Why must the prepared specimen for a monocular microscope be very thin?
A thin specimen allows light to pass through easily, resulting in clearer and sharper images under the microscope. Thicker specimens can distort the light and make it more difficult to observe the details of the sample.
Why is the specimen prepared for a monocular microscope must be very thin?
The specimen must be very thin for a monocular microscope because light has difficulty passing through thick specimens, leading to poor image quality and decreased clarity. A thin specimen allows more light to pass through, resulting in a sharper and more focused image when viewed through the monocular microscope.
Why is the density of nitrogen prepared in the laboratory less than that collected in the air?
The density of nitrogen prepared in the laboratory is less than that collected from air because laboratory-prepared nitrogen is often in a gaseous state, while nitrogen collected from air may contain impurities or be in a mixture with other gases which affects its density. Additionally, laboratory-prepared nitrogen may be at a higher temperature compared to ambient air, causing it to have a lower density.
What are the advantages and disadvantages of a transmission electron microscope?
Advantages: High resolution for imaging at the atomic scale, capable of studying internal structures of specimens, can image thin sections and ultrathin samples. Disadvantages: Requires a high level of expertise to operate, expensive to purchase and maintain, samples need to be prepared meticulously, and limited depth of field.
How many 5 ml injections can be prepared from 1 liter of medicine?
There would be 200 5 ml injections that can be prepared from 1 liter of medicine. (1000 ml / 5 ml = 200)
Are samples for compound light microscope prepared on glass slides?
Yes
How is material prepared for homeopathic remedies?
For homeopathic remedies, the remedy material is finely ground and then prepared by extensive dilutions. In the early days of homeopathy, silica was prepared from powered rock.
Why is it important for the slide to be prepared so that light passes through it?
If your microscope is a Transmission Microscope then light has to pass through the specimen (that is how the microscope works).Other kinds of microscopes may not require this.
How must samples be prepared for observation by an electron microscope?
Samples for observation by an electron microscope are typically prepared by fixing the specimen in a chemical solution, dehydrating it, and then embedding it in a resin for stability. The sample is then sliced into ultrathin sections using a microtome before being stained to enhance contrast. Finally, the prepared sample is placed inside the electron microscope for imaging.
What is the most basic conducting polymer?
Most conductive polymers are prepared by oxidative coupling of mono-cyclic precursors. Such reactions entail dehydrogenation
How is extracted breast milk prepared for laboratory testing?
The milk is cultured, allowing colonies of bacteria to grow. The causative bacteria then can be specially prepared for identification under a microscope.
What kind of microscope uses two or more glass lenses to magnify either living cells or prepared slides?
A compound microscope uses two or more glass lenses to magnify either living cells or prepared slides. This type of microscope is commonly used in laboratories and educational settings to study cells and microorganisms at a cellular level.
How must samples be prepared by observation by an electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.
What is a prepared slide on a micro scope?
A prepared slide for a compound light microscope is composed of a viewing sample suspended in a drop of distilled water, which has been placed on one glass slide. A second glass slide will be placed on the first slide and any residual water will be gently soaked up by a paper towel.
