The word that best describes the changes in color a chameleon makes in various environments is ADAPTATIONS.

Chameleons are known for their remarkable ability to change color, which serves multiple functions such as camouflage, temperature regulation, and communication. This ability is a form of adaptation, allowing them to blend into their surroundings and avoid predators, as well as to express their mood and attract mates. Adaptations are traits that have evolved over time to enhance the survival and reproductive success of an organism in its environment. In this case, the physiological changes in a chameleon's skin color are adaptations to its environment.

Thus, the correct answer is ADAPTATIONS.
