The maintenance of an organism’s internal environment is called:

• homeostasis
• balancing
• routine

Which body system controls the body to maintain homeostasis?

• nervous

• circulatory

• skeletal

What type of feedback loop is shown?

• Positive
• Neutral
• Negative

• Tissue, organ, organ system
  
• Organ system, tissue, organs, cells
  
• Cells, tissue, organs, organ system
  
• Cells , organs, tissue, organ system

What is the point of a feedback loop?

• To provide the body with more energy
