Not all oral bacteria are gram negative, but those that are there can be seen with Gram stain.
Because it is a Gram-negative bacterium and can be stained with Gram-negative stain.
A bacterium is typically thousands of times smaller than a man in terms of size. Bacteria are microscopic organisms that can only be seen under a microscope, while humans are multicellular organisms that can be seen with the naked eye. The size of a bacterium can vary depending on the species, but they are generally much smaller than humans.
Will proper staining and the right organism the nucleus of a cell can be seen without an electron microscope.
Flagellar staining is a specialized technique used in microbiology to visualize the flagella of bacteria, which are essential for their motility. This method involves applying specific dyes or stains that bind to the flagella, allowing them to be seen under a microscope. Since flagella are often too thin to be observed with standard staining techniques, flagellar staining helps in identifying and classifying bacterial species based on their flagellar arrangement and structure. The technique is crucial for understanding bacterial behavior and pathogenicity.
Although mycoplasma lack a cell wall and therefore test gram negative, they are considered to be descendents of 'nonsporulating and endospore forming gram-positive bacteria' (Madigan et al., 2009), such as Lactobacilli, Bacilli and Streptococci, (Dandekar et al., 2002), which have lost their cell wall. Mycoplasmas are therfore classed as gram- positive bacteria. This is supported by ribosomal RNA and DNA analysis.
Because it is a Gram-negative bacterium and can be stained with Gram-negative stain.
Bacterium are not invisible, but they are microscopic, meaning they can only be seen under a microscope at higher magnification. A bacterium can be transparent, but they can usually still be seen by the outline of their body, but, again, all bacteria can only be seen under a microscope.
Gram negative diplocci is the name given to describe the structure and shape of the bacteria, Neisseria gonorrhoeae (the infective organism of the STD gonorrhea) as it is seen on the microscope using a technique call gram staining.
Negative stain microscopy is similar to bright-field microscopy in terms of creating contrast between the specimen and the background, but it uses an opposite staining technique. Instead of staining the specimen, negative staining stains the background, leaving the specimen unstained and appearing as a bright object against a dark background.
Yes I have seen the tooth fairy in action.
The nucleus is an organelle that can be easily seen with a microscope due to its dark staining and distinct structure within a cell.
poo grows on it :>
The Tooth Fairy is whatever colour you want her to be. No one knows because no one has ever seen her.
Yes, I have seen someone who is too skinny

No actually when they come out the tooth fairy takes them to a remote location where they blow up and will never be seen again.
They won't freak out. They've seen babies being born, they've seen you throw up (or your siblings) they've seen you naked, they've been through everything.
