Question

1. which statement describes why formulating hypotheses is a characteristic of science? explanations must be supported by information gathered through experimentation or observation. questions must be answerable through experimentation or observation. answers to scientific questions through experimentation or observation must be repeatable. investigations must focus on questions that can be tested by experimental results.

Explanation:

Formulating hypotheses in science requires that investigations center on testable questions via experimental results. Hypotheses are predictions that can be tested, and the questions they address must be answerable through experimentation. The other options focus more on aspects like support, answer - repeatability, etc., but the key aspect related to hypothesis - formulation is the testability of the questions.

Answer:

Investigations must focus on questions that can be tested by experimental results.
