Exercise 48

A seed is a plant embryo packaged with a food supply. Soaking a seed in water prompts the embryo to begin respiring, metabolizing its food supply to fuel its growth. Suppose that Anna has 50 soaked seeds. She boils half of them, killing their embryos, and lets them return to room temperature. She then places the dead seeds in one container and live seeds in another. If she later measures the temperature in the two containers, will they be different? Explain your answer.
