Question

All biomolecules have the following traits except? a, covalent bonds b, hydrogen elements c, a carbon backbone d, nitrogen elements

Answer 1

All biomolecules have the following traits except **b, hydrogen elements**.

While biomolecules do contain hydrogen atoms, they are not exclusively characterized by them as a defining trait. The other options (covalent bonds, a carbon backbone, and nitrogen elements) represent structural features and components that are more fundamental to the definition of biomolecules such as carbohydrates, proteins, lipids, and nucleic acids.
