What observe lens should be used when you first look at a specimen under the microscope?
When first examining a specimen under a microscope, you should start with the lowest power objective lens, typically the 4x or 10x lens. This allows for a broader field of view, making it easier to locate the specimen. Once the specimen is in focus, you can then switch to higher power lenses for more detailed observation. Always ensure to adjust the stage and focus carefully to avoid damaging the slides or lenses.

When did Robert hooke create this first microscope?
Robert Hooke created his first compound microscope in the 1660s. This microscope allowed him to observe microbes and other tiny organisms for the first time, which contributed greatly to the field of microbiology.
What is used for first focusing on the microscope?
The coarse adjustment knob is used for first focusing the microscope. This knob moves the stage up and down quickly to bring the specimen into rough focus.
What on a microscope is used for first focusing?
The coarse adjustment knob is used for first focusing when using a microscope. It is used to move the objective lens closer to or farther away from the specimen to bring it into rough focus.
What steps should you take if you are trying to focus on a specimen and the image remains blurry?
First, make sure that the specimen and the lens are clean. Check the focus adjustment on the microscope to ensure it is correctly set. If the image is still blurry, try adjusting the lighting or the contrast settings to improve clarity.
How do you view specimen under high power on a microscope?
To view a specimen under high power on a microscope, first ensure the specimen is properly mounted on a slide and in focus under low magnification. Then, increase the magnification to high power, typically 400x or higher, using the lens adjustment knob without contacting the slide. Finally, fine-tune the focus using the fine focus knob to get a clear view of the specimen at high magnification.
What are the steps involved in preparing a wet mount of a specimen?
To prepare a wet mount of a specimen, first, place a small drop of liquid (like water or a suitable medium) on a clean microscope slide. Next, using a pair of tweezers, carefully place the specimen in the drop. Then, gently lower a coverslip at an angle over the specimen to avoid air bubbles. Finally, observe the specimen under a microscope, adjusting the focus as needed.
To observe a skin cell through a microscope at highest magnification you should first?
To observe a skin cell at the highest magnification through a microscope, you should first place the skin cell slide on the microscope stage, focus the microscope using the coarse and fine focus knobs, adjust the light intensity, and then increase the magnification to the highest level possible on the microscope objective.
How would you prepare a amoeba specimens for observation?
To prepare an amoeba specimen for observation, you would first collect a sample containing the amoebas. Then, place a drop of the sample on a microscope slide and cover it with a coverslip. Finally, observe the specimen under a microscope, adjusting the focus to see the amoebas clearly.

Which type of microscope would a scientist use to observe a living one celled organism?
A scientist would likely use a compound light microscope to observe a living one-celled organism. This microscope uses visible light to illuminate the specimen and allows for observing living organisms in real-time. Additionally, a phase contrast or differential interference contrast microscope could also be used to enhance the contrast of the specimen without staining.

How is a microscope with slides used?
A microscope slide is the commonest instrument in any Biology laboratory. It is a transparent rectangular glass apparatus and it fits underneath the lens piece of the microscope. It is used for mounting smears of body secretions, microscopic specimen of bacteria, viruses, fungi or parasites. One can stain the specimen they want to observe and focus the microscope on it. A cover slip is placed on top of the slide in order to keep the specimen in place. One can use a microscope slide in order to draw blood films as well.
Why must the specimen be centered before switching to high power on a microscope?
Centering the specimen before switching to high power on a microscope helps ensure that the area you want to observe is in focus and at the center of the field of view. This is important because high power magnification has a narrower field of view and lower depth of field, making it more challenging to locate and focus on the specimen if it is not first centered.
How do you prepare specimen for stereo microscope?
To prepare a specimen for a stereo microscope, first place it on a clean glass slide. If needed, add a drop of water or mounting medium to help stabilize the specimen. Then cover the specimen with a coverslip, to protect it and ensure clearer imaging under the microscope. Finally, position the slide on the stage of the stereo microscope and adjust the lighting and focus for optimal viewing.
Which adjustment knob should be used first when focusing the microscope?
The coarse adjustment knob should be used first to bring the specimen into general focus. Then, the fine adjustment knob can be used for precise focusing.
What was the first specimen to be placed under the microscope?
The first specimen to be placed under the microscope was likely a thin slice of cork viewed by Robert Hooke in the 17th century. This led to the discovery of "cells" and marked the beginning of modern microscopy.
Who used a microscope to observe slices of cork?
Robert Hook was first to look through a microscope to observe slices of cork. He described these as "boxes", later came to know as "cells".
