Question 2 • PA Human Anatomy & Physiology A 2026-2027 SMITH IC

Which characteristics distinguish a law from a theory? Check all that apply.

Answer
A
A law begins as a testable hypothesis.
B
A law may be demonstrated mathematically.
C
A law is a statement of fact.
D
A law is only an explanation of observations.
E
A law is accepted as true based on a few experiments with similar results.

Explanation

A scientific law describes a consistent pattern or relationship in nature, often using a mathematical expression, so it may be demonstrated mathematically and is a statement of fact about what happens. A theory, by contrast, explains why or how observations occur. A law does not simply begin as a hypothesis or become accepted after only a few similar experiments.
