what is the main difference between a hypothesis and a theory in scientific research?

Question

a a hypothesis is a well-substantiated explanation of natural phenomena, while a theory is an educated guess that needs to be tested
b a hypothesis is a general principle that explains a wide range of phenomena, while a theory is a specific prediction about the outcome of an experiment
c a hypothesis can never be modified, wheras a theory is subject to change with new evidence
d a hypothesis is a tentative explanation that can be tested by experiments, while a theory is a well-substantiated explanation based on a body of evidence

Answer 1

The correct answer is:

d) a hypothesis is a tentative explanation that can be tested by experiments, while a theory is a well-substantiated explanation based on a body of evidence.

This distinction highlights that hypotheses are initial ideas that can be tested through research, while theories are comprehensive explanations that have been supported by extensive evidence and research.
