A∙ Digestive
B∙ Circulatory
C∙ Endocrine
D∙ Excretory
E∙ Muscular
F∙ Nervous
G∙ Respiratory

Answer 1

The digestive, circulatory, and muscular systems work together to change the cracker into a form that can be used by the body's cells.

Step-by-step explanation:

When you eat a cracker, the digestive, circulatory, and muscular systems work together to change the cracker into a form that can be used by your body's cells. The digestive system breaks down the cracker into smaller molecules through mechanical and chemical digestion. These smaller molecules are then absorbed into the bloodstream by the circulatory system, which transports them to the body's cells. Finally, the muscular system helps move the cracker through the digestive tract and aids in the process of digestion.
