  • Organism

    An individual living entity that can carry out life processes independently.
  • Homeostasis

    The process by which organisms maintain a stable internal environment despite external changes.
  • Metabolism

    All chemical reactions that occur within an organism to maintain life.
  • Regulation

    The control and coordination of life processes to maintain homeostasis.
  • Unicellular

    Organisms made up of a single cell that performs all life functions.
  • Multicellular

    Organisms composed of many specialized cells working together.
  • Autotroph

    An organism that produces its own food from inorganic substances, usually via photosynthesis.
  • Heterotroph

    An organism that obtains energy by consuming other organisms.
  • Asexual Reproduction

    A mode of reproduction involving a single parent producing genetically identical offspring.
  • Sexual Reproduction

    A mode of reproduction involving two parents contributing genetic material to produce genetically diverse offspring.
  • Taxonomy

    The science of classifying organisms based on shared characteristics and evolutionary history.
  • Domains

    The highest taxonomic rank grouping all life into Bacteria, Archaea, and Eukarya.
  • Species

    The most specific taxonomic rank; a group of organisms capable of interbreeding and producing fertile offspring.
  • Hypothesis

    A testable prediction or explanation for a scientific question.
  • Null Hypothesis

    A statement that there is no effect or difference, used as a baseline for testing.
  • Alternative Hypothesis

    A statement that there is an effect or difference, opposing the null hypothesis.
  • Controlled Experiment

    An experiment where only one variable is changed at a time while others are kept constant.
  • Constants

    Factors in an experiment that are kept the same to ensure a fair test.
  • Independent Variable

    The variable that is deliberately changed or manipulated in an experiment.
  • Dependent Variable

    The variable that is observed and measured in response to changes in the independent variable.
  • Qualitative Data

    Descriptive data that cannot be measured, such as color or texture.
  • Quantitative Data

    Numerical data that can be measured and counted.
