20. One of the characteristics of living things is that they respond to externalI
changes in their environment so that their internal environment stays as stable
as possible. Why must an organism do this? Name an environmental change that
an animal must respond to in order to keep a stable internal environment. What
might happen to an organism if it could not adapt to an external change?

Answer 1

Living things respond to external changes in their environment to maintain internal stability, such as temperature regulation. Failing to adapt to external changes may lead to physiological complications or death.

Step-by-step explanation:

Living things respond to external changes in their environment in order to maintain internal stability, a process known as homeostasis. This is important because fluctuations in the internal environment can disrupt biological processes and lead to dysfunction or death. One example of an environmental change that an animal must respond to is temperature. If an organism is exposed to extreme cold without the ability to adapt, its body temperature may drop to a dangerous level, potentially causing hypothermia and other physiological complications.
