A student's post on photosynthesis can be reliable because he cited multiple high-quality studies from scientific journals.

When we research to show that a hypothesis or idea is true, we need to give it reliable support so that people who read our research trust the conclusions of our research, and it is considered as true knowledge.

To give reliable support to an investigation, it is necessary to resort to feasible arguments or true knowledge developed by researchers and specialists. For this, we must consult sources of reliable information.

Examples of reliable sources of information are:

  • International scientific journals
  • University research
  • Proven scientific evidence
  • Specialized books

According to the above, what the student must do so that his publication is reliable for other students is to cite reliable sources so that the knowledge he is sharing is reliable.
