What term describes a biological agent or condition that constitutes a hazard to humans?

• A. Bleeding
• B. Biohazard
• C. Blindness
• D. Bone loss

Answer: (B)

The idea here is recognizing the term that labels a danger to people when it comes from biology. A biohazard is any biological material or situation that could cause illness, infection, or other harm to humans. This includes things like infectious agents (bacteria, viruses, fungi), contaminated waste, or body fluids that carry pathogens. In health care and lab settings, recognizing a biohazard prompts precautions such as proper PPE, containment, and safe disposal to protect workers and patients.

The other options describe conditions or symptoms rather than a category of hazard. Bleeding is a symptom or consequence, blindness is a condition, and bone loss is an outcome; none of them function as the general label for a risk from biological materials.
