A scientific research paper consists of several well-defined sections : introduction , materials and methods , results , and , finally , a concluding discussion . Review papers summarize the research done in a particular field over a period of time . Biology is the science that studies life , but what exactly is life ? This may sound like a silly question with an obvious response , but it is not always easy to define life . For example , a branch of biology called virology studies viruses , which exhibit some of the characteristics of living entities but lack others .
