multiple choice question
how does temperature affect the color pigment in the fur of siamese cats?
the fur on the cats tail, feet, ears, and nose is usually lighter than the fur on the rest of the body.
in cooler regions of the body, the fur is darker. in warmer regions the fur is lighter.
in warmer regions of the body, the fur is darker. in cooler regions the fur is lighter.
the fur on the cats tail, feet, ears, and nose is usually that same color as the fur on the rest of the body.

Explanation:

Siamese cats have a temperature-sensitive enzyme that produces dark pigment. Colder body regions (like extremities) keep this enzyme active, making fur darker, while warmer core regions inactivate the enzyme, leading to lighter fur.

Answer:

B. In cooler regions of the body, the fur is darker. In warmer regions the fur is lighter.
