An animal that migrates annually to warmer climates is exhibiting a:

• A. Structural adaptation
• B. Behavioral adaptation
• C. Genetic mutation
• D. Symbiotic relationship

Answer: (B)

Migrating annually to warmer climates shows a behavioral adaptation—the animal changes its behavior to cope with seasonal changes and survive by moving to areas with better resources. This is about actions taken in response to the environment, not a physical change to the body. Structural adaptations would be physical traits like thicker fur or longer legs. A genetic mutation would be a change in DNA sequence, not an intentional behavior. A symbiotic relationship involves interactions with another species, not the animal moving to a different climate.
