Which option describes a similarity between scientific laws and scientific theories? 1.Both can change in light of new evidence. 2.Both explain how a phenomenon works. 3.Both are purely observations of nature. 4.Both are suggested explanations that are starting points.

1.Both can change in light of new evidence

2.Both explain how a phenomenon works

Explanation:

Law and theory can be defined to be part of the nature of scientific knowledge. A scientific theory is a well-established explanation for observations of the natural world which can be verified by applying the scientific method, while a scientific law is a statement obtained from repeated experimental and/or observational procedures to describe and/or predict natural phenomena. Scientific theories can change when researchers discover new lines of evidence, while scientific laws also change based on new empirical evidence.
