Chemical reactions can create more complex products. What evidence best explains this phenomenon? WILL MARK BRAINLIEST FOR CORRECT ANSWER (100 points)
Water molecules combine to form complex macromolecules that the body needs.
The molecular structure of complex macromolecules show that a chemical reaction has occurred.
Larger macromolecules breakdown into smaller macromolecules and combine during the reaction.
The basic need for oxygen makes the element essential to create macromolecules.
