It can concentrate its urine, so that minimal volume of water is used to expel excretory products. [...]
Living organisms cope with stressful conditions by any of the following methods: Method # 1. Regulate: Homeostasis is maintained by ensuring constant body temperature and constant osmotic concentration. a. All birds, mammals, a few lower vertebrates and invertebrates have the mechanism of thermoregulation and osmoregulation for maintaining the homeostasis. b. During summer, sweating occurs profusely and the evaporation brings down [...]
