Celina has a water sample that’s contaminated with salt and microorganisms. which method should she use to purify the water?

Reverse Osmosis and UV Treatment

Explanation:

Reverse Osmosis, commonly known as RO, process is very effective in removing salt content from water. This process is known as desalination. IN RO, a partially permeable membrane is used to remove unwanted molecules, ions, and large particles. RO will take care of both desalination and purification of water.

Further UV treatment can be done to kill any remaining microorganisms as these microorganisms can not withstand UV radiation.

The answer is reverse osmosis!

Explanation:

I chose this on a test and got it right

porque la cantidad de gases de efecto invernadero alcanzó un nuevo máximo sin precedentes, causando daños muy graves a esta, por eso es importante monitorearla, para controlar el porcentaje de daños que esta causa y poder reducirlo o mantenerlo.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
