Input: Consider Input: Water is exposed to heat energy, like sunlight. The water temperature is raised above 212 degrees fahrenheit. The heat breaks down the molecules in the water. These molecules escape from the water. The water becomes vapor. The vapor evaporates into the atmosphere. 

Output: Describe the process of evaporation


Input: Consider Input: Food enters the mouth. Food mixes with saliva. Food is swallowed. Enzymes in the stomach break down the food. The food moves to the small intestine. Hormones from the pancreas move to the small intestine. The hormones create the amount of sugar in the blood from the food. The sugar in the blood travels to the body. The sugar provides energy for the muscles. 

Output: How does eating food result in energy for your muscles?


Input: Consider Input: Blood delivers oxygen in the body. Proteins and acids are broken down in the liver. The liver releases waste in the form of urea. The blood carries the urea and carbon dioxide to the kidneys. The kidneys strain the urea and salts needed from the blood. The carbon dioxide by product is transported back to the lungs. Carbon dioxide is exhaled by the lungs. 


Output: How does blood remove waste from the human body?
