When viewing a specimen under the microscope you should always start with the?
low power objective lens to locate and focus on the specimen before moving to higher magnifications.
When focusing with a microscope do you always focus toward the specimen?
No, when using a microscope, you should focus away from the specimen initially by moving the objective lens upward, then slowly bring it down towards the specimen to avoid damaging the lens or the specimen.
When observing a slide should the specimen be on the top or bottom surface of the microscope?
The specimen should be placed on the top surface of the microscope slide. This allows the light to pass through the specimen from below and be magnified by the lenses in the microscope to form an image for observation.
How should the condenser be set when viewing bacteria?
When viewing bacteria under a microscope, the condenser should be set to the highest position to maximize the amount of light passing through the specimen. Adjust the condenser's aperture diaphragm to enhance contrast and resolution, but be cautious not to overdo it as it may lead to blurriness. Fine-tune the condenser until the bacteria appear as well-defined, evenly illuminated cells.
Which part of the microscope will you adjust if the onion cell you are observing under the HPO is not clear?
You should adjust the fine focus knob to sharpen the image when viewing the onion cell under high-power objective (HPO) on a microscope. Rotate the knob gently to focus the specimen until the image appears clear.

When beginning to focus a microscope what lens should you use?
You should start by using the lowest power objective lens, usually the 4x or 10x objective, to locate and center the specimen on the slide. Once the specimen is in focus, you can switch to higher magnifications for more detailed viewing.
What power must be in first place a slide on a microscope stage?
The lowest power objective lens should be in place when placing a slide on a microscope stage. This allows for easier focusing and initial viewing of the specimen at a lower magnification before switching to higher magnifications.

List three differences between a monocular and a stereo microscope?
Monocular microscope has one eyepiece, while a stereo microscope has two eyepieces for viewing. Mono microscope typically offers lower magnification compared to stereo microscope, which provides better depth perception of the specimen. Stereo microscopes are suitable for viewing three-dimensional objects or larger specimens due to their wider field of view and depth of focus, while monocular microscopes are often used for viewing two-dimensional specimens at higher magnification.
What way should the mirror of a microscope face?
The mirror of a microscope should face the light source, such as a lamp or natural light. This is to ensure that the light is reflected up through the microscope stage and specimen, making the specimen easier to view under the lenses.
What does this movement do in microscope?
It allows you to focus the specimen by adjusting the distance between the lenses and the specimen.
Which part of the microscope will you adjust if the onion cell you are observing under the HPO is not clear?
You should adjust the fine focus knob to sharpen the image when viewing the onion cell under high-power objective (HPO) on a microscope. Rotate the knob gently to focus the specimen until the image appears clear.
What you want to look at under a microscope is put one of these?
A slide.
What power must be in place when you first find an image in the microscope?
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.
