stress
precursor
stressor
alarm reaction
question 22
when all biological systems function smoothly and equilibrium is maintained, this state is called:
high - level wellness

homeostasis

Explanation:

For Question 21: A stressor is defined as an event or condition (physical, social, psychological) that initiates a stress reaction. Stress is the response itself, a precursor is an earlier event, and alarm reaction is a stage of stress response.
For Question 22: Homeostasis is the biological state where all systems function in balance and maintain equilibrium. High-level wellness is a broader health state, holistic refers to whole-person care, and harmonious functioning is a general term not the specific biological equilibrium state.

Answer:

Question 21: C. Stressor
Question 22: D. Homeostasis
