Answer :

Final answer:

Scientific experiments are constrained to a single system to control variables, ensuring accurate results and clear analysis.


Explanation:

Scientific experiments are limited to a single system to allow for controlled conditions where only selected variables are changed while others are kept constant. This isolation helps scientists study specific phenomena with clarity and precision. For example, in chemistry and biology, controlled experiments are common practice, providing valuable insights into how certain factors impact outcomes.
