Why is it necessary to be able to focus a specimen at different depths on the microscope?
because the subject may have different charactreistics at different depths
Why must the course adjustment knob be turned forward only while watching from the side?
The course adjustment knob must be turned forward only while watching from the side to ensure that the microscope's objective lens moves closer to the specimen. This allows for focusing on the specimen and achieving a clear image. Turning the knob in any other direction may result in moving the objective lens away from the specimen, leading to an out-of-focus image.
Why it is necessary to be able to focus on different depths on the microscope?
Each depth will show different parts of whatever you are looking at on the microscope. The focus improves when using the right depth and magnification.
When looking at a slide under the microscope you should always put the stage at its highest point near the lens and then move it away until it comes into focus why is this a good practice to follow?
So you don't damage the lens by crushing the slide into it.
When beginning to focus the lowest-power lens should be used?
true
What structures on the microscope will you used to focus on your specimen?
First use the coarse focus followed by the fine focus.
What two structure on the microscope will you use to focus on your specimen?

How should you first focus on a specimen when using the microscope?
start by focusing with the lowest lens to make sure the slide is right and you can see the specimen them proceed to the next lens power and focus again just to make the view clear then proceed to the highest and focus one more time

When a very close view of the specimen is necessary. You can focus in on one part of the specimen.

Each thread layer comes into focus separately because the specimen is three-dimensional (it has thickness). By moving the fine adjustment knob back and forth, the layers of the specimen will come in and out of focus.

hehehehehehe i don/t know

FOCUS

To focus the image of the specimen
Which activity might lead to damage of a microscope and specimen?

What two structures on the microscope will you use to focus on your specimen?
eye piece, lens and fine adjustment, focus adjustment
What is the function of the focus of microscope?
