  1. Experiment
    A series of procedures to test a hypothesis.

    Def: A series of actions undertaken to collect data with which to test a hypothesis
  2. Experimental design
    The manner in which a scientist intends to conduct an experiment is called an experimental design.

    Def: Artificial situation devised to test a hypothesis
  3. Experimental variable -11
    When an experiment is done in a laboratory, all conditions can be kept constant except for an experimental variable, which is deliberately changed.

    Def: In a scientific experiement, a condition of the experiment is delibrately changed.
  4. Extinction -14
    Extinction is the death of a species or a larger taxonomic group.

    Def: Total disappearance of a species or higher group. 14, 551
  5. Family -6
    • The classification categories, DKPCOFGS?
    • Did King Paul Call Out For Good Soup?

    F- Family

    Def: One of the categories, or taxa, used by taxonomist to group species; the taxon about the genus level. 6, 258
  6. Fungus -6
    Among the fungi (kingdom Fungi) are the familiar molds and mushrooms that, along with many types of bacteria, help decompose dead organisms.

    Def : plural : Fungi

    Saprotrophic decomposer; the body is made up of filaments called hyphae that form a mass called mycelium. 6, 300
  7. gene -4
    In all organisms, the genes are made of long DNA (deoxyribonucleic acid) molecules, but even so the genes are different between species and individuals.

    Def: Unit of heredity existing as alleles on the chromosomes; in diploid organisms, typically two alleles are inherited - one from each parent. 4
  8. genus -6
    Did King Paul Call Out For Good Soup?

    G- Good - Genus

    Def:
    One of the categores, or taxa, used by taxonomists to group species; contains those species that ar most closely related through evolution, 6, 258
  9. Homeostasis -3
    The maintenance of internal conditions within certain boundaries.

    Def: Maintenance of normal internal conditions in a cell or an organism by means of self-regulating mechanisms.
  10. hypothesis - 10
    A hypothesis is based on existing knowledge, so it is much more informed than a mere guess.

    Def:
    Supposition established by reasoning after consideration of available evidence; it can be tested by obtaining more data, often by experimentations. 10
  11. inductive reasoning -10
    Inductive reasoning occurs whenever a person uses creative thinking to combine isolated facts into a cohesive whole.

    Def: Using specific observations and the process of logic and reasoning to arrive at a hypothesis.
  12. kingdom - 6
    Did King Paul Call Out For Good Soup?

    K- Kingdom

    Def:
    One of the categories, or taxa, used by taxonomist to group sepcies; the taxon above phylum. 6, 258
  13. Law - 12
    Ohers prefer the term law instead of principle. Some biologist refer to the principle of evolution, a term sometimes used for theories that are generally accepted by overwhelming number of scientist.

    Def:
    Synonym for principle - 12
  14. metabolism -3
    The term metabolism emcompases all the chemical reactions that occur in a cell.

    Def: All of the chemical reactions that occur in a cell during growth and repair -3
  15. model -11
    Scientist often use a model, a representation of an actual object. Modeling occurs when scientist use software to decide how human activities will affect climate, or when they use mice instead of humans, for say, testing a new drug.

    Def:
    Similation of a process that aids conceptual understanding until the process can be studied firsthand; a hypothesis that describes how a particular process could possibly be carried out. -11
  16. multicellular -2
    Plants and animals are multicellular and are composed of many types of cells.

    Def: Organism composed of many cells; usually has organized tissues, organs, and organ systems.
  17. natural selection -7
    In the nineteenth century, two naturalist -- Charles Darwin and Alfred Russel Wallace -- came to the conclusion independently that evolution occurs by means of a process called natural selection.

    Def:
    Mechanism of evolution caused by environmental selection of organisms most fit to environment. 7, 22, 240
  18. observation -10
    The scientific method begins with observations.

    Def:
    Step in the scientific method by which data are/is collected before a conclusion is drawn. -10
  19. order -6
    Did King Paul Call Out For Good Soup?

    O- Order

    Def:
    One of the categories, or taxa, used by taxonomist to group species; the taxon above the family level.
  20. organ - 2
    Tissues make up organs, as when various tissues combine to form a heart or a leaf.

    Def:
    Combination of two or more different tissues performing a common function. 2, 382
  21. organism -2
    Despite life's diversity, all living things, also called organisms, share certain characteristics, and these characterstics give us insight into the nature of life and help distiguish organisms from nonliving things.

    Def: Individual living things.
  22. organ system - 2
    Organs work together in organ systems; for example, the heart and blood vessels form the cardiovascular system.

    Def: Group of related organs working together.
  23. photosynthesis - 3
    Plants and certain other organisms are able to capture solar energy and carry on photosynthesis, a process that transforms solar energy into the chemical energy of nutrient molecules.

    Def:
    Process occurring usually within chloroplasts whereby chlorophyll-containing organelles trap solar energy to reduce carbon dioxide to carbohydrate. 3, 86
  24. phylum - 6
    Did King Paul Call Out For Good Soup?

    P- Phylum

    Def:
    One of the categories, or taxa, used by taxonomist to group species, the taxon above the class level. 6, 258
  25. placebo - 13
    Def: Treatment that contains no medication but appears to be the same medication as that administered to other test groups in a controlled study. 13
  26. plant - 7
    Plants (kingdom Plantae) are well known as multicellular photosynthesizers.

    Def:
    Multicellular, usually photosynthetic, organism belonging to the plant kingdom.
  27. population -9
    Individual organisms belong to a population, all the members of a species within a particular area.

    Def: Group of interbreeding individuals of the same species occupying the same area at the same time. 2, 9, 234, 552
  28. reproduction - 3
    Every type of living thing can reproduce, or make another organism like itself.

    Def: reproduce: to produce a new individual of the same kind.
  29. scientific theory -12
    The ultimate goal of science is to understand the natural world in terms of scientific theories, which are accepted explanations for how the world works.

    Def:
    Concept supported by a broad range of observations, experiments, and data. 12
  30. species - 6
    Did King Paul Call For Good Soup?

    S- Soup - species

    Def:
    Group of similarly constructed organisms capable of interbreeding and producing fertile offspring; organisms that share a common gene pool; the taxon at the lowest level of classification. 6, 258
  31. taxonomy - 5
    Taxonomy is the discipline of identifying and classifying organisms according to certain rules.

    Def:
    Branch of biology concerned with identifying, describing, and naming organisms. 5, 258
  32. test group -11
    One or more test groups are exposed to the experimental variable, but only one other group is called the control group.
