Question

which example describes a theory? a proposed explanation for a phenomenon that cannot be tested for supporting or falsifying evidence a testable suggested explanation for a particular phenomenon or set of observations an established explanation for a phenomenon or group of observations that is falsifiable and is well - supported by evidence a process by which scientists investigate a natural phenomenon or group of observations to accurately explain how the natural world works

Explanation:

In science, a theory is an established explanation for a phenomenon or group of observations. It is falsifiable (able to be tested and potentially disproven) and well - supported by evidence. A non - testable explanation is not a scientific theory. A testable suggested explanation is more of a hypothesis. The process of investigation is the scientific method, not a theory.

Answer:

an established explanation for a phenomenon or group of observations that is falsifiable and is well - supported by evidence
