Which of the following are used for scientific theories: a. dependent variables b. SI units c. scientific laws d. independent variables.

Scientific theories are supported by various components and elements within the scientific framework. Among the options provided: c. Scientific laws

1. Scientific laws are principles or rules that describe observed phenomena or relationships in nature. They are often based on repeated observations and experiments and describe what happens under specific conditions. Laws provide a concise description or mathematical expression of a phenomenon but do not usually explain why or how it occurs. They are fundamental principles within scientific fields, supporting the development and validation of scientific theories.
2. Scientific theories, on the other hand, are comprehensive explanations that integrate and explain a wide range of observations, experiments, laws, and data. Theories go beyond laws by providing frameworks to understand the underlying mechanisms, causes, and relationships among various phenomena, offering explanations for why and how certain phenomena occur.
3. The other options mentioned (a. dependent variables, b. SI units, d. independent variables) are not directly associated with scientific theories. Dependent and independent variables are elements used in experiments to test hypotheses or theories, while SI units represent standardized units of measurement used in scientific research and experiments but are not specifically linked to theories or laws.
