Unit 1 Introduction To The Study Of Life

  1. 1. KEY CONCEPT Biology is the study of all forms of life.<br />
  2. 2. biosphere = everywhere life exists<br />Earth is home to an incredible diversity of life. <br />The biosphere includes all living things and all the places they are found. <br />
  3. 3. Earth is home to an incredible diversity of life. <br />Every part of the biosphere is connected with every other part. <br />The biosphere includes many environments.<br />land environments <br />
  4. 4. Tidepool<br />Estuary<br />The biosphere includes many environments.<br /><ul><li>saltwater and freshwater environments
  5. 5. The lower the atmosphere and deep under the crust</li></li></ul><li><ul><li>Biodiversity is the variety of life.</li></ul>Biodiversity generally increases from the poles to the equator.<br />Biodiversity is greater in areas with consistently warm temperatures.<br />Biodiversity is greater closer to the equator.<br />
  6. 6. <ul><li>A species is one particular type of living thing.</li></ul>Members of a species can interbreed to reproduce. <br />There are about 2 million different living species have been identified.<br />
  7. 7. All organisms share certain characteristics.<br />Biology is the scientific study of all forms of life.<br />
  8. 8. An organism is any individual living thing.<br /><ul><li>All are made of one or more cells. </li></li></ul><li><ul><li>An organism is any individual living thing.
  9. 9. All are made of one or more cells. </li></ul>All need energy for metabolism. <br /><ul><li>All respond to their environment.
  10. 10. All have DNA that they pass on to offspring.</li></li></ul><li>KEY CONCEPTUnifying themes connect concepts from many fields of biology.<br />
  11. 11. All levels of life have systems of related parts.<br />A system is an organized group of interacting parts.<br />A cell is a system of chemicals and processes.<br />A body system includes organs that interact.<br />An ecosystem includes living and nonliving things that interact.<br />
  12. 12. Biologists study many different systems.<br />
  13. 13. Structure and function are related in biology.<br />Structure determines function.<br />Proteins with different structures perform different functions.<br />Heart muscle cells have a different structure and function than stomach muscle cells.<br />Different species have different anatomical structures with different functions.<br />
  14. 14. Organisms must maintain homeostasis to survive in diverse environments.<br />Homeostasis is the maintenance of constant internal conditions.<br />
  15. 15. <ul><li>Homeostasis is the maintenance of constant internal conditions.</li></ul>Homeostasis is usually maintained through negative feedback.<br />Negative feedback systems return a condition to its normal (set) point.<br />
  16. 16. Behaviors and adaptations can help maintain homeostasis.<br />Hollow hairs transmit light to the skin and create insulation for cold environments<br />
  17. 17. Evolution explains the unity and diversity of life.<br />Evolution is the change in living things over time.<br />The genetic makeup of a population of a species changes.<br />Evolution can occur through natural selection of adaptations.<br />Adaptations are beneficial inherited traits that are passed to future generations.<br />
  18. 18. Evolution accounts for both the diversity and the unity of life.<br />
  19. 19. KEY CONCEPTScience is a way of thinking, questioning, and gathering evidence.<br />
  20. 20. Like all science, biology is a process of inquiry.<br />Scientists make careful and systematic observations.<br /><ul><li> Scientists record observations as data.
  21. 21. Scientists form a hypothesis as a possible answer to a     question.
  22. 22. Scientists test their hypotheses and analyze their data.</li></li></ul><li>Biologists use experiments to test hypotheses.<br />Observational studies allow scientists to describe a phenomenon.<br />
  23. 23. Experimentals allow scientists to determine what causes a phenomenon.<br />
  24. 24. Experiments allow scientists to determine what causes a phenomenon.<br />By smelling something other than orange juice, it can affect a person’s sense of taste.<br />
  25. 25. <ul><li>Experimental studies allow scientists to determine what causes a phenomenon.</li></ul>Independent variables are manipulated.<br /><ul><li>Dependent variables are observed and measured.
  26. 26. Constants are conditions that are kept the same.</li></li></ul><li>A theory explains a wide range of observations.<br />Theories explain a wide range of observations and experimental results.<br />A theory is supported by a wide range of scientific evidence.<br />Theories can change based on new evidence.<br />
