- During exercise in a hot and humid environment, the inability of the body to lose excess heat through evaporation increases: Group of answer choices Core temperature Risk of heat injury or heat illness Risk of dehydration Sweat rate All of the aboveTemperature and wind combine to cause heat loss. Hypothermia occurs when the body temperature falls more than 4 degrees F below normal. Death can occur if hypothermia persists for over 3 hours. According to the chart, in which of the following temperature and wind combinations would the body temperature be the lowest and a person most at risk for developing hypothermia?Heat exchange with the environment depends on the surface area-to-volume ratio of the body. Assuming that the body shape of an animal is at least somewhat spherical, a considerable decrease in body size would _______ the surface area-to-volume ratio, and the ability to exchange heat with the environment would _______. A. increase; increase B. increase; stay about the same C. increase; decrease D. decrease; increase E. decrease; stay about the same
