Which processes contribute to the formation of chemical sedimentary rocks?

hurry i’m timed ‼️‼️

organisms decay in a solution.

minerals dissolve and crystalize.

rock fragments squeeze together.

the remains of plants and animals.

Option B, Minerals dissolve and crystalize.

Explanation:

Minerals in the ground seeps down the ground through the precipitating water.

Addition of water causes their crystallization. The precipitated minerals reaches the pore spaces beneath the ground and form mineral crust on the sedimentary grains.

This causes cementation of the sediments due to the temperature and pressure beneath the ground. After the cementation, a sedimentary rock is formed.

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.
