3. Which statement describes starches, fats, proteins, and nucleic acids?
A) They are used to store genetic information.
B) They are complex molecules made from smaller
molecules.
C) They are used to assemble larger inorganic
materials.
D) They are simple molecules used as energy
sources.

B

Explanation: Because if u Look at Protein Carbohydrates Nucleic acid and fatty acid actually they are polymers made up of small units called monomers.Option C is incorrect because these are organic molecules containing carbon so we cannot say that it will form an inorganic structures and the other option says about genetic information so genetic information is only determined by Nucleic acids not fatty acid, Protein or Carbohydrates and last option D is incorrect because nuclei acid didn't provide energy.

i think the answer is

mass

not sure if this is what you'r looking for eubacteria and archaebacteria
