The four macromolecules essential for life are carbohydrates, lipids, proteins, and nucleic acids. Give an example of each, mention the building blocks(elements) involved, and explain why each is important for life. Your

where is the option.let me know

the answer is; comparing the frequency of collisions with and without the device

it would be heredity
