what is not a trait of biomolecules?
hydrogen elements.
nitrogen elements.
covalent bonds.
a carbon backbone.
To determine which option is not a trait of biomolecules, we need to understand what each of these options represents.
1. Hydrogen elements: Hydrogen is an essential element that is present in many biomolecules, such as carbohydrates, lipids, and nucleic acids. Therefore, hydrogen elements can be considered as a trait of biomolecules.
2. Nitrogen elements: Nitrogen is another important element found in biomolecules, particularly in proteins and nucleic acids. Therefore, nitrogen elements are also a trait of biomolecules.
3. Covalent bonds: Covalent bonds are the primary type of chemical bonds formed between atoms in biomolecules. They are formed by the sharing of electrons between atoms, providing stability to biomolecules. So, covalent bonds are indeed a trait of biomolecules.
4. A carbon backbone: A carbon backbone refers to a chain of carbon atoms that forms the main structural framework of organic molecules. Carbon is a versatile element that forms the basis of biomolecules such as carbohydrates, lipids, proteins, and nucleic acids. Therefore, a carbon backbone is typically present in biomolecules.
Based on the above explanations, we can see that option "hydrogen elements," "nitrogen elements," and "covalent bonds" are all traits of biomolecules. Therefore, the option that is not a trait of biomolecules is "a carbon backbone."
