Respiratory is produced by inadequate excretion of CO2 with inadequate ventilation, resulting in elevated plasma CO2 and increased levels of carbonic acid.

acidosis

Explanation:

Respiratory acidosis is caused due to hypoventilation because of which gas exchange process is hindered. As a result CO2 produced in body is not excreted adequately and it starts to accumulate. Its concentration in plasma increases and it combines with water molecules in plasma to form carbonic acid. Carbonic acid drops the pH of the blood and thus acidic environment is created. Since this event is a product of faulty respiratory mechanism, it is called respiratory acidosis.

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.
