1 What is Biology?

2 The study of living things

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

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

5 Name the four main types of basic metric units.

6 Meter - Length Liter - Volume Gram - Mass Celsius - Temperature

7 Is cubic centimeter a metric unit? YES or NO
What is a cubic centimeter a measurement for? Length, Volume, or Mass ? 1 cm high x 1 cm long x 1 cm wide = 1 cm³ Is cubic centimeter a metric unit? YES or NO

8 Is cubic centimeter a metric unit? YES!!!
What is a cubic meter a measurement for? Volume 1 cm high x 1 cm long x 1 cm wide = 1 cm³ Is cubic centimeter a metric unit? YES!!!

9 Convert 25.6 cm = __?__ Km

10 25.6 cm = _______ Km How did we get that? K H D B D C M 0.000256

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

12 Observation Problem/Question Hypothesis Experiment Data Analysis
Scientists observe the world and want to know why things happen Observation Problem/Question Scientists develop an “If, then” statement. Scientists must be able to TEST their hypothesis Hypothesis Experiment Scientists test their hypothesis Scientists look at their data Data Analysis Was their hypothesis supported or refuted? Why or why not? Conclusion Scientists want others to know and they can also test the findings Report Findings

13 What is the INDEPENDENT VARIABLE?
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?

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

15 What is the DEPENDENT VARIABLE?
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?

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

17 What is the control in this plant experiment?

18 Plant that got Normal Sun Experimenter selected control

19 What could be some constants in this plant experiment?

20 CONSTANTS These items all stay the same from one plant to the next
Soil Amount of water Type of plant Size of container CONSTANTS These items all stay the same from one plant to the next

21 What is QUANTITATIVE DATA?

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

23 What is QUALITATIVE DATA?

24 Qualitative Data obtained using 5 senses
Observations

25 What is a THEORY?

26 What is a THEORY? A well tested hypothesis that is supported by repeated testing.

27 Which is the Zoologist and which is the Botanist?

28 Which is the Zoologist and which is the Botanist?

29 Name the levels of living things.

30 Biosphere = All areas of earth with life
Ecosystem = Living and non-living in an area Community = Different species in an area Population = Same species (organisms) in an area Organism = Group of organ systems make up this Organ system = Group of organs working together Organ = Group of tissues working together Tissue = Group of cells working together Cell = SMALLEST LIVING THING!!! Molecule = Units that make up cells NOT LIVING

31 What is the main definition of a species?

32 What is the main definition of a species?
Must be able to reproduce and produce fertile offspring.

33 Name the 8…

34 Made of at least one cell
Grow and Develop Metabolism - Obtain and Use energy Homeostasis – Keeping the body in balance Evolve Respond/Adapt to the environment Universal genetic code (DNA) Reproduce

35 What is Taxonomy? Who was the “Father of Taxonomy”?

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

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

38 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)

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

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

41 Do these animals belong to the same species or genus?
Ursus arctos Ursus collaris Ursus beringianus

42 These animals belong to the same genus Ursus
Ursus arctos Ursus collaris Ursus beringianus

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

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

45 How many DOMAINS ? Name them!
How many KINGDOMS? Name them!

46 6 Eubacteria 3 Bacteria, Archae, Eukarya How many KINGDOMS?
How many DOMAINS ? 3 Bacteria, Archae, Eukarya How many KINGDOMS? 6 Eubacteria Archaebacteria Protista Fungi Plantae Animalia

47 Why do we classify living things?
Give 4 reasons

48 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) between organisms

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

50 Traditional classification is based on shared physical characteristics.
Evolutionary classification is based on evolutionary (ancestors) characteristics. Molecular (clock) classification is based on DNA and time.

51 EVOLUTIONARY Classification uses derived characteristics to show evolutionary descent from a single ancestor. It uses what type of diagram?

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

53 What is a dichotomous key?

54 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!!!!

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

56 Eubacteria and Archaebacteria belong to what group of organisms:
Prokaryotes Prokaryotes: No Nucleus or membrane bound organelles Eukaryotes: Have a nucleus and organelles

57 What are autotrophs and what kingdoms do they belong?
What are heterotrophs and what kingdoms do they belong?

58 What are autotrophs? They make their own food (energy) mostly by photosynthesis (Plants, Some Protista, Some Archae, Some Bacteria) What are heterotrophs? They must consume their food for energy (Animals, Fungi, Some Archae, Some Bacteria, Some Protista)

59 What organism was first thought to be in the Plant Kingdom?

60 Fungi What organism was first considered to be in the Plant Kingdom?
Fungi are heterotrophic and do not make their own food, so they can’t be in plant kingdom

61 What are extremophiles? What Kingdom are they from?

62 Kingdom = Archaebacteria
Extremophiles = bacteria that can live in extreme conditions (hot, cold, salty) Kingdom = Archaebacteria

63 What is metabolism?

64 Process of gaining and using energy
What is metabolism? Process of gaining and using energy

65 Know the key points of the
Classification of Living Things Chart that you were given in class and be able to use one to identify information from it.
