determine whether these animal are poikilothermic or homoeothermi c, endothermic or ectothermic, and whether they are cold adapted or warm adapted. Assume that you are unable to determine their habitat climate and have to relay solely on their anatomy and physiology to make that determination. Please answer 4 of the following questions 40 pts each Please indicate in the blue book the number of the question you are answering. 1. Mammals adapted to cold and hot environment share a few physiological adaptations such counter current mechanisms, changes in metabolic rate, adjustments in conductance among others. Please give as many specific examples as you can--compare how these physiological mechanisms work in similar or different ways in heat and in the cold adapted animals. 2. Please describe all the ways that desert adapted animals conserve water. Make sure to include the specialized anatomical adaptations as well as the physiological mechanisms. Make sure to use specific examples 3. Please describe the environmental conditions of deserts and using prominent examples and oths plase discues in detail all the
