Which statement describes a law based on a tested hypothesis explains how the process occurs describes something about the natural world subject to change as new evidence is discovered

based on a tested hypothesis

Explanation:

Laws are generally based on tested hypotheses.

Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that cannot be changed.

Scientific laws are internally consistent, compatible with evidence, and are testable against a wide range of phenomenon. However, they can be reviewed as more evidences emerge that have not been known before.
