What is the point of a feedback loop?

• To provide the body with more energy

• To provide the body with more food

• To make sure the conditions in the body are always changing

• To make sure the conditions in the body remain stable

What is the difference between what will happen if their is too much Glucose or too little Glucose? SELECT ALL THAT APPLY

• With too much Glucose, Insulin is released. With too little Glucose, Glucagon is released.

• With too much Glucose, the pancreas produces insulin. With too little Glucose, the pancreas produces glucagon.

• With too much Glucose, Glucagon is released. With too little Glucose, Insulin is released.

• There is no difference.
