The human core body temperature is normally 37°C no matter what the temperature of the surroundings or the activity level of an individual. To help reduce the body temperature, sweating occurs. Sweat is mostly water with some salt. It is produced by the sweat glands and pours out onto the surface of the skin. How does sweating help to cool and regulate body temperature? The increased salt concentration of the body's cells helps maintain a lower body temperature. B) Water has a high heat of vaporization; the human body can dissipate excess heat by the evaporation of sweat. C) The low specific heat of water allows it to readily evaporate into the atmosphere, quickly cooling your body. D) Water's cohesive properties cause water molecules to stick together requiring the body's thermal energy to evaporate sweat into the air.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
