Answer 1

The example that shows an organism that cannot reach homeostasis through internal changes is "A lizard is cold, and it moves to a sunny rock to warm up."

This response indicates that the lizard is relying on external environmental factors (moving to a sunny rock) to regulate its body temperature rather than internal physiological changes, as it is an ectothermic (cold-blooded) animal that relies on the environment for temperature regulation. The other examples involve internal physiological responses to maintain homeostasis.
