Mira analyzed oxygen and carbon dioxide in inhaled and exhaled air. she found that the percentages of both gases were different in each. what other gas would most likely also have different amounts in inhaled and exhaled air?

The composition of exhaled air or breathed out air is very different from the composition of inhaled air or breathed in air in terms of percentage of oxygen and percentage of carbon dioxide. Besides these two gases, the amount of water vapor is also different in inhaled and exhaled air. Inhaled air has contains very little water vapor whereas exhaled air is saturated with water vapor.    

answer; a muscle cell, another neuron and a of the above

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.
