Phase-contrast microscopy is especially useful for detecting bacterial structures like endospores and inclusions because these structures:

are translucent (permit light to pass through them)

Explanation:

Phase-contrast microscopy is especially useful for detecting bacterial structures like endospores and inclusions because these structures are translucent.

Objects viewed under a phase-constrast microscope appear with a opposite colour, and do not require stain or dye to be viewed

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
