Question

review it! all the following are true about scientific theories, except: theories must have been extensively tested. theories are based on many observations. a theory is an explanation of why something happens. a theory can be the result of one scientific investigation.

Explanation:

To determine the incorrect statement about scientific theories, we analyze each option:

• Scientific theories must undergo extensive testing (multiple experiments and observations) to be accepted, so the first option is true.
• Theories are built from a large number of observations over time, so the second option is true.
• A key aspect of a scientific theory is that it explains why a natural phenomenon occurs (e.g., the theory of evolution explains the diversity of life), so the third option is true.
• A scientific theory requires consistent results from many investigations, not just one. One investigation is insufficient to establish a theory due to the need for reproducibility and extensive testing. Thus, the fourth option is false.

Answer:

D. A theory can be the result of one scientific investigation
