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.

the investigation and results are more reliable if the results can be reproduced.

Explanation:

As you may already know, a scientific experiment is a set of procedures performed by a scientist who seeks to find answers to a particular phenomenon or situation. Every experiment, therefore, generates a result that seeks to explain a certain thing.

It is common and even recommended that scientists reproduce each other's experiments. This is because if, for example, an experiment done by me results in the same conclusions as an experiment done by you a few years ago, it means that the results of our experiments are credible and that they can be considered as correct and true.

answer: h+ its less than oh

explanation:

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
