At one point in time, many people thought disease was caused by fate or by incorrect behavior. Following the invention of the microscope, bacteria were discovered. After this, a new theory of what causes disease arose that was known as the germ theory. Why was the original theory modified?

The person who invented the microscope became ill.
New evidence prompted revision to the original ideas.
The proponents of the germ theory had political power.
Newton’s third law of motion states that for every action there is an equal and opposite reaction. How does this law differ from a theory?
A theory explains a set of well tested observations; a law describes a pattern in nature.
Laws can be changed with the addition of new evidence but theories cannot.
A law explains a pattern in nature in more detail than a theory.
Theories are based on more evidence than laws.
Why is it important that scientists modify scientific theories when important new information is discovered?
to confuse other scientists
to keep the theory interesting and fresh
to keep the theory as accurate and effective as possible
to make sure the general public does not understand the theory
