Dead specimens must be used with transmission electron microscopes because living cells are easily damaged by the high-energy electron beam used to create the image. Dead specimens can be fixed and stained to preserve their structure for imaging without being affected by the electron beam. Additionally, dead specimens allow for more control over sample preparation and consistency in imaging.

What reason best explains why dead specimens must be used with transmission electron microscopes?

Dead specimens must be used with transmission electron microscopes because living organisms would be damaged or destroyed by the high-energy electrons used to create images. The electrons can penetrate through living tissue, causing damage and altering the structures being observed. This means that only fixed and preserved specimens can be used safely for imaging with this technique.


What is the name of the theory that explains brown's observation?

The name of the theory that explains Brown's observation is the kinetic molecular theory of matter. This theory states that all matter is composed of particles (atoms or molecules) that are in constant motion, and explains the behavior of gases, including diffusion, pressure, and temperature.


What evidence indicates that electrons move around the nucleus in definite pathways?

the evidence is that when you look through microscopes you can see the different atoms and see the parts of them


What is the scientific theory behind cell theory?

Cell theory states that all living organisms are composed of one or more cells, cells are the basic unit of structure and function in an organism, and all cells come from pre-existing cells through cell division. This theory is supported by multiple lines of evidence from observations made using microscopes and other scientific tools.


Bacteria were first seen in 1683 but viruses were not seen until 1938why?

Bacteria are much larger than viruses and can be seen under a light microscope, which was available in the 17th century. In contrast, viruses are much smaller and can only be seen with the invention of the electron microscope in the 20th century, leading to their discovery in 1938. This difference in size and technology needed for visualization explains the lag in discovery between bacteria and viruses.

Is there a unified theory explaining all correlated electron systems?

There is no single unified theory that explains all correlated electron systems.


Does faradays law of electromagnetic induction explains wireless transmission of electricity?

not entirely, you need Maxwell's equations for a complete explanation

Transmission relearn procedure for 1997 Saturn car?

Go to www.valvebodybuilders.com/tech_saturn_relearn.html that worked when I replaced my vavle body.it explains why and how to relearn TATT tranny.


Where can one find the procedure to change the transmission fluid on a car online?

The DMV Org (a private company) offers a great article which carefully explains the procedure one would use when changing the transmission fluid on their own. You can view it online from their website.


Where is the automatic transmission drain plug on a 2004 Honda Pilot?

Look under the front of the Pilot. The drain plugs for the transmission and engine are both under the front and both have labels next to them marked ENGINE OIL and TRANSMISSION OIL. I suggest you get the Haynes manual for the Honda Pilot which explains how to do all this easily. Good luck.


Which property of chlorine explains why it is likely to form a compound with an alkali metal?

Chlorine has a high electronegativity, meaning it has a strong tendency to attract electrons. This property makes it likely to form a compound with an alkali metal through ionic bonding, where the alkali metal loses an electron to chlorine to achieve a more stable electron configuration.


Why is the VSEPR model mainly?

The VSEPR (Valence Shell Electron Pair Repulsion) model explains molecular geometry based on the repulsion between electron pairs in the valence shell of an atom. It is mainly used because it is simple, intuitive, and provides a good approximation of molecular shapes based on the number of bonding and nonbonding electron pairs around a central atom.


Which explains the change in ionization energy that occurs between removing the first and second electrons from an atom?

The ionization energy increases when removing the second electron because the remaining electrons experience a higher effective nuclear charge due to the removal of the first electron. This makes it harder to remove a second electron compared to the first one.


What model explains the behavior of light passes through a polarizing filter?

Malus's Law explains the behavior of light passing through a polarizing filter. It states that the intensity of light transmitted through the filter is proportional to the square of the cosine of the angle between the filter's transmission axis and the light's polarization direction.


Which models of the atom reflects the unpredictable motion of the electron?

The Bohr model and the quantum mechanical model both reflect the unpredictable motion of the electron in an atom. The Bohr model introduced the concept of quantized energy levels for electrons, while the quantum mechanical model treats electrons as having both particle and wave-like properties, leading to uncertainty in their position and momentum.
