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.

Why is bacillus anthracis a biological weapon?
Bacillus anthracis is considered a biological weapon due to its ability to form highly resistant spores that can be dispersed in the environment easily. When inhaled, ingested, or coming into contact with open wounds, these spores can cause severe, often fatal, anthrax infection. Additionally, the bacteria can be engineered to be more virulent and resistant to treatments, increasing its potential for use as a weapon.
Robert koch use what microorganisims to formulate koch postable?
Robert Koch used Bacillus anthracis, the causative agent of anthrax, to develop his postulates. These postulates are a series of criteria used to establish a causative relationship between a microorganism and a disease.
What would be the easiest microscope to use whenever you are looking at cell membranes?
The easiest microscope to use for observing cell membranes is a fluorescence microscope. This type of microscope allows for the visualization of specific proteins or lipids in the cell membrane by using fluorescent dyes or tags, which can highlight structures that may be difficult to see with traditional light microscopes. Fluorescence microscopy also provides better contrast and resolution for cellular components, making it ideal for studying dynamic processes in living cells.
What is Anthrax Powder?
Anthrax powder refers to a finely milled form of anthrax bacteria that can be weaponized for use in biological warfare. When inhaled, ingested, or absorbed through the skin, it can cause severe illness and potentially be fatal. Due to its potential for harm, anthrax powder is classified as a bioterrorism agent.
Advantage and disadvantages of fluorescence microscope?
It is easier to view because it already has a light source. *Basically you can not use living tissue with Electron Microscopes, but only Light compound ones. "Because electron microscopes require a vacuum to operate samples must e preserved & dehydrated before they are placed inside the microscope. Meaning that living cells cannot be observed with electron microscopes, only with the light ones."
What kind of agent use to kill bacillus anthracis?
Autoclaving
How do you use bacillus in a sentence?
Bacillus are the type of bacteria which are causative agents of food poisoning. e.g. Bacillus Anthracis
How does the use of a dichroic mirror enhance the performance of fluorescence microscopy?
A dichroic mirror enhances fluorescence microscopy by selectively reflecting and transmitting specific wavelengths of light. This allows for better separation of excitation and emission light, resulting in improved image quality and contrast in the final fluorescence image.

Why is a condenser not used in epi-flouresence microscopes?
A condenser is not used in epi-fluorescence microscopes because the excitation light is focused onto the sample from above, typically through the objective lens. The use of a condenser, which typically directs light from below the sample, is not necessary in epi-fluorescence microscopy as it would not contribute to the desired illumination and would interfere with the fluorescence detection.
When was anthrax discovered?
Robert Koch- German

Can you use a C18 column for HPLC with fluorescence detector and methanol as the mobile phase?
Yes, you can use a C18 column and methanol as a mobile phase with fluorescence detector. Fluorescence detector is generally used as it can detect the presence of compounds at a very low concentration.
What has the author W G Hartley written?
W. G. Hartley has written: 'How to use a microscope' -- subject(s): Microscopes, Microscopy 'The light microscope' -- subject(s): History, Microscope and microscopy, Microscopy
What type of microscopy does not use light?
Electron microscopy; Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM). The vacuum required for electron microscopy to work correctly precludes the observation of living organisms. Biological samples must be dried then coated with a conductive metal.
What are the purposes of bright field microscopy?
The purpose of bright field microscopy is to provide a simple, yet effective, technique for use in observing microscopic properties of samples.
