Explanation:

Negative staining in TEM uses an acidic stain that does not penetrate the specimen, creating a dark background around light, intact microbes (including viruses and cellular microbes) for visualization. Shadowing involves coating a specimen with a heavy metal at an angle, which creates a shadow effect ideal for highlighting the delicate, thin structures like bacterial flagella and DNA strands.

Answer:

Negative staining → Used to visualize viruses and cellular microbes
Shadowing → Used to study bacterial flagella and DNA
