2. Finally a "remote control" for class! old model of remote new model of remote

3. Your remotes will be used for quizzes in both the lectures and lab. The quizzes allow us both to quickly check on your progress. The software will display immediately how the class responded to each question. Your individual answers will not be displayed.

4. During a quiz, below each question you'll see a screen similar to this. Shown above are the last 3 digits of remote ID numbers. Once you register your remote, your 5 letter screen name will appear when the computer receives your answer.

5. After everyone has answered the question, a graph similar to this will be displayed. On this graph the percentage of students choosing each answer is displayed and the correct answer is indicated by the green column.

6. First you need to register your remote and identification Go to the NWOSU or Natural Science Departmental webpages at: www.nwosu.edu or www.nwosu.edu/science/

14. You must register your remote before your screen name will be displayed and I can identify you so that you'll receive class participation points. If you have not registered, you'll just see 5 digits of your remote ID number. Please bring your remote with you to both lecture and lab each time we meet. We will be using the remotes for quizzes almost every day. Quizzes missed because of absences or nonfunctional remotes may not be made up. Yes, we will use the remotes in class on Wednesday. No, you won't need it for this week's lab, but you will need it the following week.

18. Your 1st 2 initials and last name and the last 2 digits of your NWOSU ID number Your NWOSU ID number (may change to password of your choice after 1 st login)

22. How to pass General Biology Come to lecture AND lab (You must be enrolled in a lecture section AND a lab) Read ahead Actively participate in lectures and labs - ask about those things you don't understand Don't wait until the night before an exam to study - minimum of about 4 hours per week Use more than one way of studying - read, write, draw, talk, etc. Use notes, PowerPoint and text when studying

28. What is life?

29. The quality that distinguishes a vital and functional being from a dead body. The period of time from birth to death. An organismic state characterized by the capacity for metabolism, growth, development, reaction to stimuli, reproduction, adaptation, etc.

30. ___________ - all the chemical changes which occur within a living organism. - all of the processes used by an organism to acquire, transform and use energy. ____________ – the capacity to do work Homeostasis – maintenance of the internal conditions necessary to sustain life; e.g. temperature, pH, O 2 levels, blood pressure, etc.

31. Organization in living things All living things are composed of one or more _________.

32. Cell The smallest unit of life. The smallest entity that possesses all the _____________ ____ ________.

33. ___________ A group of (usually) similar cells that work together to perform a set of functions. Examples – muscle, bone, blood, etc.

34. __________ Two or more tissues working together to perform a set of functions. Examples – heart, stomach, brain, etc.

35. Organ System Two or more ___________ working together to perform a set of functions. Examples – digestive, urinary, cardiovascular, musculoskeletal, reproductive systems, etc.

36. Organism A living thing. Must be composed of at least one cell. Its body may consist of different tissues, organs and organ systems, or a ________ _______

37. Groups of organisms ______________ – a group of similar individuals, capable of freely interbreeding and producing fertile offspring. Any problems with this definition?

38. Groups of organisms Species – a group of similar individuals, capable of freely interbreeding and producing fertile offspring. __________________ – a group of individuals of the same species living in a given area

40. Groups of organisms Species – a group of similar individuals, capable of freely interbreeding and producing fertile offspring. Population – a group of individuals of the same species living in a given area. __________________ – two or more populations of different species living and interacting in a given area.

41. Groups of organisms Species Population Community – two or more populations of different species living in a given area. ____________________– all the interacting biotic and abiotic things present in a given area; the interacting community(s) in an area and their surrounding environment.

42. ______________ The science of naming and classifying organisms. Taxonomists: name and describe the organism; attempt to determine how organisms are related to one another

43. Scientific name of a species A _____________ – consists of two parts: name of the Genus and the Specific Epithet Example – Homo sapiens Homo is the name of our genus Homo sapiens our scientific or species name

44. Taxonomic Groups Categories that organisms are placed in when classified. Illustrate how organisms are related to one another.

45. Taxonomic Groups Domains 3 different groups of biochemically and/or morphologically distinct organisms ________ – bacteria-like, extremophiles Bacteria _________ – plants, animals, fungi and protistans

46. spherical - cocci rod-shaped - baccillispiral - spirilli Domain Bacteria

47. Taxonomic Groups ______________ The broadest category recognized by some taxonomists. Contains many organisms which share general characteristics in common. Many taxonomists recognize five different Kingdoms (ignores Archaea).

48. Kingdoms ____________ – bacteria and bluegreen algae; single-celled; prokaryotic; originally contained both Bacteria and Archaea Prokaryotic – cells do not have a true nucleus; generally considered a primitive characteristic Eukaryotic – has a true nucleus

49. Kingdoms Monera – bacteria and bluegreen algae; single-celled; prokaryotic ______________ – single-celled, eukaryotic organisms some very animal-like (e.g. Amoeba), others more plant-like (e.g. algae)

50. Kingdoms Monera Protista – single-celled, eukaryotic organisms, some very animal-like (e.g. Amoeba), others more plant-like (e.g. algae); _____________ – eukaryotic; mostly multicellular; have a cell wall; are not capable of doing photosynthesis e.g. mold, mushrooms, athlete’s foot

51. Kingdoms Monera Protista Fungi ____________ – eukaryotic; multicellular; have a cell wall; capable of photosynthesis e.g. plants

52. Kingdoms Monera Protista Fungi Plantae – eukaryotic; multicellular; have a cell wall; capable of photosynthesis; e.g. plants ____________ – eukaryotic; multicellular; no cell wall; not photosynthetic e.g. animals

53. Other taxonomic groups Domain Kingdom – many similar organisms Phylum Classintermediate categories Ordereach more specific than Familythe one preceding it Genus Species – one specific type of organism

58. How do scientists study the world around them?

59. Scientific Process No one “cookbook” method for conducting science

60. Scientific Method 1 - __________ Example - Notice that many trees lose their leaves in the fall at about the same time it starts getting colder.

61. Scientific Method 1 – Observe 2 - ___________ Notice that many trees lose their leaves in the fall. Trees lose leaves because it is colder

62. Hypothesis an educated guess; our best explanation for why or how something happens; must be testable

63. Theory An explanation that has been repeatedly tested and always found to be true. Often a theory is an explanation that draws on several different hypotheses.

64. Law or Principle A fact; an absolute; an explanation that is beyond questioning. Not many laws in biology. Is evolution a scientific theory or a principle?

65. Scientific Method 1 - Observe 2 - Hypothesize 3 - ___________ Notice that many trees lose their leaves in the fall. Trees lose leaves because it is colder. Place identical trees in different environments. Collect data on results

66. Variables Factors which can change and may affect the experiment Examples?

67. Variables Factors which can change and may affect the experiment Examples? Temperature, Water, Fertilization, Light, etc.

68. ____________ Variables that are kept constant during the course of an experiment. Usually only one variable at a time is allowed to change. Why only one?

69. Scientific Method 1 - Observe 2 - Hypothesize 3 - Experiment 4 - __________ __________ Use statistics to compare trees’ responses (analyze data) Publish results

70. Scientific Method 1 - Observe 2 - Hypothesize 3 - Experiment 4 - Objective Evaluation 5 - __________ ___ __________ Try a new test of hypothesis, or a different test of the existing hypothesis

71. Study Suggestions Try the test questions at the end of each chapter. Make certain you are familiar with the list of terms at the end of each chapter. Use your notes as an indication of what topics are most likely to be on exams. Study prior to each class meeting.
