During a race, the body temperature of a runner increases. The runner responds by perspiring, which lowers body temperature. This process is an example of
maintaining homeostasis

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
Responses
- maintain a balanced internal environment
- digest needed substances for other body organs.
- dispose of wastes formed in other body organs.
- increase the rate of cellular communication
- maintain a balanced internal environment

can cells burst with too much water
yes

Which statement is an example of a feedback mechanism in humans?
Responses
- An increase in the level of blood sugar results in the pancreas increasing the amount of insulin it secretes.
- Increased exposure to pathogenic bacteria results in an increase in the number of red blood cells produced.
- An increase in exercise results in a decrease in the rate of respiration.
- Increased muscle activity results in a decrease in heart rate.
- An increase in the level of blood sugar results in the pancreas increasing the amount of insulin it secretes.

Which statement describes how the organization of the respiratory system and one other system interact to maintain homeostasis in the human body?
- a.
The adrenal gland, part of the endorine system, delivers nutrients to the cells of the urinary system to remove oxygen from the blood.
- b.
The brain, part of the nervous sytem, sends messages to the nerves to signal the cells of the urinary system to deliver carbon dioxide to the blood.
- c.
The diaphragm muscle, located at the base of the lungs, contracts to signal the cells of the digestive system to break down proteins.
d. The blood vessels, part of the circulatory system, deliver CO2 to the alveoli of the lungs to be removed as waste.
d. The blood vessels, part of the circulatory system, deliver CO2 to the alveoli of the lungs to be removed as waste.
