How can rainfall affect the mineral content of ocean water?

The rainfall increases the mineral content of ocean water.

Explanation:

The minerals in the oceanic water are added by the rainfall through surface runoff. It is a phenomena in which the large volume free flowing water flows over the surface of the soil. This water is not absorbed by the soil instead it takes away along with it all surface materials like chemical fertilizers, soil, sediments, inorganic and organic minerals and deposit them to the water body (ocean, river or others).

Thus this can be said that rainfall increases the mineral content of the ocean water.

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.
