Gabby wondered how different liquids would affect the growth of sunflowers. To design an investigation, she planted three of the same size sunflower plants in the same type of pot. She placed all three pots next to each other where they would receive full sun. Once a day, each pot received a different liquid.
Pot A - 200 mL of coffee

What statement correctly identifies how body systems interact to maintain homeostasis?
A. After eating a meal, the circulatory system breaks down the food into usable nutrients that the excretory system can deliver throughout the body.
