Iron is a type of metal. therefore, the iron has a sparkling surface nature. however iron is easy to rusty. why?

Explanation:

When iron gets in contact with oxygen (or water, which also contains oxygen) it starts giving electrons to the oxygen atoms, in a process called oxidisation, and when that occurs, iron oxide () is made.

Note: iron oxide is what we call rust. And, iron is so easy to rust because it usually isn't mixed with any other protective metals or covered in protective films.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

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.
