9 A physical or chemical change in an organism’s internal or external environment

10 What is a stimulus?

11 Maintaining a stable internal environment

12 What is homeostasis?

13 Total of all the chemical reactions in an organism

14 What is metabolism?

15 Process where organisms become mature adults

16 What is development?

17 Two “E’s” required by all organisms

18 What are Energy and Enzymes?

19 Chemical compounds that provide physical structure in organisms

20 What are biological molecules?

21 High degree of order between an organism’s internal and external parts

22 What is organization?

23 Smallest unit that can perform all life’s processes

24 What is a cell?

25 Structures that carry out specialized jobs within an organ system

26 What is an organ?

27 Group of cells that have similar abilities and that allow an organ to function

28 What are tissues?

29 The process in which all organisms produce new organisms like themselves

30 What is reproduction?

31 Large molecule containing the hereditary code for an organism

32 What is DNA?

33 Hereditary information from two individuals is combined in their offspring

34 What is sexual reproduction?

35 Daily Double!!

36 A short segment of DNA that codes for a protein or polypeptide

37 What is a gene?

38 Single organism divides producing genetically identical cells

39 What is asexual reproduction?

40 Branch of biology that studies organisms interacting with each other & their environment

41 What is ecology?

42 Communities of organisms and their physical environment

43 What is an ecosystem?

44 The rules that govern how cells use the hereditary instructions in their DNA

45 What is the genetic code?

46 The three domains of life

47 What are Archaea, Bacteria, and Eukarya?

48 The six Kingdoms of life

49 What are Archaebacteria (Archaea), Eubacteria (Bacteria), Protista, Fungi, Plantae, and Animalia?

50 Traits that improve an individual’s ability to survive and reproduce

51 What are adaptations?

52 Organisms with favorable traits survive & reproduce to pass on their genes

53 What is natural selection?

54 Helps us understand how populations of organisms came into existence & how they’ve changed over time

55 What is evolution?

56 Rabbits with white fur and short ears in snow would be an example

57 What are adaptations?

58 Daily Double!!

59 Also known as “Descent with Modification”

60 What is Darwin’s idea of evolution?

61 Organized approach used in science to explain observations of the natural world

62 What is the scientific method?

63 First step in a scientific study

64 What is observation of the natural world?

65 A statement that proposes an explanation to a scientific question

66 What is a hypothesis?

67 A group in an experiment that is used for comparison

68 What is the control?

69 Numerical data collected in a scientific experiment

70 What is quantitative data?

71 Final Jeopardy

72 Measurement

73 Metric unit most likely to be used to measure the size of a cell

74 What are micrometers?
