Question

Which phrase describes a characteristic of a scientific law?

used to make a prediction

is a factual statement
explains an observation

Answer 1

The phrase that best describes a characteristic of a scientific law is "is a factual statement." Scientific laws are concise statements that describe phenomena consistently under certain conditions and are generally accepted as true based on repeated experimental observations. They do not explain why something happens (that is the role of scientific theories), but they describe observable occurrences.
