Three adaptations by pronghorn allow them to eat sagebrush in winter. First, pronghorn are opportunistic herbivores. As such these animals are able to…

Each receptor is triggered by a specific stimulus. Thermoreceptors detect temperature changes and send electrical pulses through sensory nerves to…
