What is the use of resuspension of supernatant in fresh medium?
LB medium
Why did DNA in Hershey-Chase experiments end up in the supernatant?
It didn't. The DNA ended up in the pellet-like bacteria that was at the bottom of the centrifuge. The protein capsids ended up in the supernatant because they weren't injected into the bacteria cells. The supernatant was separated from the bacteria cells because the bacteria was heavier and fell to the bottom.
The liquid form in decantation called?
Decantation is the process of separating mixtures by removing the liquid and leaving behind the sediment. The liquid portion is called the decant.
Why is best to read test tubes as soon as supernatant is discernible in laboratory experiments?
To prevent it from mixing up again
What happened to the water after filtering?
After filtering muddy water, the mud is left behind as a sludge. If the filter is not frequently cleaned of this sludge, the filtering efficiency is reduced, even to stop altogether.
What does the term supernatant refer to scientifically?
The term supernatant scientifically refers to lying above a precipitate or sediment. Supernatant scientifically also refers to floating on the surface of a liquid.
What is the color of supernatant liquid in decantation?
The color is different for each system; if the approx. pure water is the supernatant, this is colorless.
Supernatant and pellet?
Supernatant is the clear fluid above a precipitate or sediment. Pellet is a small rounded object, ball, or spherical body.
What is the solution that remains after a precipitate has formed?
Supernatant.

Why is it necessary to test for complete precipitation if a supernatant solution is going to be subsequently tested for ions?
The presence of unprecipitated ions in the supernatant may react with subsequent reagents added and obscure the results of tests.
When centrifuging a mixture the lighter material in the solution on top is called?
the supernatant
What is the difference between supernatant and filtrate?
supernatant - liquid above and solid in the bottom, the supernatant is the liquid above that is going to be poured off (to separate the solid and the liquid) filtrate - it is also the liquid part but the solid and liquid is separated differently, for example coffee the filter paper holds on to residue (solid) and the liquid part (filtrate) passes I think that is the difference.

What is the clear liquid above the sediment called?
The fluid above the sediment after centrifugation is called the supernatant.
