Which term describes the stage during which some bacteria coat themselves with a wax-like shell and can resist killing?

• A. Active stage
• B. Inactive or spore forming stage
• C. Toxins
• D. Pus

Answer: (B)

Bacteria can switch into a dormant, highly resistant form called an endospore when conditions are unfavorable. In this inactive or spore-forming stage, they encase their genetic material and essential components inside a tough, wax-like spore coat that helps them survive heat, chemicals, and drying. When conditions improve, the spore can germinate back into an active, growing cell. That’s why this term best describes the stage described. The other options refer to an active, metabolically working state or to substances related to infection, not a dormant, protective life stage.
