Biology Semester 1 Lesson 1 Study Guide

  1. An organized approach that allows one to learn how the natural world works is called _?_



    B. Scientific Method
  2. _?_ is the idea that laws of nature orperate the same way at all places and at all times.



    A. Uniformity
  3. The act of perceiving a natural occurence using the senses is called_?_



    A. Observation
  4. A _?_ is a proposed and testable statement for the way an aspect of the natural world functions.



    C. Hypothesis
  5. A conclusion based on facts and previous knowledge is called an _?_



    D. Inference
  6. A _?_ is the best explanation for a large set of data.



    B. Theory
  7. A(n) _?_ provides a normal standard against which a scientist can compare experimental results.



    B. Control group
  8. The _?_ is identical to the control group except for one variable.



    A. Experimental Group
  9. Which of the following factors separates the control group from the experimental group?



    C. Independent Variable
  10. Which of the following factors is affected by the independent variable?



    C. Dependent variable
  11. Name six characteristics common to all living things.
    • Organization of one or more cells
    • Response of stimulis
    • Homeostasis
    • Metabolism
    • Growth/Development
    • Reproduction
  12. List the six steps of scientific method.
    • Observation
    • Hypothesis
    • Prediction
    • Experiment
    • Data collection and analysis
    • Conclusion
    • Communication of results
  13. Name two ways that organisms depend on each other.
    • Food ( nutrients )
    • Gaseous exchange
  14. Distinguish between homesostasis and metabolism.
    Homeostasis keeps the internal conditions the same constantly. Metabolism transfers verious nutrients into energy.
  15. What are two principles upon which the scientific method is based?
    • Events in the natural world have natural causes
    • Based on the idea of uniformity.
  16. Give at least three reasons why scientists need to be honest and unbiased.
    Scientists repeat experiments to verify their findings. They have to keep in mind they're always trying to disprove their ideas, prevent ideas from the past to affect experimental process and conclusion. And to avoid conflicts of interest and to preserve their credibility.
  17. List and describe the three unifying themes found in biology.
    • Unity in the diversity of life
    • Interdependence of organisms, organisms interact with eachother through the living world through ecosystems.
    • Evolution of life: Change or evolve throughout lifetime to adapt.
  18. Chemical compound that brings about cellular functions
    Biological molecule
  19. Describes an organism made of one cell
    Unicellular
  20. Group of cells that carry out a specific function
    Tissue
  21. Group of organs that carry out a specific function
    Organ system
  22. High degree of order within an organism's parts
    Organization
  23. Made of many cells
    Multicellular
  24. Smallest unit that can perform all life processes
    Cell
  25. Structure made of tissues to carry out a specific function
    Organ
  26. Tiny structure that carries out life processes inside a cell
    Organelle
  27. Define ADAPTION
    The process of becoming adapted to an environment.
  28. Define DEVELOPMENT
    The gene directed process by which an organism matures.
  29. Define DOMAIN
    The category that contains kingdoms.
  30. Define GENE
    A short segment of DNA that contains the instructions for a single trait.
  31. Define HOMEOSTASIS
    The steady-state physiology condition of the body.
  32. Define KINGDOM
    In a traditional taxinomic system, the highest taxinomic category which contains a group of similar phyla.
  33. Define METABOLISM
    The sum of all chemical processes that occur in an organism.
  34. Define PEER REVIEW
    The process in which experts in a given field examines the results and conclusions in a scientists study before that study is accepted for publication.
  35. Define BIOLOGY
    The study of life.
  36. Define ECOLOGY
    The study of the interactions between organisms and other living and nonliving components of their environment.
  37. Define ECOSYSTEM
    A community of organisms and their abiotic environments
  38. Define EVOLUTION
    A heritable change in the characteristics within a population from one generation to the next.
  39. Define EXPERIMENT
    A procedure that is caried out under controlled conditions to discover, demonstrate, or test a fact, theory, or general truth.
  40. Define NATURAL SELECTION
    The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do.
  41. Define PREDICTION
    A statement made in advance that expresses the results that will be obtained from testing a hypothesis if the hypothesis is supported.
  42. Define REPRODUCTION
    The process of producing offspring
