The pancreas produces one hormone that lowers blood sugar level and another that increases blood sugar level. The interaction of these two hormones most directly helps humans to

• digest needed substances for other body organs.

• dispose of wastes formed in other body organs.

• maintain a balanced internal environment.

• increase the rate of cellular communication.

Feedback interactions in the human body are important because they

• determine the diversity necessary for evolution to occur.

• direct the synthesis of altered genes that are passed on to every cell in the body.

• regulate the shape of molecules involved in cellular communication.

• keep the internal body environment within its normal range.

Two primary agents of cellular communication are

• chemicals made by blood cells and simple sugars.

• hormones and carbohydrates.

• hormones and chemicals made by nerve cells.

• enzymes and starches.
