Match each stress-related term to its correct definition: Terms: 1. Stress 2. Strain 3. Housing stressor 4. Handling stressor Definitions: A. External demand or force tending to disrupt homeostasis B. Internal physiological or behavioral displacement brought about by an applied force C. Physical environmental condition that challenges an animal's comfort or health D. Human-directed management practice or interaction that requires an animal to adapt

The matches distinguish the general physiological terms from examples of stressors. Stress describes an external challenge, while strain is the internal consequence. Housing and handling are different sources of challenge: housing concerns the physical surroundings, while handling concerns management interactions. Neither example is limited to temperature. **Key takeaway:** Correctly identifying the stressor and the resulting strain clarifies how management conditions can influence animal performance.\n\n**Glossary:**\n- **Homeostasis**: Maintenance of relatively stable internal conditions.\n- **Housing**: The animal’s shelter, space, surfaces, and associated physical conditions.\n- **Management practice**: A human-directed procedure used to care for animals.
