Why do scientists get the thinnest possible sample to look at in a microscope?
Scientists get the thinnest possible sample to look at in a microscope in order to reduce light scattering and distortion, which can result in clearer images with higher resolution. Thinner samples also allow for better visualization of fine details and structures within the specimen.
What do you call the thing you look at under a microscope?
The specimen or sample being examined under a microscope is typically referred to as the "specimen." This can be anything from cells, tissues, or other material being studied or observed under the microscope.
What kind of microscope is used to look at a Petri dish?
A stereo microscope or a dissecting microscope is commonly used to view objects like a Petri dish as they provide a lower magnification but higher depth of field compared to compound microscopes. This allows for a 3D view of the sample.
What is the best way to look at fish and chicken skin cells under a microscope?
The best way to look at fish or chicken cells would be to obtain a very thin slice of tissue and mount it on a slide. This can be viewed using an inverted microscope found in most tissue culture laboratories. A simpler alternative to prepare the sample would be to take a small piece of tissue and grind it in between two glass slides. This can be done with gloved hands and regular microscopic slides. The flattened tissue can be placed under an inverted microscope and the cells can be viewed at either 40X or 100X magnification
Why do you have to use NSS instead of water in preparing fecal smear?
NSS (normal saline solution) is used instead of water in preparing a fecal smear to prevent lysis (rupturing) of red blood cells in the sample. Using water can cause hemolysis, which may interfere with the accurate interpretation of the fecal sample. Normal saline is isotonic and helps maintain the integrity of the red blood cells in the smear.
How would someone test their blood type?
First pinch the finger with pricker and take a blood sample. Take the sample and get an acid. Put your blood and look at the sample reaction then look for any difference.
What is a microscope slide and what is it used for?
A microscope slide is a small rectangular piece of glass that the sample (the thing you're looking at) is placed on for observation. Generally, the sample is next covered with a cover strip (a small piece of plastic, used to keep the sample from sliding). The slide makes it possible to look at the sample. Otherwise, the sample would fall into the microscope light, which would be a little inconvenient.
What criterion is used to identify reticulocytes?
A blood sample is observed under a microscope using a stain or dye which will cause the RNA of the reticulocyte to be visible. Reticulocytes also look larger than mature red blood cells.
Why are the stains on an electron microscope lead or gold?
You can look at any type of sample under an electron microscope. Depending on the sample, it can handle a certain amount of electrons on the surface (from the microscope). After this limit is reached, no image from the microscope can be obtained. This is because electrons can no longer "stick" to the sample and they start flying around crazily. Coating the sample with another substance, such as gold or lead, will allow the sample to handle a greater amount of electrons. The larger the amount of electrons on the surface, the finer the details one can obtain from their sample.

What are the various appratus used in heamatology lab?
Generally it would have a microscope to look at the cells under magnification and a blood cell analyzer that looks at the percentage of cells and the type as well as stages of development. There would also be a slide maker and stainer so you can look at the cells under the microscope. Most modern labs have an automated machine to look at blood coagulation which looks at the time it takes blood to clot.
What do you look through in a microscope?
Any organic substance or sample thin enough to let light through.
How is leukemia tested?
The most informative test for Leukemia is a Bone Marrow Aspiration. A needle is inserted into the pelvic bone and a sample of bone marrow is extracted (aspirated) . That sample is sent to a laboratory and is looked at under a microscope to look for bad blood cells and other signs of leukemia.
What do you look through in a light microscope?
Any organic substance or sample thin enough to let light through.
How big would the specimen look?
the specimen is the objective the microscope and a parts of microscope

Would you use the electron microscope or the compound microscope to look at cork?
---- You would use the light microscope. The electron microscope would be unnecessary in this situation, due to its high magnification levels.
