Question

question 15 1 pts physiological changes that result from sympathetic nervous system activation include: decreased blood pressure decreased oxygen to the brain increased heart rate hypothalamus question 16 1 pts during which stage of the general adaptation syndrome are several body systems activated to prepare the body for action? resistance exhaustion alarm homeostasis

Explanation:

For Question 15: The sympathetic nervous system triggers the "fight-or-flight" response, which increases heart rate, blood pressure, and oxygen delivery to vital organs. The hypothalamus is a brain structure, not a physiological change from activation.
For Question 16: The general adaptation syndrome has three stages. The alarm stage is the initial phase where the body's systems activate to prepare for action, the resistance stage involves coping with the stressor, and exhaustion occurs when resources are depleted. Homeostasis is a steady state, not a GAS stage.

Answer:

Question 15: Increased heart rate
Question 16: Alarm
