  2. The four things that all living things need are… a) b) c) d) 2. Producers get their energy by… _______________________________ 3.If an organism looks exactly like a parent and has the same DNA as the parent (only has one parent); this is called ____________reproduction.

  3. 4.If two organisms look similar, but have slight differences within the species, this is called… • differentiation • variation • mutation • artificial selection 5. What animal did Charles Darwin compare between islands in the Galapagos and what did he notice?__________________________

  4. 6. Organisms that can mate and produce fertile young means they are of the same… • habitat • mutation • species • community 7. The process by which inherited traits in an organism change over many years and generations is called _________________

  5. #8-10. State which ones are examples of artificialselection or natural selection. • A type of grub begins to disappear due to people putting down pesticides and grub control. Some skunks in the area have started to catch and eat some flying insects and berries instead. The skunks’ body and nose structures change over a long time. • A dairy farmer notices certain cows give more milk. He makes sure to only place these cows in with bulls to mate. • You run a kennel and sell puppies. More people want yellow labs than black labs. You put certain colored adult labs together.

  6. 11. Give an example of how to create a state of homeostasis in these conditions: • You run a mile and you are very hot • A horse is living in northern United States and the winter is coming. • It is approaching nightfall in the desert and the lizard is getting cold. 12. Which are producers and which are consumers? cat fern oak tree mouse ostrich cow raccoon lion grape vine robin Circle carnivores, underline the herbivores, and draw a box around the omnivores.

  7. 13. Define each: • Embryological evidence • Structural evidence • Molecular evidence (genetic) 14. Describe the steps in the formation of fossils in sedimentary rock. 15. Describe how fossils form in amber.

  8. 16. Tiny bones, your appendix, and tonsils are all examples of..._______________________ 17. Mutations are…_____. • harmful • helpful • harmful, helpful, or have no effect • caused by artificial selection 18.List at least three causes of extinction.

  9. A reaction to a stimulus in an environment is called a _____________. • A type of fossil that fills in the gaps when trying to figure out a geological time of existence is called a _________________. • A__________________provides evidence about the order in which species existed. • Insect remains can be found in fossilized sap called______________and many animals and plants are found in _______________________rock.

  10. 23. Animals closely related in DNA, … • don’t match in some proteins • usually are identical • share some common ancestors • adapt through natural selection 24. The green vegetation in an area is being depleted. What can happen to the green insects in the area that were preyed upon by birds? How will this insect probably change through natural selection?
