Can you detect ribosomes if you're using an up-to-date light microscope to examine animal cells?
No, you cannot.
What organic molecule is necessary to detect mixed acid fermentation by bacteria?
glucose
If youre using an up to date light microscope to examine animal cells you wont be able to detect what?
ribosomes
Which of the activities is not a response of human white blood cells to disease?
Speeding transmissions of nerve impulses to detect these bacteria- Iroda Juraeva
Why were the S bacteria not the R bacteria virulent?
The S bacteria are surrounded by a capsule, so it is not engulfed by the host's white blood cells. That means that it is able to proliferate and spread. The R bacteria lack the capsule (like the mutant S bacteria), so the white blood cells are able to detect and eliminate them.
What is the electron microscope used for?
The electron microscope is used to see cells and other miniscule objects that are too small for light microscopes. It shoots electrons to detect the shape of the object viewed under the microscope. It can magnify up to 2 million times, while the best of light microscopes are confined to about 2000 times.
How can viruses be seen?
Viruses are incredibly small - much smaller than the smallest of bacteria, even though many millions of bacteria could fit on a pinhead. Therefore viruses can only be seen with the help of a very powerful microscope such as a scanning ellectron microscope.
Why you need to use a electron microscope to examined a virus?
because viruses are very small and can not seen by any light microscope.only electron microscopes that use electron radiation that have wavelenght about .005 nanometer have enough resolving power to detect such a small particles as viruses

Is the universe an electron?
An electron is very small. So small that you cant even see it with an electron microscope (because it uses electron to detect itself). It's mass is tiny. Billions of times less than a kg. It's just one type of matter. Some estimates put the number of electrons in the universes at greater than 10100. So no, the universe is not an electron.
What can you see with a microscope?
The microscope is an optical instrument used to view objects or particles that cannot be seen through our naked eyes. It is also used by medical technologists to detect certain bacteria, parasites, or other foreign elements in the specimen of an individual.
What instrument can be used to detect electron flow?
Amperemeter (or Ammeter)
Can you detect mitocondria using a light microscope?
Most likely, no. I've tried, no results. Well, maybe, if the microscope is strong enough.
If you're using an up-to-date light microscope to examine animal cells you won't be able to detect?
you wont be abale to detect ribosomes
What can a light microscope do?
it employs light to detect small objects and make them appear bigger
What is the role of immune electron microscopy in viral diseases?
can be used to detect and identify viral particles that have too low concentration to be detected using conventional electron microscopy. binding of antibodies to the viral particles makes them easier to detect.
What is an advantage of using an electron microscope?
Answer: Using an EM (electron microscope) you can look INSIDE a cell and take photos. This is different to an ordinary (or Light microscope) where you generally only see the outside of the cells - or at best can only see vague shapes inside the cell. Answer: The scanning electron microscope provides a number of advantages over an optical microscope. Primarily this centers around the fact that the wave lengths used are much smaller than the wavelengths of light. What you can see is, in par,t dependent on the relative size of the object and wavelength of the light you are using. For very small objects, like individual atoms, light just wont work. Secondly the electron microscope can be fitted out with equipment and analytical sensors to identify the atomic composition of materials in the field of view. These Scanning Electron Microscopes (SEM) are extremely useful in identifying trace contaminants. The standard microscope still has advantages. It can detect the polarizing capacity of organic compounds, it is cheap and easy to use, it can be used in the analysis of stained samples in microbiology, it can use transmitted light and reflected light to examine an object. A major advantage is that the surface of the viewed object does not have to be prepared by being covered with a very thin layer of metal to permit viewing.
