Question

question 1-13
source 1
a high school football coach is concerned about his star quarterback, devin. at the end of each game, devin experiences intense fatigue and decreased coordination. his coach discovered a nutrition company called tailwind that offers a product, endurance fuel, that provides fuel to meet increased athletes’ energy demands.

select the statement below that best explains how the data in source 2 provides evidence of two subsystems working together in devin’s body during a game.

• devin’s heartbeat decreases as his breaths per minute increases
• devin’s glucose level increases as he exerts himself throughout the game.
• devin’s breathing increases to supply more oxygen to his blood as his cells release energy.
• devin’s breaths per minute decreases as he exerts himself throughout the game

Explanation:

To solve this, we analyze each option:

• Option 1: Heartbeat and breaths per minute are related, but a decrease in heartbeat with increased breathing isn't accurate as exertion increases both.
• Option 2: Glucose level doesn't increase as he exerts (it's used for energy, so would decrease or be maintained by fuel like Tailwind, but this option's logic is off).
• Option 3: When exerting, the respiratory system (breathing) increases to supply more oxygen to cells (circulatory system distributes it), which is correct as oxygen is needed for cellular respiration to release energy.
• Option 4: Breaths per minute increase, not decrease, with exertion.

Answer:

C. Devin’s breathing increases to supply more oxygen to his blood as his cells release energy.
