Question

A biologist in a laboratory reports a new discovery based on experimental results. If the experimental results are valid, biologists in other laboratories should be able to:

1: Repeat the same experiment with a different variable and obtain the same results.
2: Perform the same experiment and obtain different results.
3: Repeat the same experiment and obtain the same results.
4: Perform the same experiment under different experimental condition.

Answer 1

repeat the same experiment and obtain the same result

explanation...

Getting the same result when an experiment is repeated is called replication. If research results can be replicated, it means they are more likely to be correct.

Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
