Biology Quiz on Speciation for NEET & Medical Exam 2021

Biology Quiz on Speciation

Biology Quiz on Speciation: NEET is the most coveted medical entrance examination carried out across the country. It is an objective type, pen-paper test comprising 4 sections – Physics, Chemistry, Botany and Zoology. The maximum marks that can be scored are 720 marks and consists of 180 questions. 50% of the paper is dedicated to Biology, as the NEET exam primarily aims at enabling students to take up seats in medical courses. Biology is one of the most important and vital sections in NEET. It includes theories, descriptions, discoveries, diagrams, definitions, explanation of differences and relations. Most of the concepts covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12. In this post we are providing you biology quiz on Speciation.
