How a microscope could be used to determine if the specimen is a living thing?

Technology is used... such as heat sensors you cant tell just by looking through a microscope you have to use technology... unless of course it moves and multiplies or you recognize cells. (The latter requires that you have a pretty good idea of what cells look like.)

How you could use a microscope determine whether the specimen is a living or non-living thing?
You can tell because it will show characteristics of a living or nonliving object.
Can a scientist observe living things under an electron microscope?
Specimens are placed in a vacuum (high vacuum, requiring a cryopump to get to 10^-7 torr. Then the specimen is bombarded with an electron beam (like getting a shock). Not likely that something could survive that.
What is the objective lens on a microscope?
An optical microscope used in a laboratory would have 3 different types of lenses.They are :-(1) Condenser lens- directs light to the specimen if there is no in built light source.(2) Eye piece - lens close to the eye of the observer which magnifies the image created by the objective lens.(3) Objective - These are the lenses which are positioned closest to the specimen mounted on the stage of the microscope which magnifies the specimen. There could be several objective lenses in an optical microscope, generally three. The low power objective (usually magnifies 4 times), mid power objective (usually magnifies 10 times) and the high power objective (usually magnifies 40 times).
Why do specimens need dehydration to be viewed under a light microscope?
If they were not dried well then any water on the specimen could refract or reflect the light coming at it...and so distorted images would be the result.
What can you study with a light microscope?
dead organisms and their parts, and to observe some tiny organisms and cells while they are still alive :) +++ Also used in many other branches of science, medicine and engineering. ,
How could you use a microscope to help determine whether the specimen is living or non-living thing?
wouldn't it be moving?

Why is it important not to have the light intensity setting too high on a light microscope?
It could burn and melt the specimen
What is the maximum power of magnification of a microscope?
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.

Could you study the structure of DNA in a living specimen?
Yes. Scientist Wardisiani proved it
What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
What will you never see in an unretouched electron micrograph?
I need the same answer!!! What I could find in my book is that unlike the optical microscopes, electron microscopes use a vacuum so there can be no living specimen. So no living specimen is my final answer.
Summarize information about electron microscopes using five or six bullet points?
1. electron microscope could magnify until 200,000 and have high resolution 2. they cannot be used on living organisms because it enters a vacuum so electron don't bounce off a gas molecule 3. it allow you to view molecule 4. electron microscope is a beam that hits a specimen and hitting back to draw the molecule in the fluorescent screen this is called transmission electron microscope 5. there is a scanning electron microscope that scans specimen coated by a thin layer of metal ions that bounce back forming 3-D image
What is the Instrument used to see small details of specimen?
I magnifying glass and if it's even smaller, you could use a microscope and maybe horoscope
What is the purpose of a mirror in a microscope?
The purpose of a mirror is to reflect light through the diaphragm, the specimen, the objective lens, and body tube and into your eye so you can see the image. Never use sunlight when using a microscope with a mirror, as it could damage your retinas.
