The coarse adjustment knob should never be used when viewing in high power with a compound microscope. When in high power, use the coarse adjustment (the knob smaller than the coarse adj.) to more accurately focus on the subject.

Why must initial focusing of an object be under the low power objective and not under the high power objective?
Low power objective is like our eye if we want to see we can just see normally but if we want to see something very small but want to see properly at that particular part then we always go for some lens of something powerful. That's the same thing when we want to know something deeply we go for high power microscope to read a more detailed study of a particular part of object under the microscope.
When focusing a specimen you should always start with which objective?
Ocular Lens (eyepiece) or Stage
What is the name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?
I assume you would use the fine adjustment knob for high power objectives.
What happens to the depth of field as your move from low power to high power?
Depth of field decreases from low to high. This means what you see under the microscope is blurry. If both objects are not blurry, this means you have high depth-of-field.
What are some of the advantages of viewing cells under high power?
you'll see more detail of the cell
What are the dangers of using the coarse-adjustment knob when focusing under high power?
It is possible to cause damage to the microscope or lenses when using the coarse focus- such as pushing the lens through the glass slide.

How does the working distance change when you go from low power to high power magnification?
it is how you operate the microscope just adjust he course adjustment knob for focusing the fine adjustment knob
What is the lens that is used to find the specimen on a microscope?
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
How do you view specimen under high power on a microscope?
the same way as under low-power on a microscope: carefully
What is the difference between the field of view under high and low power?
You can see less under high power because it focuses on a smaller part of the specimen, but in more detail than low power.
What is the name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?
I assume you would use the fine adjustment knob for high power objectives.
Does the switch from low power to high power change the position of the image under microscope?
No it does not
Are both hair focused under high power magnification?
No.
Which activity might lead to damage of a microscope and specimen?
using the course adjustment to focus the specimen under high power
Why should you examine the root tip under high and low power?
The high power is because so you can see it u close and the low power is further away.
