Correct answers:
- Monitoring heart rate and breathing during exercise
- Measuring body temperature after exposure to cold
- Recording blood pressure changes after standing up quickly

Reason: Each of these investigates rapid physiological adjustments (heart rate/ventilation, thermoregulatory responses, baroreceptor reflex) that are controlled by negative-feedback mechanisms to keep internal conditions stable. Observing hair growth over months is slow developmental/growth change, not a typical feedback response that maintains short‑term homeostasis.
