Siberian tigers originated in the far northern continent of Asia. The climate is extremely cold, since much of the land is within the Artic Circle. They were forced south over time and now reside in Southeast Asia, such as India, Thailand and Cambodia. They still have thick fur. Unlike other cats, wild or domestic, they soak in water to cool their bodies.
This adaptation is an example of a variation in
A. genetics
B. behavior
C. structure
D. physiology
behavior
behavior
structure
The adaptation of Siberian tigers soaking in water to cool their bodies is an example of a variation in behavior, which is option B.
To arrive at this answer, we can understand the different options and eliminate those that are not relevant.
A. Genetics refers to the inherited traits passed down from one generation to another. While the thick fur of Siberian tigers can be attributed to genetic factors, the behavior of soaking in water is not directly related to genetics.
C. Structure refers to the physical features and characteristics of an organism. While the thick fur of Siberian tigers can be considered a structural adaptation for surviving in cold climates, soaking in water is not related to their physical structure.
D. Physiology refers to the functions and processes of living organisms. Here, soaking in water is a physiological adaptation as it helps them regulate their body temperature and cool down in hot environments. However, as a pre-defined answer, the option B (behavior) would be more appropriate for the given scenario because it specifically refers to actions and responses of an organism.
Thus, the correct answer is B. behavior.
