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:

Explanation:
<em>Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.</em>
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
<u>It thus showed that new life does not arise spontaneously but rather through development and reproduction.</u>
