Questions: Question 2 1 pts Based on your knowledge of scientific laws and theories, which of the following is true? A theory is supported by a single researcher, and laws must be supported by separate groups of researchers. A theory is an explanation for a broader concept than a law. A theory can never change, while a law changes often. A theory can turn into a law with more scientific evidence.

The answer is the second one (B): A theory is an explanation for a broader concept than a law.

Explanation for each option:

A. A theory is supported by a single researcher, and laws must be supported by separate groups of researchers.

• This is incorrect. Both theories and laws require substantial evidence and support from the scientific community, not just a single researcher. The validation process involves peer review and replication of results by multiple researchers.

B. A theory is an explanation for a broader concept than a law.

• This is correct. A theory provides a comprehensive explanation of some aspect of the natural world that is based on a body of evidence and can incorporate laws, hypotheses, and facts. Laws describe specific relationships under certain conditions in nature, often expressed mathematically.

C. A theory can never change, while a law changes often.

• This is incorrect. Both theories and laws can be modified or refined with new evidence. However, theories are more likely to be revised as they are broader and more complex. Laws, being more specific, are less frequently changed but can be refined.

D. A theory can turn into a law with more scientific evidence.

• This is incorrect. Theories and laws serve different purposes in science. A theory does not become a law; rather, a theory explains why phenomena occur, while a law describes how phenomena behave under certain conditions.

Summary: The correct answer is B: A theory is an explanation for a broader concept than a law.
