Which physiological outcome occurs when a hibernating marmot begins vasodilation near its arousal threshold?

💡 Explanation

When a marmot enters the arousal phase from hibernation, vasodilation occurs because blood flow increases to peripheral tissues, rapidly delivering oxygen to fuel metabolic processes and heat production. Therefore, rapid oxygen consumption increase results, rather than the alternatives, which contradict the physiology triggered during arousal from hibernation.

• Which outcome results when a fish's lamellae in the gills collapse due to sediment exposure?
• Which risk increases when avian plumage develops significant oil fouling?
• Which outcome results when seasonal food abundance influences migratory bird destination selection?
• Which developmental failure results when juvenile hormone (JH) remains elevated during the pupal stage in holometabolous insects?
• Which developmental abnormality results when larval exposure to juvenile hormone analogs induces permanent activation of imaginal discs?
