By using a microscope, the collection of data regarding the heart rate of the how to make a line graph in word Daphnia was possible. Drinks such as coffee, Red bull, MONSTER and Coca-Cola contain high amounts of caffeine, causing the consumer to increase their amounts of stimulatory neurotransmitters (this is a chemical in the brain sent throughout the body telling your heart to beat, your lungs to breathe, and your stomach to digest).
