11. What is the unifying theme in biology? • Cellular Energetics • Ecology • Evolution • Heredity

12. Which of the following is NOT a central activity of biology? • Asking Questions • Understanding Interactions • Scientific Inquiry • Data Analysis

13. All the following are questions biologists attempt to answer except • Life Meaning • Life Process • Life Diversity • Life Complexity

14. Learning biology is mostly memorizing facts. • True • False

15. Photosynthesis not proceeding in a mixture of photosynthetic components is an example of • Evolution • Order • Response to Environment • Emergent Properties

16. Reductionism makes studying complex systems easier. • True • False

17. The purpose of systems biology is • Analyze genomes • Simplify complex systems • Understand complex systems • Analyze inputs or outputs of a system

18. Reductionism vs. Systems Biology • Reductionism breaks down into individual pieces to discover the part. • Systems biology puts the pieces and interactions together to learn about the whole.

19. All the organisms on campus make up • Ecosystem • Community • Population • Experimental Group • Taxonomic Domail

20. Which is the correct order from an organism down in hierarchy? • Brain, organ system, nerve cell, nervous tissue • Organ system, nerve tissue, brain • Nerve system, brain, nerve tissue, nerve cell

21. Hierarchy & Order (big to small) • Biosphere • Ecosystem • Communities • Populations • Organ Systems • Organs • Tissues • Organelles • Cells • Molecules

22. Protists and bacteria are grouped in different domains because • Protists eat bacteria • Bacteria are not made of cells • Protists have endomembranes • Bacteria decompose protists • Protistsphotosynth.

23. Positive feedback slows/eliminates a process. • True • False

24. Positive vs. Negative Feedback • Positive feedback speeds a process up. • Negative feedback slows a process down.

25. Positive Feedback Product Z binds to enzyme 5 and increases the rate of the reaction.

26. Negative Feedback Product D binds to enzyme 1 and slows the process by inhibiting A from binding to the enzyme.

27. Themes in Biology • Properties emerge at each level of hierarchy. • Organisms interact with organisms and environment. • Life requires energy transfer and transformation. • Structure and function are correlated at all levels of biological organization. • Cell is the basic unit of life. • Continuity of life depends on transfer of DNA to next generation. • Feedback mechanisms regulate biological systems.

28. Wrap-Up 9/5 • Why is evolution the unifying theme in biology? -OR- • How does a specific area of science/biology support the concept of evolution?

29. Important Information 9/6/13 • Get Started: • Take out your 1.2 Evolution reading notes. • Purpose: • LO 1.12 Connect scientific evidence from many scientific disciplines to support the modern concept of evolution. • Practice: • 1.3-1.4 Science Process & Application Due Mon 9/9 • CH 1 Pre-quiz Due Tues 9/10

30. The core idea that makes sense of the unity and diversity of life is • Scientific Method • Inductive Reasoning • Deductive Reasoning • Evolution • Systems Biology

31. Which of the following contains the greatest number of species? • Insects • Fungi • Plants • Vertebrates

32. The discipline of biology that classifies organisms is called • Systems Biology • Speciation • Evolution • Taxonomy

33. Three Domains of Life

34. What do you know about each domain of life? • Bacteria • Archaea • Eukarya

35. Tree of Life

36. Taxonomic Organization

37. Which best demonstrates the unity among all organisms? • Matching DNA nucleotide sequences • Descent with modification • Structure & function of DNA • Natural Selection

38. Unity in the Diversity of Life • Universal Code – DNA • Universal Structures – Cell Membrane • Universal Functions …

39. Darwin’s Ideas • Descent with Modification • Natural Selection • Heritable Traits • Not All Offspring Survive • Most Fit Individuals Survive • Out Survive +/or Out Reproduce

40. Natural Selection

41. Relatedness of Species

42. Wrap-Up 9/6 • Why is evolution the unifying theme in biology? -OR- • How does a specific area of science/biology support the concept of evolution?

43. Important Information 9/9/13 • Get Started: • Take out your 1.3-1.4 Science Process & Application Notes. • Purpose: • Understand the process & applications of science. • Practice: • CH 1 Pre-quiz Due 9/12 • Lab Notebook Guidelines: bring lab notebook (composition book tomorrow)

44. What is science? • A philosophy and process developed to understand the natural world. • Explains the what or how but not the why.

45. Science Process • We inquire, question, hypothesize, investigate, collect data, analyze data, AND … • Do our best to correlate our data with how the natural world works. • We must be very careful with reporting data. • Inductive Reasoning vs. Inference

46. Data: Qualitative vs. Quantitative Qualitative (Observation) Quantitative (Numerical) Data Tables Graphs Calculations Statistics

47. Hypothesizing Hypothesis Null Hypothesis Prediction opposing the hypothesis The null hypothesis is supported if there is NOT statistical significance to support hypothesis • Prediction + Reason • Deductive Reasoning based on general observation • Testable using science methods • Supported or Not Supported via data • Statistical Significance

48. Experimental Design • Develop a question based on general observations. • Hypothesize • Develop and document a controlled experiment. • Variables: Independent, Dependent, & Controlled • Experimental Control • Collect and analyze data. • Communicate findings.

49. Developing Theories • Scientific understanding based on a plethora of scientific research and data. • Generally always hold true … until they don’t. • Continually tested through future scientific research and data in a variety of ways.
