○ support structure
○ energy storage
○ energy use
○ genetic material

1. choose the best answer.

dna is made out of what monomer?
○ monosaccharide
○ nucleotide
○ fatty acid
○ amino acid

1. choose the best answer.

what shape does dna have?
○ spherical

Explanation:

Question 1

DNA (deoxyribonucleic acid) is known to carry the genetic information in living organisms. Support structure is done by components like cell walls or cytoskeleton, energy storage by molecules like glycogen or fat, and energy use involves processes like cellular respiration. So the correct option is related to genetic material.

DNA is a nucleic acid, and the monomer (building block) of nucleic acids is nucleotides. Monosaccharides are monomers of carbohydrates, fatty acids are part of lipids, and amino acids are monomers of proteins. So the correct monomer for DNA is nucleotide.

Answer:

genetic material
