What else can I help you with?
Is it true or false that early microscopes created by Leeuwenhoek were almost as strong as modern light microscopes?
True. Antonie van Leeuwenhoek's early microscopes were able to achieve magnifications of up to 270 times, which is comparable to the magnification capabilities of modern light microscopes. His innovative designs and techniques allowed for the observation of microorganisms and cells in unprecedented detail.
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.
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.
Cellular respiration does not use oxygen. true or false?
False. Cellular respiration is the process by which cells convert nutrients into energy, and it requires oxygen in the presence of aerobic organisms. Oxygen is used during the final stage of cellular respiration, called the electron transport chain, to produce the majority of ATP (energy) in cells.
Microscopes produce images by focusing light rays and beams of cells true or false?
False. Microscopes produce images by using lenses to magnify and focus light or electrons to visualize objects at a much smaller scale, such as cells or particles.
Are Scanning microscopes used to observe individual atoms?
No. Scanning Electron Microscopes (SEM) use electrons to view microsopic details down to the granular structure of material. Since it uses electrons, it could not detail anything the size of an Atom.
True OR FALSE an electron microscope use light to view the details of a specimen?
False, electron microscopes use electrons to view specimens which have been treated with special metallic "dyes". (the clue is in the name)

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.
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.
Is the following sentence true or false hydrogen servers as the final electron acceptor of the electron transports chain?
False

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.
When an atom gain an electron its becomes a positive ion true or false?
false
