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.
A) a temperature is regulated by the body: so, not.
b) - rather not, most likely cholesterol level would be low
c) this is rather intedependent - a person can be active even without a fat diet.
d) I think this is the best answer. Metabolism is the exchange of energy in food into the energy that people use.
Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
Global warming affects the spread of animals because different areas will become suitable for different species, so they spread out. This can cause diseases to spread, as the animals may bring them with them. This can also happen in the opposite direction, where the climate change causes less habitats to be suitable for animals, so they become more sparse
