One of the four regions in a coordinate plate separated by an x-axis and a y-axis?
A quadrant.
What is the function of a treadle?
A treadle is a foot operated plate, which when pressed, causes a rotary movement for a machine.The plate is connected, usually via a rod, to a crank. Pushing on the treadle in a careful, repeated manner, will move the crank and cause rotary motion in the machine.
The diameter of a round dinne plate is 10 inches what is the area of the plate?
25pi
Where do the foul lines intersect with home plate?
the foul lines come directly to the point on the back of home plate. that is why a ball off the plate is a fair ball
What is the weight of 4 mm chequered plate?
4mm chequered plate unit weight
What is the technique you used in purify the bacterial culture on a plate?
I used streak plate technique to purify the bacterial culture on a plate. This involved streaking the culture onto the agar surface in a specific pattern to isolate individual colonies by dilution. Subsequent incubation allowed the colonies to grow separately, enabling the selection of pure cultures for further study.
Why can't we talk when streaking LB Agar plates?
Because when u talk while streaking some bacteria could come from your mouth and get on the plate from spit or somehow. There fore talking is not a very good aseptic technique.
Advantages of pour plate method over other methods of bacterial colony?
The purpose of the spread-plate technique is to grow and isolate colonies of bacteria. A sample of bacteria is transferred to the agar plate, an environment that provides nourishment for the bacteria to grow. The bacteria sample is applied to the agar plate which a special streaking technique that dilutes the amount of bacteria in each section of the agar plate continuously. This is because if you just swabbed the bacteria onto the plate with no special technique the colonies would grow very densely together and be difficult to study. The streaking technique gradually dilutes the amount of bacteria in each 'quadrant' of the plate, so the last quadrant should have small, isolated colonies that can be easily studied. The spread plate technique is also used for the eneumeration of aerobic microorganisms from the given sample. This can be done by serial diluting the samples, placing 0.1ml of the diluted sample in the middle of an agar plate and spreading the sample over the surface with a help of an L-rod. After the incubation rhe colonies can be counted.
What explanation could be given for the failure of obtaining isolated coloni es on a streak plate?
Failure to obtain isolated colonies on a streak plate could be due to overcrowding on the plate, improper streaking technique, or contamination of the plate from the environment or the inoculation source. It is important to streak the plate in a way that allows for sufficient separation of individual colonies to form.
Why must have 4 part in streaking technique?
The streaking technique is used to isolate bacterial colonies on an agar plate. Four quadrants are streaked to dilute the bacteria as they are spread across the plate, helping to create isolated colonies for further analysis and identification. This method ensures that each colony originates from a single bacterium, aiding in the identification of individual species.
What is the name of the streak when you apply specimen to agar plate?
The process of applying a specimen to an agar plate to grow colonies is known as streaking. This technique involves using an inoculating loop to spread the specimen across the surface of the agar in a pattern that promotes the isolation of individual colonies for further study.
The white powder left behind by a mineral on a white tile?
When you rub a mineral on a tile it is called streaking a mineral. The line that is left is called the streak, and the tile itself is called a streaking plate.
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.
Why does the streaking method you used to inoculate you plates result in isolated colonies?
Streaking involves diluting the sample across the agar surface, which helps to separate individual bacterial cells and prevent them from overlapping. By streaking in a pattern, single cells are left behind at the start of the streak, leading to the formation of isolated colonies as they grow and multiply.
What is strip plate technique?
The strip plate technique is a method used in microbiology to determine the minimum inhibitory concentration (MIC) of an antimicrobial agent against a specific bacterium. It involves placing paper strips containing various concentrations of the antibiotic onto an agar plate inoculated with the bacteria, allowing the antibiotic to diffuse into the agar and create a gradient of concentrations. The lowest concentration of the antibiotic that prevents visible bacterial growth is considered the MIC.
How do you isolate the bacteria from mixed culture which contains Fungus?
One method to isolate bacteria from a mixed culture containing fungus is by streaking the culture onto agar plates using a technique called streak plating. By streaking the mixed culture several times in decreasing concentrations on different sections of the plate, individual bacterial colonies can be isolated apart from the fungus. Dilution and selective media can also be used to encourage the growth of bacteria while inhibiting fungal growth.
What is the differences between a streak plate technique and a serial dilution technique?
A streak plate technique is used to isolate individual bacterial colonies on a solid agar plate to obtain pure cultures, while a serial dilution technique is used to dilute a bacterial sample in a series of steps to obtain a range of concentrations for further analysis. Streak plate technique is qualitative, focusing on colony isolation, while serial dilution technique is quantitative, focusing on estimating bacterial concentration.
