Which three of the following are examples of adaptions for an animal that lives in a snowbound region

Dense hair all over the body to protect from cold, and a thick layer of fat to insulate body.Those are the main adaptations, an animal of the same species but in another environment would not accumulate reserves of fat, nor its hair would be so thick, not to mention that some species change the color of their fur to camouflage themselves between snow and nature.

Used to water and cool climates, probably not thick coated or fluffy. they most likely have thin coats and have to survive to find food. sorry if this wasn't the answer you were looking for..: )
