Why is aseptic technique necessary for successful cultivation of pure cultures in the laboratory?
Short answer is Koch's postulates.
Long answer you can't ascribe any scientific data you may gather to a bunch of bacteria on a plate or in a culture, as you won't know which of the bacteria gave you the result you observed.
So if you are trying to figure out which bacteria causes a disease, inoculating a mix of bacteria won't tell you which one causes the disease. Isolating each one using aseptic technique and then inoculating individually and finding the disease in one animal will tell you which bacteria caused to disease.
What else can I help you with?
If a laboratory technique that is utilized to test cell responses is?
If a laboratory technique used to test cell responses is not yielding the expected results, it may be due to variations in experimental conditions, cell population heterogeneity, or issues with the technique itself. Troubleshooting could involve optimizing experimental parameters, verifying the quality of reagents, or validating the technique with positive controls. Collaborating with colleagues or seeking advice from experts in the field may also help in troubleshooting the technique.
What type of technique is referred to as clamping?
The patch clamp technique is a laboratory technique in electrophysiology that allows the study of single or multiple ion channels in cells. The technique can be applied to a wide variety of cells, but is especially useful in the study of excitable cells such as neurons, cardiomyocytes, muscle fibers and pancreatic beta cells.
The laboratory technique is used to separate the different pigments in a green leaf?
Chromatography is the laboratory technique used to separate the different pigments in a green leaf. The leaf pigments are separated based on their solubility in the solvent used. By analyzing the bands of separated pigments, researchers can identify and quantify the different pigments present in a leaf.
What is laboratory technique in which the body radioactively labeled a substance is mixed with a blood specimen?
The laboratory technique you are referring to is known as radioimmunoassay (RIA). In RIA, a radioactive substance is used to label a specific molecule or antigen, and when this labeled molecule is mixed with a blood specimen containing the corresponding antibody, the level of radioactivity can be used to quantify the amount of antigen present in the blood sample.
What is the technique in which cells are broken into pieces and the different cell parts are separated?
The cell fractionation

The technique of seeing yourself as successful is called?
affirmation
How poor laboratory technique?
explain why labortory safety is every one's concern. explain is a compare and contrast format, how poor labortory technique can lead to inaccurate results. why can we not just dump chemicals down the sink after we complete our laboratory experiment?
What is the purpose and technique of vortexing in a laboratory setting?
The purpose of vortexing in a laboratory setting is to mix or agitate liquid samples quickly and efficiently. This technique involves placing the sample in a vortex mixer, which creates a swirling motion to ensure thorough mixing of the components.
If a laboratory technique that is utilized to test cell responses is?
If a laboratory technique used to test cell responses is not yielding the expected results, it may be due to variations in experimental conditions, cell population heterogeneity, or issues with the technique itself. Troubleshooting could involve optimizing experimental parameters, verifying the quality of reagents, or validating the technique with positive controls. Collaborating with colleagues or seeking advice from experts in the field may also help in troubleshooting the technique.
What is sterile technique what dose this involve when should this be used?
Sterile technique is a procedure that includes the medical and the laboratory techniques like with cultures. Sterile technique includes techniques such as flame sterilization and it should be used in hospital operating theatres.
Is a PET a laboratory procedure?
PET (Positron Emission Tomography) is a very modern and expensive medical imaging technique.
A common technique used in the laboratory is using the deductive approach to the scientific method what is the purpose of this approach?
prove that the hypothesis is wrong
Whose sloppy laboratory technique allowed a mold of the genus Penicillium to land on an agar dish of bacteria?
Alexander Fleming.
What type of technique is referred to as clamping?

The technique can be applied to a wide variety of cells, but is especially useful in the study of excitable cells such as neurons, cardiomyocytes, muscle fibers and pancreatic beta cells.
What is crowded plate technique?
The crowded plate technique is a method used in scientific research where a large number of samples are tested simultaneously on a single plate. This technique helps to conserve resources, reduce waste, and improve efficiency in laboratory experiments.
What technique is most effective in destroying spores in a medical laboratory?
Autoclaving is the most effective technique for destroying spores in a medical laboratory. This method uses high pressure and steam to sterilize equipment and kill spores, ensuring that they are completely eradicated. It is a standard practice in healthcare settings to prevent the spread of infectious agents.
