Terms in this set (20)

  • Levels of classification of living organisms
    Organisms are classified from most broad to most specific levels.
  • Using a dichotomous key
    A tool used to identify organisms by answering a series of yes/no questions.
  • Bilateral symmetry
    A body plan where the left and right sides of an organism are mirror images.
  • Correctly writing the scientific name
    The genus name is capitalized and the species name is lowercase, both italicized.
  • Measuring using the metric system
    Use metric units and lab equipment to measure length, mass, and volume accurately.
  • Conversions within the metric system
    Convert between units like meters, centimeters, and millimeters using powers of ten.
  • Identification of variables in a scientific experiment
    Determine independent, dependent, and controlled variables in an experiment.
  • Components of the scientific method
    Includes observation, hypothesis, experiment, data collection, and conclusion.
  • Characteristics of enzymes as proteins
    Enzymes are biological catalysts made of proteins that speed up chemical reactions.
  • Enzyme terminology
    Terms include substrate, active site, enzyme-substrate complex, and product.
  • Materials, methods, and results from enzyme activity lab
    Lab procedures to test enzyme function and measure reaction rates.
  • Benefits of using the metric system
    Provides a standardized, decimal-based system for easy measurement and conversion.
  • Procedure results from scientific method lab
    Record observations and data to support or refute the hypothesis.
  • Purpose of scientific experiments
    To test hypotheses by controlling variables and collecting measurable data.
  • Scientific method lab activities
    Hands-on experiments to practice hypothesis testing and data analysis.
  • Enzyme activity factors
    Temperature, pH, and substrate concentration affect enzyme function.
  • Scientific experiment variables
    Independent variable is changed; dependent variable is measured; controls stay constant.
  • Using lab equipment for measurement
    Proper use of tools like rulers, pipettes, and balances for accurate data.
  • Scientific method steps
    Observation, question, hypothesis, experiment, analysis, conclusion.
  • Enzyme lab observations
    Note changes in reaction rate or product formation during enzyme tests.
