Answer:
To establish its authenticity and reliability
Step-by-step explanation:
It is very essential for any researcher to publish his/her findings or paper in a peer-reviewed scientific journal to establish its reliability, authenticity and affirmation from others.
Once a paper gets published in any renowned journal, it can be referred by other researchers of the same sector for their own studies. In this way publication helps the peer researchers also in working forward the work that has already been done by some one else prior to them .
