Which specialized cells are responsible for transmitting messages throughout the body?
neurons
epithelial cells
blood cells
muscle cells

well by process of elimination we can get are answer.

1 muscle cells, what is there function locomotion of your skeletal system and in turn your body.

2 blood cells, can clot blood due to platelets within/making up blood. Plasma carries nutrients excluding oxygen to cells. Red blood cells carry that good old Oxygen necessary for ATP production via the electron transport chain. (Don’t be confused by this ATP can be made in other process like the Krebs cycle, glycolysis, ETC)  Finally white blood cells include lymphocytes, granulocytes, monocytes, and macrophages.  

3 epithelial cells, epithelial cells line the outside of your body and certain things inside your body there main function is pathogen and or virus protection.

So the only possible answer is nerve cells or neurons.

THE ANSWER IS A

Explanation:

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.
