Selected Biology Questions asked in Previous Year Papers

Dear Readers, Biology covers a good number of questions making it an important topic to cover in SSC Exams.  Around 5-8 questions asks from Biology which surely makes it important for you to study the topic well for upcoming SSC Exams. Here are previous year questions of Biology which you should not ignore.
