Explanation:

A suitable example is breathing rate. During exercise, cells need more oxygen for respiration (to produce energy) and produce more carbon dioxide. The body increases breathing rate: faster inhalation brings in more O₂, faster exhalation removes excess CO₂. This restores gas (O₂/CO₂) balance in blood, maintaining homeostasis. Another example: blood glucose levels. Exercise uses glucose for energy, so the body (via hormones like glucagon) releases stored glucose (from glycogen) to keep blood glucose within a normal range, ensuring cells get enough fuel while preventing dangerous spikes/drops.

Answer:

One example is breathing rate: During exercise, cells require more oxygen (for energy production) and produce more carbon dioxide. The body increases breathing rate—faster inhalation delivers more O₂ to the lungs (for gas exchange with blood), and faster exhalation removes excess CO₂. This restores the balance of O₂ and CO₂ in the blood, maintaining homeostasis (stable internal gas concentrations).

(Alternative: Blood glucose regulation—Exercise uses glucose for energy, so the body releases stored glucose (e.g., from glycogen) via hormones like glucagon. This keeps blood glucose levels within a normal range, ensuring cells have enough fuel while preventing dangerous fluctuations.)
