Question

The graph below shows how the respiratory system changes as a person goes from resting to running to walking to resting again. The respiration rate is the number of breaths a person takes per minute.%0D%0A%0D%0A%0D%0A%0D%0ABased on the graph, which of the following is a function of the respiratory system?%0D%0A%0D%0AA. %0D%0Ato deliver oxygen to cells for cellular respiration at different rates so that different amounts of energy can be made when needed%0D%0A%0D%0A%0D%0AB. %0D%0Ato detect changes in the outside world through nerve impulses and send these impulses throughout the body%0D%0A%0D%0A%0D%0AC. %0D%0Ato increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells%0D%0A%0D%0A%0D%0AD. %0D%0Ato decrease a person's heartbeat during heavy activity and decrease the flow of blood to areas that will pool with blood

Answer 1

Based on the graph, the correct answer is A. The respiratory system changes its rate of oxygen intake and release (breathing rate) to deliver oxygen to cells for cellular respiration at different rates so that different amounts of energy can be made when needed.

Answer 2

Are you positive

Answer 3

Yes, I am confident that the correct answer is A. The graph demonstrates the changing respiratory rate as a person transitions from resting to running to walking, indicating that the respiratory system adjusts oxygen intake and release to meet the varying energy demands of the body.
