Document Summary
Topic 4 thermoregulation, temperature has a major influence on everything, because reaction rate depend on it, broad range of temperatures that animals can tolerate, 1 50 degrees (freezing and protein denaturation), lethal temperatures, antarctic fish, narrow temperature range because its likely to see it in its environment, eurythermic broad temperature tolerance, stenothermic small tempreture tolerance. Follows that of the enviroment: homeotherm constant body tmep, endothermic type 1 can maintain body temps despite changes in environment type 2: called homeothermic because they envrioment thye are in remains the same all the time and they asismiliate to that, animal generates metabolic heat to maintain temperature, mammals and birds, exothermic animals, metabolic heat production doesn"t contribute in maintaining body temperature, heterotherms , animals that don"t fit the other categories, they can be temporal heterotherms in which temp fluctuate over time, or regional heterothem in which (different parts of body have different temperature, temporal hibernators, maintained body temperature except at certain times of year.
