regulation,genetic difference.
2.The better the thermal conductivity of medium ,the less the fluctuation of

temperature in different layer of the profile,why?

3、举例说明温度的变化和水分密切相关。

Answers：

1、Organisms live in an environment of stresses, which might be harmful. So

they use kinds of strategies to live on. Some may escape from the bad

conditions but others become strong enough to overcome the harsh

environment, and that is tolerance. This can maintain life cycles from

generation to generation. That's we called homeostasis. And this will always

lead to genetic variation after a long enough time. All this could be treated as <
