Answer:
Laws are created based on repeated experimentation.
Laws are based on observations.
Laws explain observations.
Explanation:
The complete question is..
Which statements correctly describe laws? Check all that apply.
-Laws are created based on repeated experimentation.
-Laws are based on observations.
-Laws explain observations.
-Laws are factual statements.
-Laws can be changed or replaced
Laws are based on the results of repeated experimentation, and observation, and they describe or predict some phenomenon in nature. Laws can't be said to be factual, as they might be seen to be constrained, or restricted and might need to be extended by future observations. Established laws explain observations, and laws cannot be changed or replaced, but can be extended, to predict future observations.
