Focusing a specimen under low power objective (LPO) allows you to find and center the specimen on the slide before moving to higher magnifications. This ensures that the sample is in the field of view and helps in adjusting the focus and moving to higher magnifications without losing sight of the specimen.
What else can I help you with?
Why do you need to fucos specimens under LPO first before focusing under the HPO?

Why do you need to add iodine solution to a specimen?
Iodine solution is commonly used to test for starch. If starch is present in a substance (e.g. a leaf which undergone photosynthesis) then the iodien solution would turn blue black. If no starch is present then it remains as light brown.
How do cats breath when under blankets for hours?
They need a much smaller quantity of air and the pockets under the blanket are sufficiently large.
How do you stop your puppy from doing things behind your back that she knows she is not supposed to do?
First things first: Your puppy does not know she is not supposed to do something. A puppy is like a toddler; if you don't tell a toddler that she can't reach under the sink where the chemicals are kept, she is going to think she is allowed under the sink. If you don't train your puppy to use the bathroom outside or to not chew up the furniture, she is going to think it is okay to do these things. Basically, you need to train her not to do what she is supposed to "know" not to do.
Why does a lion have stripes?
this white you see under the eyes , is used in the way at night to draw light from the night sky starts moon any light and focus on the pupil and makes them see better during the night as they are night hunters and need as much light as possible its the same as why does uyour car have lights.
What should you bring when using a specimen into focus?
When using a specimen microscope, it is important to bring the specimen into focus by adjusting the focus knob until the specimen appears clear and sharp under the objective lens. You may also need to adjust the light intensity and diaphragm to enhance the contrast and visibility of the specimen. Additionally, ensure that the slide is clean and free of any debris that may obstruct the view.
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.
Why is it important to focus specimens under the Low Power Objectve before observing it under the High Power Objective?
It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing. It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.
Why do you cut a very thin slice of specimen to look under light microscope?
Cutting a thin slice of the specimen allows light to easily pass through the sample and provides a clearer image under the light microscope. A thin slice also ensures that the entire specimen can be viewed at once, without the need to focus on different depths. This method helps in obtaining detailed and high-quality images of the sample.
Why shouldn't you use the course adjustment knob when viewing the specimen under high power?
You shouldn't. You can cause the high objective to smash into the surface of the slide and crack it. Always use the fine adj. for high power and if you cannot get the high power in focus, reverse out to low again and do it over. Ideally, if you are in focus on low, you should be in focus at medium (may have to adjust a small amount) and if you are in focus under medium, when you swing the high power obj. into place, it should be in focus as well (may need a fine tune). Always reverse out and start all over again if you cannot focus it under high power. Deja Was Here
Do you start with the lowest power lens on a microscope first?
Yes, it is best to start with the lowest power lens when using a microscope. This allows you to locate and focus on the specimen before moving to higher magnifications. Starting with a higher power lens can make it harder to locate and focus on the specimen.
What is the first magnificationused to look at a slide?
You start with the lowest magnification. Once you have found the specimen and focused it, you can move it to the next higher magnification. It should still be in focus, although you might need to use the fine adjustment.
If after focusing in low power only the fine adjustment need be used to focus the specimen at the higher powers the microscope is said to be?
parfocal. This means that once the specimen is in focus at a lower magnification, it will remain nearly in focus when changing to a higher magnification, requiring only fine adjustment to sharpen the image.

Why a specimen need to be viewed under the microscope must be thin?
Specimens need to be thin to allow light to pass through them and be able to observe details and structures at a cellular or subcellular level. Thicker specimens would block the light and hinder the ability to visualize the specimen clearly under a microscope. A thin specimen also helps to reduce scattering and distortion of the image.
Why does the specimen on a microscope small?
Microscope specimens need to be small in order to allow light to pass through and be focused onto the eyepiece. Additionally, smaller specimens enable the microscope to magnify them effectively, making it easier to observe fine details. A smaller size also helps to ensure that the entire specimen remains in focus under the lens.
