Briana is studying a model of the light-dependent reactions of photosynthesis. the diagram shows a part of this model. a ray of light strikes photosystem ii. a chemical equation shows that 2 water molecules (h2o) break apart to release 4 hydrogen ions, an oxygen molecule, and 4 electrons. briana notices the electrons that the water molecules release. she asks, "will the electrons build up in the chloroplast? " which addition to the diagram would be most useful for answering briana's question? a. a wavy arrow that shows photosystem i b. an equation for the chemical reaction that forms water from hydrogen ions, electrons, and oxygen molecules c. an arrow that shows the electrons moving through electron carriers, and received by nadp+ d. an equation for the chemical reaction that forms hydrogen gas from hydrogen ions and electrons

it should be briana that has it to me

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

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.
