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.

I don't really understand what the question is, but I'm pretty sure you're asking for which molecules that will be needed; Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus

Explanation:

-Carbohydrate consists mainly of Carbon, Hydrogen, Oxygen, simple sugars have the basic formula of (CH2O)n. Some modification can be made to the sugar, but the main formula consists only with Carbon, Hydrogen, Oxygen.

-Proteins consists mainly of Carbon, Hydrogen, Oxygen, and Nitrogen for the amide groups. Some amino acid will need Sulfur for it's R Group.

-Fats consists mainly of Carbon, Hydrogen, and Oxygen just like Glucose.

-Nucleic Acids consists mainly of Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus for the backbone of the Nucleic Acid. Nitrogen will be needed for the Nitrogenous Base.

I hope this is the answer you're looking for!

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
