What else can I help you with?
Can the electron microscope be used to study a live specimen and why?
Not really. An electron microscope requires that the specimen be placed in a vacuum for viewing. It would most certainly kill any living creature placed inside it. No, the specimen being viewed is incapible of life after being placed into the slit.
Is it true or false that chloride ions are chlorine atoms that have lost a single electron?
False. A chloride ion is a chlorine atom that has gaineda single electron.
Alkali metals lose an electron to form a stable octet. true or false?
False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
If the outermost electron shell of an element is not filled with electrons to its maxium capacity the element is not chemically active?
false
Is this True or false cells were discovered using electron microscopes?
False. Cells were first discovered by Robert Hooke in 1665 using a light microscope, long before electron microscopes were invented. The development of electron microscopes in the 20th century allowed for greater detail and resolution when studying cells.
When focusing on a specimen do you always focus toward the specimen?

Were cells discovered by an electron microscope?
cellls were discovered by an electron microsopeKayla Millerokay first of all idk the question was a true or false question for this teacher mr.greenlee at severn river middle school. we have a test so i was just wondering what the answer was but i like Kayla miller's answer but u need to improve on it so some people can get a better understanding of what ur talking about
Is the following sentence true or false most viruses are so small that they can be seen?
False. Most viruses are so small that they cannot be seen with a standard light microscope. They are much smaller than bacteria and are typically observed using electron microscopes.
Is the following sentence true or false hydrogen servers as the final electron acceptor of the electron transports chain?
False
Why are electron micrographs always in black-and-white?
Electron micrographs are typically in black-and-white because electron microscopes use electrons to produce images, which do not have color. The electrons interact with the specimen to create contrast, resulting in a grayscale image. Although false color can be added to highlight different structures, the base image is still in black-and-white.
Hydrogen serves as the final electron acceptor of the electrons transport chain true or false?
False. Oxygen serves as the final electron acceptor of the electron transport chain.
What true or false the medical assistant does not need to worry about contamination because the specimen has already been exposed to a pathogen?
False
Transmission electron microscopes form a 3-d image of the surface of a specimen?
Transmission electron microscopes primarily visualize the internal structures of specimens in two dimensions by passing a beam of electrons through the sample. The images produced are highly detailed and provide information on the ultrastructure of the specimen, but the technology does not directly generate 3D images of the surface. Advanced techniques like tomography can be used to reconstruct 3D structures from TEM images.
When an atom gain an electron its becomes a positive ion true or false?
false
A region in which there is a high probability of finding an electron is called a field true or false?
False. A region in which there is a high probability of finding an electron is called an orbital in quantum mechanics, not a field.
