  1. 2. An experiment in which all variables are kept constant except for the independent variable being tested.
  2. 5. The smallest unit of matter that retains the properties of an element.
  3. 7. Information acquired by observation or experimentation that is used to validate scientific claims.
  4. 8. The variable that is measured in an experiment and is affected by changes in the independent variable.
  5. 9. The basic structural and functional unit of all living organisms.
  6. 11. A specialized subunit within a cell that has a specific function, such as mitochondria or the nucleus.
  7. 12. A structure composed of different types of tissues that work together to perform a specific function.
  8. 14. A group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.
  9. 15. The ability to repeat an experiment and achieve similar results, which confirms the validity of the findings.
  10. 16. The scientific study of life and living organisms, including their structure, function, growth, and evolution.
  11. 17. Any individual living entity that can react to stimuli, reproduce, grow, and maintain homeostasis.
  12. 18. The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.
  13. 20. A statement based on repeated experimental observations that describes some aspect of the universe.
  14. 22. A group of similar cells that work together to perform a specific function.
  15. 23. process by which organisms maintain a relatively stable internal environment

  1. 1. A proposed explanation for a phenomenon, which can be tested through experimentation.
  2. 3. The group in an experiment that receives the treatment or condition being tested.
  3. 4. A variable that is kept constant throughout an experiment to ensure that the results are valid.
  4. 6. The condition that distinguishes living organisms from inorganic matter, characterized by growth, reproduction, and response to stimuli.
  5. 10. a physiological regulation system in a living body that works to return the body to its normal internal state (homeostasis)
  6. 13. A well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.
  7. 17. A group of organs that work together to perform complex functions for the body.
  8. 19. The process of repeating an experiment multiple times to verify results and ensure reliability.
  9. 21. The group in an experiment that does not receive the experimental treatment and is used as a benchmark.
