He ability of a stream to erode and transport materials is largely based on its velocity.
The reptile's body temperature rises when the external temperature rises. When the temperature drops, so does his body temperature. If a reptile feels cold because the external temperatures have made his blood cold, he'll lie in the sun to warm up. However, if the external temperature is too high, he scurries under a rock, dives in a pool or finds some kind of shade where he can cool down. Reptiles and other animals with ectothermic systems are vulnerable to extreme changes in temperature because they can't control their temperatures internally. They can control their body temperatures only by moving to an environment with a suitable ambient temperature.
Answer:
Potential Energy and Kinetic Energy
Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. During transpiration water evaporates from the leaves and draws water from the roots.
