<span>The arctic hare lives in the harsh environment of the North American tundra. These hares do not hibernate, but survive the dangerous cold with a number of behavioral and physiological adaptations. They sport thick fur and enjoy a low surface area to volume ratio that conserves body heat, most evident in their shortened ears. These hares sometimes dig shelters in snow and huddle together to share warmth.</span>
<span>The hormone which is being produced under a water-deficit condition which triggers a drought response is known as Abscisic Acid or ABA.
Abscisic acid is termed as a plant hormone. The main functions in the development of plants include
1. Stomatal closure.
2. Control of organ size.
3. Bud dormancy.
It responds to environmental stresses in plants, which include heat stress, freezing tolerance, cold tolerance, soil salinity, and drought.</span>
