- In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.arrow_forwardWhen an animal dies, its limbs and body become stiff because its muscles go into rigor mortis (literally, rigor mortis means “stiffness of death”).
