Fahrenheit reference points became popular following the work of Anders Celsius and these fixed points were adopted by a committee of the Royal Society led by Henry Cavendish in 1776. Under this system, the Fahrenheit scale is redefined slightly so that the freezing point of water is exactly 32 °F, and the boiling point is exactly 212 °F or 180 degrees higher. It is for this reason that normal human body temperature is approximately 98° (oral temperature) on the revised scale (whereas it was 90° on Fahrenheit's multiplication of Rømer, and 96° on his original scale). The Rankine temperature scale was
Centris pallida of energy. The bacteria, in turn, receive a supply of food which results in a mutualistic relationship. "Centris pallida" are able to withstand very high internal temperatures when compared to other bees. Males regularly have thoracic temperatures of 48 to 49 degrees Celsius (118.4 to 120.2 degrees Fahrenheit). If the thoracic temperature reaches 51 to 52 degrees Celsius (123.8 to 125.6 degrees Fahrenheit), the bee will become paralyzed and die. Most of the cooling occurs when heat radiates off the abdomen. To prevent overheating, "C. pallida" have a very high thoracic conductance (rate of heat transfer from the thorax to
