magnified image. The diaphragm controls the amount of light entering the microscope, the eyepiece further magnifies the image, and the low power lens provides a lower level of magnification compared to higher power lenses.
7.
This provides light for viewing the image
Correct Answer
C. Illumination
Explanation
The correct answer is "Illumination" because illumination refers to the light source that is used to view an image. In order to see the image clearly, a light source is necessary to illuminate the specimen on the stage. The illumination can come from various sources such as a built-in light in the microscope or an external light source. Without proper illumination, the image would be too dark or difficult to see, making it essential for viewing the image.
8.
This moves the stage up and down
Correct Answer
B. Course adjust
Explanation
The correct answer is "Course adjust" because it is the only option that suggests a movement of the stage. The other options, "Fine adjust," "Stage adjust," and "Condenser," do not directly indicate any movement of the stage. Therefore, "Course adjust" is the most suitable answer.
9.
This securely fastens the slide to the stage
Correct Answer
A. Stage clip
Explanation
The stage clip is the correct answer because it securely fastens the slide to the stage. This means that it holds the slide in place and prevents it from moving or sliding around during use. The stage clip is an essential component in microscopy, as it ensures that the slide remains stable and allows for accurate observations and measurements to be made.
10.
This makes small movements of the stage for focus adjustments
Correct Answer
B. FIne Adjust Knob
Explanation
The fine adjust knob is the correct answer because it is used to make small movements of the stage for focus adjustments. The coarse adjust knob is used for larger, initial adjustments. The condenser is used to focus the light onto the specimen, and the diaphragm controls the amount of light passing through the specimen. However, neither of these options directly relate to making small movements for focus adjustments.
