Which matter holds its own shape?
solid
Through which medium will sound move fastest?
Contrary to light, sound travels faster through a denser medium than a less-dense medium, meaning it will travel much faster in a solid than a liquid, and faster in a liquid than a solid. This is also why the infamous "If you scream in space, nobody can hear you." holds (some) truth: There isn't enough particles for sounds waves to bounce off of, so it dissipates.
Do electromagnetic waves have to pass through a solid medium?
no
How does the wavelenth changes when light travel from ane optical medium to another optical medium?
Diamond (solid)
Sound travels worst through what medium?
a solid because particles of a solid is not as put together.
Which culture medium preparation is most commonly utilized in isolation of pure culture?
Solid media is used for the isolation of bacteria as pure culture. 'Agar' is most commonly used to prepare solid media.
What is the difference between liquid and solid medium?
In wave motion, the media are said to be liquid and solid according to the states of media themselves, that is, if a medium is in solid state then the medium is said to be solid medium and if the medium is in liquid state, then the medium is said to be liquid medium.
What are advantages of a solid?
The culture on solid media (agar) surface aids microbiologist in identifying microorganism because individual species often from colonies of characteristic size and appearance. When mixed population has been plated properly, it sometimes is possible to identify the desired colony based on its overall appearance and use it to obtain a pure culture. Whereas in liquid broth we get mixed culture and can not identify the seprate colony of any microbial species in that mixed culture.
What is the value of petri plates in microbiology?
It gives microbiologists a way to grow bacteria on a solid medium. This is important if you want to be able to obtain a pure culture, without a solid medium to grow bacteria it would be nearly impossible. On a solid media a single colony can be isolated and used to innoculate a further plate or broth culture. All the bacteria present in a colony should be decendents of a single organism and so be genetically identical. To obtain a pure culture in liquid media, you would have to do numerous serial dilutions which is very labor intensive compared to streaking a solid medium. Even after many serial dilutions there would be no way to ensure a pure culture.
What is the function of media agar?
Agar, which is a polysaccharide polymer, is a solidifying agent for culture medium. It also provides a solid surface for bacterial growth.
What is the role of the agar ingredient in culture medium?
Agar is defined as a gelatinous substance obtained from various kinds of red seaweed and used in biological culture media. It is the culture medium.
What is L-15 cell culture medium?
It is just a type of a culture medium. The "L" there stands for Lebowitz, presumably the last name of the first person who came up with that culture medium.
Why is a solid medium used to purify microorganisms?
Solid medium is used to purify microorganisms so that the microorganism can develop pure colonies quickly. The most commonly used solid medium is agar.
Is a solid a medium?
large.
Is a medium a a solid?
large.
What is speed of sound through a solid medium?
It depends on the medium.
What factor can cause cells to divide in a culture medium?
Protein signals cause cells to divide in a culture medium.
