What else can I help you with?
What are two types of electron microscopes?
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.
What is the overall of an atom?
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.
The type of electron cloud around the nucleus that shows the possible electron positions?
well i think it is the electron cloud
What is an electron or particle similar to an electron emitted from the nucleus with negligible mass and a charge of -1?
In this context, we call an electron a beta particle.
The farther an electron is from the nucleus the?
The farther an electron is from the nucleus, the greater its energy.
What is the photograph taken from using an electron microscope called?
The image taken from an electron microscope is called an electron micrograph or simply a micrograph. It provides a highly detailed and magnified view of the specimen being studied.
What is the name of electron microscope images?
Electron Micrograph
What is the name of a photograph taken by an electron microscope?
Electron micrograph
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.
What are the highly condensed portion of chromatin which appear as very dark areas in a transmission electron micrograph?
which is the loosely condensed chromatin where genes are expressed
Why adding colour to an electron micrograph can help biologists communicate information about the image?
Adding color to an electron micrograph can help differentiate different structures or components within the image, making it easier for biologists to interpret and communicate information. Color can also enhance contrast and highlight specific details, allowing for a clearer and more detailed representation of the sample being studied.
What parts did you identify?
The cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes are easily visible in this transmission electron micrograph.
What cell parts did you identify?
The cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes are easily visible in this transmission electron micrograph.
Can live speciments be examinednwith an electron microscope?
No. The is the big drawback to SEM and TEM microscopy, the subjects must be fixed to the slide, fractured or some other preparation method and this means they must be dead.
How can you see the parts of a cell?
You can see parts of cells by microscopy.A light microscope will reveal detail with a resolution down to about 0.2 micrometers. More detail becomes visible using various techniques, such as staining or phase contrast microscopy.An electron microscope improves the resolution to about 2 nanometers. What is seen in an electron micrograph is the shadow left by heavy metal atoms in the stain, which has attached to cell structures.

What is freeze etching method?
Freeze etching is a method used in electron microscopy to reveal the internal structure of biological samples. The sample is rapidly frozen, fractured, and then sublimated to remove ice, exposing the internal surfaces. This technique allows for high-resolution imaging of cell membranes and other cellular structures.
