Question

q6. (s c.6.n.3.1)
a scientist states that the law of conservation of mass is important evidence for the theory of chemical reactions. how does this example best show the relationship between scientific laws and theories?
laws explain why theories happen.
. laws describe consistent patterns, and theories use evidence to explain why those patterns occur.
theories describe patterns, while laws explain why they occur.
theories are guesses, but laws are proven true

Explanation:

Scientific laws describe consistent, observed patterns in nature. Theories use evidence to explain the underlying reasons for those patterns. The Law of Conservation of Mass describes a pattern (mass is conserved in chemical reactions), and the Theory of Chemical Reactions explains why that pattern occurs.

Answer:

Laws describe consistent patterns, and theories use evidence to explain why those patterns occur.
