12. C. Developing and Deepening Understanding The International System of Units, commonly referred to as the SI, is the standardized system of measurement used around the world. It was developed to provide a consistent and precise way of quantifying different physical quantities. Introduction to the International System of Units (SI)

13. C. Developing and Deepening Understanding Using standard units is crucial in the field of science, as it allows for consistent and reliable measurements. When scientists and researchers use the same standardized units, it enables them to accurately compare data, replicate experiments, and build upon each other's work. This consistency and precision is essential for the advancement of scientific knowledge. Importance of using standard units for consistency and precision in science.
