Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas. But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Free Science Learning Materials. Biology.

Invasive earthworms, like the ones in this bait cup sold at stores, are spread by human activity such as fishermen dumping live bait and gardeners using live compost worms near forests.
When invasive earthworms enter a healthy hardwood forest (top photo, Wisconsin) they change the ecosystem and eventually destroy the understory plants that native species depend upon (bottom photo, Minnesota). Top: Paul Ojanen; Bottom: UMD-NRRI Shown in blue are the areas of North America covered by glaciers 11,000 to 14,000 years ago. Most of the area of glaciation was earthworm-free until European settlers introduced earthworms in the 1600s.
What are the different branches of biology. The scope of biology is enormous - it's the history of all living organisms and their role on earth.
There are many branches of biology, each focused on different aspects of research. Biology is first split into 3 main branches that focus on 3 different organisms: Zoology (animals), botany (plants), and microbiology (organisms). More information on each branch as well as numerous sub-branches are listed below in alphabetical order. Branches of Biology Agriculture - the science and practice of producing crops and livestock from the natural resources of the earth. Science & Technology. Biology.
