  • in paper of 2018 (part 5)
    the correct answer of question no 10 is analogous organ but in your answer key homologous organ in correct but this answer is wrong analogous organ are the organ that have same structure but have different function

  • 2018 ky paper mein logical reasoning ky mcqs nhi thy?
