The contents of the book are prepared in such a way that it will make the readers to analyze the topics we usually read in any standard or preferred textbooks in a different manner like comparing the theoretical contents with life events or any research observations. The idea behind this is the questions asked in part C of CSIR UGC NET examination conducted widely throughout India for the post of Assistant Professor and Junior Research Fellow. This book is filled with concepts regarding various subdivisions of Life Science like systematic, ecology, biochemistry, cell biology, genetics, molecular biology, immunology, physiology and evolution. Most of us did not have the practice of analysing or comparing the idea behind the results we obtain in our research and projects with the textbook contents. The main idea of Part C is to make us relate both theory and practical. This book will help the readers to prepare for Part C in a better way than to simply read textbooks that is not a fruitful idea to succeed in that section of CSIR UGC NET examination. This is the second volume of the series. Hope you all enjoy and find it useful!!!!
