Question

questions: 1. name the 4 main elements that make up 95% of an organism. 2. name the 4 types of bonds carbon can form. 3. what are macromolecules? 4. name the 4 classes of macromolecules. 5. give 2 examples of nucleic acids. 6. what elements make up carbohydrates & lipids (symbols)? 7. name 3 elements your body needs trace amounts of for proper functioning.

Explanation:

1. The four main elements making up 95% of an organism are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). These are fundamental for biological molecules.
2. Carbon can form four types of bonds: single, double, triple, and aromatic bonds (not the ones written in the original attempt which had some inaccuracies like including metallic and hydrogen bonds which are not typical carbon - specific bond types in this context).
3. Macromolecules are large molecules composed of many smaller subunits, often polymers formed by monomers.
4. The four classes of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
5. Two examples of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
6. Carbohydrates and lipids are made up of carbon (C), hydrogen (H), and oxygen (O).
7. Three elements the body needs in trace amounts for proper functioning are iron (Fe), zinc (Zn), and iodine (I).

Answer:

1. Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N)
2. Single, Double, Triple, Aromatic bonds
3. Large molecules composed of many smaller subunits
4. Carbohydrates, Lipids, Proteins, Nucleic acids
5. DNA (Deoxyribonucleic acid), RNA (Ribonucleic acid)
6. C, H, O
7. Iron (Fe), Zinc (Zn), Iodine (I)
