katie wants to make ball - and - stick models of the four macromolecules. she has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen in which macromolecule will she use the black, red, and purple balls in a ratio of 1:2:1? carbohydrates lipids nucleic acids proteins

katie wants to make ball - and - stick models of the four macromolecules. she has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen in which macromolecule will she use the black, red, and purple balls in a ratio of 1:2:1? carbohydrates lipids nucleic acids proteins

Answer

Brief Explanations:

Carbohydrates are composed of carbon (black), hydrogen (red), and oxygen (purple) in a 1:2:1 ratio. Lipids have a lower oxygen - to - carbon ratio compared to carbohydrates. Nucleic acids contain elements like phosphorus in addition to carbon, hydrogen, oxygen, and nitrogen. Proteins contain nitrogen in significant amounts and do not have the 1:2:1 C:H:O ratio.

Answer:

A. carbohydrates
