Because it need to preserve for DNA expert to use. Just like all the living things if an animals is died in snow, snow are used to preserve them. Same as DNA
It actually makes the dehydration of DNA molecules which makes the DNA precipitate.
The ice cold ethanol precipitates the dissolved DNA in the solution. The precipitated DNA is centrifuged and the pellet below is collected and dried for further use.
Because you wanted to anyway. The ethanol just loosened your inhibitions.
precipitation
Precipitation in weather terms (rain, snow, etc.) is a physical process. Precipitation in chemical terms (e.g. lead iodide falling out of solution) is a chemical change.
Brazil is the leader using as high as 25% Ethanol+Gasoline mixture... very closely followed by USA.. other countries like China, Australia, Sweden, Colombia use Ethanol as fuel.
"Precipitation" refers to "falling out". In a chemical reaction, precipitation refers to a process where liquid or dissolved chemicals react to form another compound which is insoluble, and solid "flakes" of the compound "fall out" of the solution and settle to the bottom. In meteorology, "precipitation" refers to water "falling out" of the clouds as rain or snow.
A Doppler radar is used for "seeing" precipitation and how heavy it is. It can also see the direction the precipitation is moving and the winds inside the rain clouds or thunderstorms and can pick out the rotation which can lead to a tornado.
No.
Precipitation from the solution may lead to complications such as pulmonary microcapillary occlusion and blockage of blood flow.
precipitation
lead sulfate can be precipitated, but plain lead is already solid, and gets that way at room temperature.
Precipitation in weather terms (rain, snow, etc.) is a physical process. Precipitation in chemical terms (e.g. lead iodide falling out of solution) is a chemical change.
The type of front which will lead to turbulent air and precipitation is a cold front. When warm cold air collides with warm air, it will generally produce severe weather.

It is possible, especially if there was a fire where these elements where present.
Yes. PbCl2 (s)
Ethanol can cause damage to engine parts. It can also lead to damage with seals that protect your motor because it eats away at rubber.
Ethanol is basically bad for you. A little is ok, but you have to be sencible. Too much ethanol can lead to high riscs of trauma, and is stored in the liver and cause seizures. Way to much and you can die or kill someone else through your fault of drinking.
