References are very important: Allow you to acknowledge the contribution of other writers and researcher in your work Allow you to give credit to the writers from whom you have borrowed words and ideas A way to provide evidence to support your claims and conclusions Make your writing more persuasive In AS and A2 biology you will have to be able to write references. In Unit 3 question 2, the last part is usually about references This document is a guide of how to properly write references.
