Explanation:
Scientists often repeat experiments multiple times.
Why is this important?
A.
Repeating an experiment helps to verify the results.
B.
Repeating an experiment turns a hypothesis into a theory.
C.
Repeating an experiment gives scientists something to do while they think of new hypotheses.
D.
Repeating an experiment allows scientists to test different variables.
Answer:
The answer is A.
Explanation:
Scientists repeat the same experiments because they wanna try to see if they keep getting the same result. When a scientific investigation is repeated, this is called replication. Replication is important in science so scientists can “check their work.” The result of an experiment is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
