Multiple Choice

The Griffey stain is more intense than the PAS stain.

Explanation:
The main idea here is that stain intensity depends on how strongly the dye binds to and reacts with the target components in the tissue under the same conditions. If one stain is described as more intense than another, it means it deposits more color—producing a darker, more saturated result for the same structures. The Griffey stain is formulated to give a stronger color signal for its targets than PAS does for carbohydrates, often because its dye molecules have a higher affinity, or because the staining chemistry (mordants, chromogens, or reaction steps) yields more chromogen per binding event. So, under identical sectioning and staining conditions, Griffey staining will appear darker than PAS. Remember that exact intensity can vary with tissue type, fixation, and protocol, but the described comparison reflects a higher color yield with Griffey in typical use.
