Ill give a scientist in california conducted a series of experimental investigations to test the effect of radiation on plant growth. another scientist repeats the investigations, which produce similar results. this is important because (2 points) it encourages competition within the scientific community. different scientists apply different beliefs and opinions to data interpretation. the investigation and results are more reliable if the results can be reproduced. it scientists to prove facts when they make sure their results match.
