  1. What is Biology?

  2. The study of Living Things

  3. What does this pneumonic phrase represent? “King Henry Died By Drinking Chocolate Milk”

  4. K H D d c m Metric System Know how to convert one type of unit into another.

  5. Name the three main (basic) metric units.

  6. Meter - length Liter - volume Gram - mass Metric Ruler Graduated cylinder Triple Beam Balance

  7. Convert 25.6 cm = __?__ Km Think:

  8. 25.6 cm = _______ Km How did we get that? K H D B D C M 0.000256 0.000256

  9. What are the steps of the scientific method? What is important about a hypothesis?

  10. Scientists develop an “If, then” statement. Scientists must be able to TEST their hypothesis

  11. Normal Sun 1 Hr of Sun 2 Hrs Sun 3 Hrs of Sun Measuring plant height (growth) after 7 days. What is the INDEPENDENT VARIABLE?

  12. I.V. = Amount (Hrs) of Sun given to the plants What “I” change in the experiment.

  13. Normal Sun 1 Hr of Sun 2 Hrs Sun 3 Hrs of Sun Measuring plant height (growth) after 7 days. What is the DEPENDENT VARIABLE?

  14. D.V. = The height of the plants after 7 days The “D”ata collected.

  15. What is the control in this plant experiment?

  16. Plant that got Normal Sun

  17. What could be some constants in this plant experiment?

  18. Soil • Amount of water • Type of plant • Size of container

  19. What is QUANTITATIVE DATA?

  20. Quantitative Data that is measured and numbers are obtained Observations Hint: Quantitative has an “N” for NUMBERS

  21. What is QUALITATIVE DATA?

  22. Qualitative Data obtained using 5senses Observations

  23. Name the levels of living things.

  24. Molecule = Units that make up cells NOT LIVING

  25. Must be able to reproduce and produce fertile offspring.

  26. Name the 8…

  27. Made of at least one cell Growth and Development Obtain and Use energy Homeostasis – Maintaining a stable internal environment Evolve Adapt to its environment Have genetic code (DNA) Reproduce

  28. What is Taxonomy? Who was the “Father of Taxonomy”?

  29. What is Taxonomy? System of classifying and naming living things Who was the “Father of Taxonomy”? Linnaeus

  30. What 2 kingdoms did Linnaeus first recognize? How many taxons were in his taxonomy system? Name them from largest to smallest

  31. What 2 kingdoms did Linnaeus first recognize? Plant & Animal How many taxons (levels) were in his taxonomy system? 7 Name them from largest to smallest Kingdom, Phylum, Class, Order, Family, Genus, Species (King Phillip Came Over For Green Soup)

  32. What system did Linnaeus create to help name species? • What 2 parts are in this naming system? • What language is used in names?

  33. What system did Linnaeus create to help name species? • Binomial Nomenclature • What 2 parts are in this naming system? • Genusspecies • (scientific name) • What language is used in names? Latin

  34. Do these animals belong to the same species or genus? • Ursusarctos • Ursuscollaris • Ursusberingianus

  35. These animals belong to the same genus Ursus • Ursusarctos • Ursuscollaris • Ursusberingianus

  36. What taxon was added to make 8 taxons in the MODERN system of classification?

  37. DOMAIN was added to make 8 taxons in the MODERN system of classification

  38. How many DOMAINS ? Name them! How many KINGDOMS? Name them!

  39. How many DOMAINS ? 3Bacteria, Archae,Eukarya How many KINGDOMS? 6 Eubacteria Archaebacteria Protista Fungi Plantae Animalia

  40. Why do we classify living things? Give 4 reasons

  41. Why do we classify living things? Give 4 reasons • Universal System • (Common names are different in various locations around the world making it difficult to talk about an animal. Ex: puma, mountain lion, cougar) • Organizes living things • Easier to study living things • Looks at relationships (interactions)

  42. Traditional classification is based on ____________ characteristics. Evolutionary classification is based on ____________ characteristics. Molecular (clock) classification is based on ____________.

  43. Traditional classification is based on shared physical characteristics. Evolutionary classification is based on evolutionary(ancestors) characteristics. Molecular (clock) classification is based on DNA andtime.

  44. EVOLUTIONARYClassificationuses derived characteristics to show evolutionary descent from a single ancestor. It uses what type of tree?

  45. EVOLUTIONARYClassificationuses derived characteristics to show evolutionary descent from a single ancestor. It uses a cladogram! Hint: Looks like a hand and sounds like “clap”

  46. What is a dichotomous key?

  47. What is a dichotomous key? Lists paired choices (1.a or 1.b etc.) to lead you to the organism’s name. Be able to use one!!!!

  48. Eubacteria and Archaebacteria belong to what group of organisms: Prokaryotes or Eukaryotes? What is the difference between Prokaryotes and Eukaryotes?

  49. Eubacteria and Archaebacteria belong to what group of organisms: Prokaryotes Prokaryotes: NoNucleus or membrane bound organelles Eukaryotes: Have a nucleus and organelles
