Tom’s company has been contracted to excavate uranium ore with minimal ground disruption. what process should his company use?
1)open surface mining
2)in situ leaching
3)hydraulic fracturing
4)deep well excavation

The correct answer is option 2, that is, in situ leaching.

Explanation:

The in-situ recovery also known as in-situ leaching or solution mining is a process of mining, which is generally used to obtain minerals like uranium and copper via boreholes drilled into a deposit. The in-situ leach functions by dissolving the minerals taking place in a solid state artificially. The procedure at the start requires the drilling of holes into the deposit of ore. After that, the leaching solution is inserted into the deposit where it comes in contact with the ore. The solution comprising the ore in the dissolved state is then pumped to the surface and is then processed.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
