Why a drop of water is added to the onion cell before it is covered with a cover slip?
prepared by adding water to the specimen which increases its translucency and makes it easier to stain. It also has a tendency to cause the specimen to flatten which makes the specimen easier to view.
When should the high power objective be used?
When a very close view of the specimen is necessary. You can focus in on one part of the specimen.
What is a stain and what does a stain do when using one to view objects in the microscope?
A stain is a chemical that enhances the contrast ratio of microscopic items, such as individual structures in cells, so that those structures can be more readily observed in the microscope. The structures absorb the stain at different levels, making them stand out in the viewing field.
As the magnification increases what decreases in a microscope?
The visibility of the specimen decreases as the power of magnification increases on a microscope. The specimen area will shrink as the magnification is increased.
What type of microscope can be used to view non living specimens?
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.
What is a uv transilluminator?
Instrument used to view electroscopic gels and other similar substances on which nucleic acidds may be bound by means of dluorescent dye.

What type of microscope can only be used to view nonliving specimen?
The light microscope and the electron microscope refers to the type of microscope that is used to view the non- living specimen. The non-living specimen is usually placed in a slide.
What is the amount of specimen you are able to see on a microscope called?
if you are reffering to field of view, its not exactly the amount of specimen, its mainly used to determine how large a specimen is
What particular objective should be use when a general view of the specimen is to be used?
When starting a microscopic study,always examine under LPO first.Move the slide and get a good general view of the specimen.
When should the high power objective be used?
When a very close view of the specimen is necessary. You can focus in on one part of the specimen.

What is the function of aceto orcein stain?
Acetic orcein is used to stain chromosomes in a plant cell so that you can view them easily through a microscope.
What objective is used when observing fresh specimen?
The objective of observing fresh specimen is to find out how the still-live specimen functions. One can observe blood flow and movement.
What distortions or artifacts might be seen in electron microscopy when viewing a dried nonliving specimen?
Smaller characteristics of specimens might be seen using electron microscopy to view a dried nonliving specimen. The electron microscope is used to view specimens in great detail.
What type of microscope could be used to study virus?
An electron microscope can be used to view viruses. Scientists can use a negative stain to view bacteria and different types viruses.
How do you adjust the slide when the specimen is out of the field of view to the top?
no
