Elements are pure substances that make up all matter. gold, aluminum, iron, and lead are some examples of these pure substances. what is the basic building block of all pure substances that make up matter in the world? a) atoms b) cells eliminate c) compounds d) metals

The right option is; A) atoms

Atoms are the basic building blocks of all pure substances that make up matter in the world. Atoms can combine together to form molecules, which can also form objects. Atoms are made up of tiny types of particles (protons, neutrons, and electrons) . Protons have a positive electrical charge, electrons have a negative electrical charge, while neutrons are neutral (without any electrical charge).

answer; i believe that the correct answer is (lung);

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.
