E) Why is it important to test a hypothesis in scientific research? (1 point)

Question

To avoid the need for further experimentation.
To prove that the hypothesis is correct beyond any doubt.
To ensure the hypothesis aligns with pre-existing theories.
To gather empirical evidence that supports or refutes the hypothesis.
F) What is the best definition of a scientific theory? (1 point)
A detailed description of a scientific experiment
A well-substantiated explanation of an aspect of the natural world that is based on a body of
evidence and has been repeatedly confirmed through observation and experimentation
A tentative guess about the natural world that has yet to be tested
An educated guess
G) Why can scientists never fully prove a scientific theory? (1 point)
Because scientific theories are based on opinions and beliefs.
Because scientific theories are not based on empirical evidence.
Because theories are only applicable to specific, unchanging conditions.
Because new evidence or perspectives can always emerge, potentially challenging the existing
theory.
H) What is the main difference between a hypothesis and a theory in scientific research?
(1 point)
A hypothesis is a well-substantiated explanation of natural phenomena, while a theory is an
educated guess that needs to be tested.
A hypothesis can never be modified, whereas a theory is subject to change with new evidence.
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.
A hypothesis is a tentative explanation that can be tested by experiments while a theory is well-
substantiated explanation based on a body of evidence.
