Peripheral chemoreceptors sensitive to changes in plasma carbon dioxide and oxygen levels are located

Peripheral Chemoreceptors that are sensitive to changes in plasma carbon dioxide and oxygen levels are located in the aortic arch and carotid arteries. In which, Carotid are known to be the main oxygen sensors. The artery will drop before the oxygen level develops into a major stimulus in order to upsurge ventilation.

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.
