Peter was in a coma for several days after falling from a ladder. the doctor indicated that he suffered damage to an area of his brain. which area of peter's brain was most likely damaged?

The area of the brain which has a damage is the reticular[L1]  formation.  You can find the reticular formation in the brainstem, it is a set of interconnected nuclei. The reticular formation is not anatomically well defined because it includes neurons located in diverse parts of the brain. In medulla oblongata in the lower part to the upper part of midbrain it stretches in the core of the brainstem, neurons of the reticular formation made up of complex set of networks.

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.
