Biology is first split into 3 main branches that focus on 3 different organisms: Zoology (animals), botany (plants), and microbiolog y (organisms).
First, you need to find something that contains DNA. Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas.

Mark Haub , professor of human nutrition at Kansas State University, ate a Twinkie every three hours for ten weeks in an attempt to prove that caloric intake, rather than the healthiness of food, was the main factor contributing to weight loss, to which I reply, “Duh.” Halfway through the CNN article on the subject , it is revealed that Haub’s entire diet didn’t consist solely of junk food, but he also took a multivitamin pill, drank a protein shake, and ate some vegetables each day. The consumption patterns, an 1,800-calorie-per-day diet (for a man that should be receiving about 2,600) resulted in Haub dropping his body fat from 33.4 to 24.9 percent in two months. His other health markers improved as well, including his bad cholesterol dropping 20 percent and his good cholesterol rising 20 percent.
