And without their blessings neither do i have an existence nor my book.
Many people have helped me, by generalizing my thoughts, which helped me a lot in writing this book.
Mr. Rajesh Kumar Mishra, my favorite science teacher.
Mrs. Arpana Pandey, my biology teacher.
Mrs. Rashmi Prasad, my councilor who showed me positive direction.
Lastly Pinky Ma'am, my college professor.
This book is nothing without my friends effort.
