  • 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.
