Which term names a microscope's ability to distinguish two adjacent structures as separate?

1. Magnification and resolving power are the two parameters that matter in microscopy. 2. Magnification is the process of enlarging an object in appearance. 3. Resolving power is the ability to tell two adjacent structures apart, and the higher it is, the better the clarity and detail. 4. Enlarging an image without separating adjacent structures gives a bigger but blurred picture, so magnification is the wrong label. 5. The ability to separate two adjacent structures is resolving power. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 4 "Cell Structure", section 4.1 Studying Cells_
