Acompany has a volume of contaminated water that needs to be separated through evaporation. what would allow the mixture to be separated in the shortest time?

placing the water in a single deep pool in a shady spot
placing the water in a single deep pool in a sunny spot
placing the water in several shallow pools in a shady spot
placing the water in several shallow pools in a sunny spot

placing the water in several shallow pools in a sunny spot

Explanation: Evaporation is a surface phenomenon which lets the higher energy molecules leave the surface of liquid in the form of vapors.

The molecules absorb energy from the surroundings and thus placing the water in sunny spot would let the molecules have  more energy and they can easily escape into the atmosphere and thus contaminants will be left and water vapors can be condensed back to get it in liquid form.

Evaporation is directly proportional to the surface area of the liquid and thus several shallow pools will lead to more evaporation.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
