How do you measure elongation of tension specimen?
The elongation of a tension specimen can be measured by marking a gauge length on the specimen before testing it and then comparing the final length of the specimen after it has been stretched to the original gauge length. The elongation can be calculated using the formula: Elongation = ((final length - original length) / original length) x 100%.
Does a fresh specimen go in formalin?
Yes, a fresh specimen can be placed in formalin for fixation and preservation before processing for histological analysis. The formalin helps prevent degradation of tissue structures and maintain their integrity.
The specimen must be centered in the field of view on low power before going to high power?
Centering the specimen on low power magnification helps ensure that it remains in focus and does not move out of view when switching to high power. This practice also allows for a better understanding of the specimen's overall structure and orientation before examining it in greater detail on high power.
How do you prevent contaminating a specimen with extraneous micoorganisms?
To prevent contamination of a specimen with extraneous microorganisms, maintain a sterile working environment, use proper aseptic techniques, and handle the specimen carefully to avoid contact with surfaces or airborne contaminants. Additionally, ensure that all equipment used is properly sterilized before use.
Why is it important to center a specimen on low power before attemping to focus on it at high power?
Centering a specimen on low power ensures that it is within the field of view and makes it easier to locate and focus on at high power. If a specimen is not centered on low power, it may be difficult to find and focus on when switching to high power, leading to potential damage to the specimen or microscope lenses. Additionally, centering the specimen helps to achieve the best image quality and clarity at high magnification.
What happens if you did not center the specimen before moving to higher?
If you do not center the specimen before moving to higher magnifications on a microscope, the specimen may move out of the field of view or become difficult to find at the higher magnification. This can lead to difficulties in focusing and observing the specimen accurately. It's important to center the specimen at lower magnifications before moving to higher ones to maintain a clear view.
How old must a tire be before its discarded?
There is no specific age, it is more to do with wear.
Why must the specimen be centered before switching to highpower in a microscope?
Centering the specimen before switching to high power helps ensure that you are viewing the area of interest in focus. It helps prevent the objective lens from hitting the slide, which can damage both the lens and the specimen. Additionally, centering the specimen can improve the image quality by reducing glare and shadowing.

Why the specimen should be dried before positioning and mounting?
Because it will change shape as it dries, so mounting it while it is wet would cause excessive stresses.
Why is it necessary to take note on the color of the specimen before drying or before soaking it in faa solution?
There are a few reasons for this. First, the color can give you an indication of the health of the specimen. If the specimen is very pale, it may be sick or dying. Second, the color can give you an indication of the age of the specimen. If the specimen is very young, it will be a different color than if it is older. Finally, the color can give you an indication of the sex of the specimen. If the specimen is male, it will be a different color than if it is female.
Which type of urine specimen is needed to detect an infection?

Should a potentially good idea in any realm of society be given a fair evaluation before it is discarded?
A potentially good idea in any realm of society should be given a fair evaluation before being discarded, but unfortunately there are a lot of ideas too little time for this to be reasonable.
Why should you air-dry a specimen before heating in laboratory experiments?
You should air-dry a specimen before heating it in the labratory in order to get rid of any impurities. Also, it helps you record the best and most accurate figure while heating.
