Can you determine whether a agar deep culture is pure by visually inspecting it without a microscope?
The short answer is no. Microorganisms are just that - microscopic, and the naked eye can not determine between different species, especially in a broth culture. Maybe on a plate, where the colony shapes, sizes, viscosity, and color can be determined, but a broth culture usually needs to be streaked onto a plate to determine if it is pure or not.

What are the differences between an inverted and upright microscope in terms of their design and functionality?
An inverted microscope has its light source and condenser located below the stage, while an upright microscope has them above the stage. Inverted microscopes are commonly used for observing living cells in culture dishes, while upright microscopes are more versatile for various types of samples.
How inverted microscope work?
An inverted microscope is used for viewing culture vessels. They are constructed with the tip of the objective pointing upward. Like you are viewing the specimen from below. The light is directed on the specimen from above.
What does a culture and sensitivity tube consists of?
A culture and sensitivity tube typically contains a sterile tube with a culture medium to support the growth of microorganisms. The tube is used to collect samples for culture testing, where the microorganisms are identified and tested against various antibiotics to determine the most effective treatment.
How many different bacteria were in the mixed culture?
The mixed culture likely contained multiple species of bacteria, as mixed cultures can consist of various bacterial strains coexisting together. It is difficult to determine the exact number of different bacteria present without further analysis such as culture, staining, or genetic tests.
What are the key differences between an inverted microscope and an upright microscope, and how do these differences impact their functionality and applications in microscopy?
An inverted microscope has its light source and condenser located below the specimen, while an upright microscope has them above the specimen. This difference impacts the types of samples that can be observed and the techniques that can be used. Inverted microscopes are commonly used for observing living cells and tissues in culture dishes, while upright microscopes are more suitable for viewing thicker samples like tissue sections. The choice between the two depends on the specific requirements of the microscopy application.
What sense can easily be used to determine presence of yeast on culture plate?
The sense of sight can easily be used to determine the presence of yeast on a culture plate. Yeast colonies typically appear as small, round, cream-colored spots on the agar surface. Under a microscope, yeast cells also have a distinctive oval shape.
Endo-cercical swab test m c and s what are these tests?
Microscope, culture and sensitivity test
How does a stool culture work?
A sample of the patient's feces is placed in a special medium where bacteria is then grown. The bacteria that grow in the culture are identified using a microscope and biochemical tests.
Is a closed culture system is used to determine a population growth curve?
Yea, this is the only way the culture will grow.
What was the first culture to determine earth was a sphere?
The ancient Greeks were the first culture to determine that the Earth was a sphere. Philosophers such as Pythagoras and Aristotle provided evidence through observations and reasoning that supported this belief.
What does an autonomous culture mean?
In an autonomous culture, individuals determine for themselves what is right and wrong, moral relativism. The United States describes themselves as an "autonomous culture", one reason why the culture in America is collapsing.
What is the medical term for the sample of the drainage that was grown in the lab to identify the microorganism and determine the best antibiotic?
Culture and sensitivity, sometimes abbreviated C&S, is the process of growing a sample to ID the organism (culture) and determine which antibiotics are active against that pathogen (sensitivity).
What three factors determine who a country trades with?
um....culture tradition and libido
What is the difference between national culture and corporate culture?
corporate culture : The operating environment of a business, including its values, norms, and the behavioral patterns of its employees.corporate culture includes the norms and behaviour which determine how people collaborate
Is there any difference between compound microscope and inverted microscope?
Special type of compound microscope, developed c. 1850, in which the specimen is illuminated from above and observed from below. A prism placed under the specimen reflects the light rays into body-tube. This feature made it possible to observe reactions without visual disturbance from the gases or the effervescence generated by them. so highly used in tissue culture experiments
Concept of business in development of business culture?
The concept of business development will vary depending on the culture. Since businesses operate based on customer demand, the culture will determine what services are demanded.
How many germs are on your toothbrush?
Millions and millions of them can be found on a toothbrush if you had a microscope or Petri dish to culture them. But they are mostly all friendly and will not cause you to get sick.
