Answer 1

1.

1. way in which the body works to reverse a change and bring about normalcy: homeostasis

2. way in which the body works to increase changes: positive feedback system

3. division of the peripheral nervous system that controls involuntary secretions and smooth muscles: automatic system

4. division of the autonomic nervous system typically activated in stress-related situations: sympathetic nrnervo system

5. division of the peripheral nervous system that controls voluntary movement: somatic nervous system

2.
