Question

A(n) ______(1)_______ is a general explanation of natural phenomena supported by extensive, reproducible tests and observations. In contrast, a(n)______(2)_______ is a proposed explanation for observed events. To answer specific questions about life, biologists use a general process called the _______(3)_________.

Answer 1

A scientific theory is a well-supported explanation of natural phenomena, while a hypothesis is a testable proposed explanation. Biologists and other scientists use the scientific method to test hypotheses and gather evidence to support theories.

Step-by-step explanation:

A (1) scientific theory is a general explanation of natural phenomena supported by extensive and reproducible tests and observations, such as the germ theory of disease. In contrast, a (2) hypothesis is a proposed explanation for observed events that can be tested through scientific investigation. Once evidence supports a hypothesis, it may contribute to the development of a theory. To answer specific questions about life, biologists use a general process called the (3) scientific method, which involves asking questions based on observations, formulating hypotheses, conducting experiments, and communicating results.
