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:
Fracking can contaminate water supplies if it is not done properly, because the fracking fluid injected into rock to enable gas to be released often contains chemicals. If the borehole is not properly cased to stop leaks, the fracking water can escape into the aquifer
The environment would probably be a grass land or rich forest

Explanation:
Most of the cells in the human body are diploid.
Diploid is <span>a cell or organism that has paired chromosomes, one from each parent. In humans majority of the cells are </span>diploid<span> and have 23 pairs of chromosomes. The exception are the human sex cells (egg and sperm cells). These contain a single set of chromosomes and are known as haploid.</span>
