What is the main difference between a hypothesis and a theory in scientific research?(1 point)

Responses

A hypothesis can never be modified, whereas a theory is subject to change with new evidence.

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.

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.

The correct response is:

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 highlights the fundamental distinction between the two concepts in scientific research: a hypothesis is an initial, testable proposition, while a theory is a comprehensive explanation supported by extensive evidence.

Hypothesis

The correct response is:

Results

Results from experiments and observations provide the evidence needed to evaluate the validity of a theory. If new results challenge the existing theory, it may lead to modifications or even the development of a new theory.

The correct response is:

Amino acids

Amino acids are the primary building blocks of proteins. They link together through peptide bonds to form polypeptide chains, which then fold into functional proteins.

Viruses are often considered non-living entities because they cannot reproduce or carry out metabolic processes on their own. They require a host cell to replicate and hijack the cellular machinery of the host to reproduce, which distinguishes them from living organisms that can independently perform these functions. Additionally, viruses lack cellular structures and organization typical of living cells.
