some theories are developed from repeated testing of a single hypothesis. cell theory, germ theory, and the theory of evolution all have developed from the testing of multiple related hypotheses. which statement best explains why some theories develop this way?\n\na hypothesis tests many variables at once, which can lead to new hypotheses.\n\nmultiple related hypotheses will become theories before a single hypothesis does.\n\neach scientist has used different wording when developing his or her hypothesis.\n\neach experiment reveals a different piece of information that is needed to develop the theory.

Answer

Brief Explanations:

A theory is developed through multiple experiments testing related hypotheses. Each experiment provides new information that contributes to building the comprehensive theory. A hypothesis usually tests one variable at a time, so the first option is incorrect. There's no set rule that multiple - related hypotheses become theories before a single one. Word - choice by scientists isn't the main reason for theory development from multiple hypotheses.

Answer:

D. Each experiment reveals a different piece of information that is needed to develop the theory.
