Electrolytes are materials that dissolve in water to form an electrically conductive solution. Electrolytes are often salts, which form ions that carry current in the solution. They are important to the body because they regulate nerve and muscle function. Electrolytes are released in sweat, so they are found in sports drinks. Which of these components of sports drinks are both electrolytes?

• Sucrose and Sodium
• Dextrose and Potassium
• Potassium and Sodium
• Dextrose and Sucrose

• The level of carbon dioxide in the blood
• The level of carbon dioxide in the cells
• The level of carbon dioxide in the lungs
• The level of carbon dioxide in the air.

• Endocytosis
• Exocytosis
• Facilitated Diffusion
• Osmosis

Which is a feedback mechanism the human body uses to maintain homeostasis?

• Copying genetic material during cell division
• Rejection of a flu vaccine by the immune system
