For much of the last quarter century, the leading theory of the driving force behind tectonic plate motions envisaged large scale convection currents in the upper mantle, which can be transmitted through the asthenosphere. So letter C. is the Answer.
Answer:
The answer to the question is C ectothermy
Explanation:
The answer to the question is C ectothermy
The traits which all organisms with no internal thermoregulation have are called an Ectothermy. Ectothermy is an organism in which the inner behavioral heat sources are significant in the regulation of body temperature. This organism depends on their ecological heats source, which allows them to work at an efficient rate. Some of this organism stays in an area where temperatures are nearly constant.
