Which best describes the role of communication in scientific investigations? communication can identify good scientific questions to further investigate. communication is not necessary once the data are collected because the scienctists can do the data analysis themselves. communication should not be used in planning the experimental design because the scientists want to have original ideas. communication is important because the scientists need to convince other researchers not to challenge their results.

Ill edit it to make it more readable:

1.Communication can help identify good scientific questions to further investigate.
This is the best answer!  Because different scientists have different ideas, communication is the best way to find the best idea for further questions to investigate.

2.Communication is not necessary once the data are collected because the scientists can do the data analysis themselves.
- yes, but they can do it better together! wrong!

 3.Communication should not be used in planning the experimental design because the scientists want to have original ideas.
yes, but they can have even better ideas when they communicate.- wrong!

 4. Communication is important because the scientists need to convince other researchers not to challenge their results.
- of course not, results chould be challenged to find mistakes in them!
