Foreword
This is the simplest and the most useful Biology book ever made.
Your brain doesn't need complex stuff to learn basic Biology. It needs logic, organized
and well-written content. You don't need a sophisticated book to study Biology. You
need pure information.
We haven't even put any illustration in the ebook. You can easily find all the related
drawings and pictures on the internet. Your brain learns better if you try to create
abstract images in your mind instead of looking passively to given illustrations.
By studying this ebook you will get a complete overview of all main Biology subjects.
You can read this ebook at school, at home and everywhere you think that is suitable
(even in the park or at the beach).
Think of every question as a brick of knowledge you are cementing to build your
Biology culture. And indeed these questions and answers were written to build your
biological knowledge step-by-step.
If you are a teacher, you can use this book as a study guide for your students and
also to evaluate their learning.
You are free to print one copy of this ebook and turn it into a paper book for your own
use. Whenever another copy is needed, please, refer who needs a copy to our
website www.biology-questions-and-answers.com for downloading it from there; the
download is very cheap and keeps the entire process legal.
We are very proud of offering this educational resource to you!
