An $\mathring{A}$ is one-hundredth of a micron.

Vedclass · Answer

(A) The correct answer is $A$. Statement $A$ is false because $1 \mathring{A} = 10^{-10} 	ext{ m}$ and $1 \mu	ext{m} = 10^{-6} 	ext{ m}$. Therefore, $1 \mathring{A} = 10^{-4} \mu	ext{m}$, which is one-ten-thousandth of a micron, not one-hundredth. Statement $B$ is true; electrophoresis is a standard technique for separating proteins based on charge and size. Statement $C$ is false in a technical sense as a compound microscope produces a real, inverted image at the eyepiece, but often the final virtual image is discussed; however, compared to option $A$, $A$ is mathematically incorrect. Wait, checking option $C$: A compound microscope produces a final virtual, inverted image. Thus, both $A$ and $C$ contain inaccuracies, but $A$ is a fundamental unit conversion error. Statement $D$ is true; phase-contrast microscopy is specifically designed to view unstained living specimens.
