How does the composition of a water molecule affect it's charge

A molecule of water comprises two hydrogen atoms associated with an oxygen atom, that is, the formula of water is H2O. As there is a high difference in the electronegativity of both oxygen and hydrogen, therefore, there will be an unequal distribution of charge on a molecule of water as hydrogen will exhibit a positive charge, while oxygen will possess a negative charge. This will also make the molecule of water polar in characteristic.

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.
