Why use fluorescence microscopy for bacillus anthracis?
Perhaps fluorescence would be used because B. athracis has a cell wall making it difficult to visualize the details of the cytoplasm by simple bright field microscopy. Flourescence allows for labeling of specific entities, and "cold" illunimation of those entities against a dark field.
What determines which variations are selected for or against?
The ability of those variations to survive and be reproductively successful against other variations in the immediate selective environment. The coin evolution pays in is reproductive success.
What microscope shows cells against a bright background and also shows intracellular structures of unstained cells based on their varying densities?
bright-field
Why you use serum of animal against which your secondary antibody is raised for blocking the membrane?
It prevents non-specific binding of the secondary antibody, and thus reduced background.
Why planet are called planet?
Planet comes from an ancient Greek term meaning 'wanderer'. They were called wanderers because they appear to move against the apparent stationary background of stars.
What concept of microsopy deals with the ability of the specimen to stand out against its background?
"Contrast is how well a specimen stands out from the background."
What type of microscopy is the negative stain similar to?
The darkfield microscope. "darkfield microscopy"
What is darkfield microscopy?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

When was Against a Dark Background created?
Against a Dark Background was created in 1993.
How many pages does Against a Dark Background have?
Against a Dark Background has 487 pages.
How should the condenser be set when viewing bacteria?
The condensor of microscope is used to control the light intensity so it first depends on the viewer and secondly it should be so adjusted so that the light intesity does not shoots high as it can damage the specimen and is also harmfull to the eyes and even to the microscope. It is also to be see that the specimen view clearly against its background.
How are noroviruses diagnosed?
Norovirus from fecal samples can be visualized using electron microscopy. With immune electron microscopy (IEM), antibodies against norovirus are collected from blood serum and used to trap and visualize the virus from fecal samples.
When was Peasant Woman Against a Background of Wheat created?
Peasant Woman Against a Background of Wheat was created in 1890.
