For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. Ways of【C1】______ the difference have become more accurate and meaningful over time, but popular terminology still reflects the old【C2】______ into "warm blooded" and "cold blooded" species: warm blooded included mammals and birds,【C3】______ all other creatures were considered cold blooded. As more species were studied, it became evident that this classification was 【C4】______. A fence lizard usually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a【C5】______ body temperature and those whose body temperature varies with their environment. But this classification also【C6】______ inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates that live in the【C7】______ of the ocean never experience a change in the chill of the deep water, and their body temperatures remain constant. The current distinction is between animals whose body temperature is regulated chiefly by internal metabolic processes and those whose temperature is regulated by the【C8】______. The latter do so mainly by moving to favorable sites or by changing their exposure to【C9】______ sources of heat. Mammals and birds also regulate their temperature by choosing favorable environments, but primarily they regulate their temperature by【C10】______ a variety of internal adjustments. [br] 【C3】
