Allotropes are of same?
Correct answer: D. Elements
- A. Compounds
- B. Molecules
- C. Ions
- D. Elements
Explanation
Option A: Compounds, refer to substances that are formed by the combination of two or more different elements or compounds.Option B: Molecules are formed by the combination of two or more atoms, either of the same or different elements.Option C: Ions are formed by the gain or loss of electrons from atoms or molecules, resulting in a charged species. Allotropes, on the other hand, are different structural forms of the same element and do not involve the gain or loss of electrons to form ions.Option D: Allotropy, is the existence of a chemical element in two or more forms, which may differ in the arrangement of atoms in crystalline solids.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
