This composition does not vary. - Mixtures, on the other hand, are composed of two or more substances physically combined. The components of a mixture can be present in varying proportions, leading to a variable composition. - Option A correctly distinguishes between pure substances and mixtures based on the fixed composition of pure substances and the variable composition of mixtures.

5. What is the 3D structure of a protein called?

Correct answer: A

Therefore, the 3D structure of a protein is called the tertiary structure because it represents the overall folding of the protein into a specific shape.
