Biology is the main heading title for all aspects and branches of the study of life, where terms such as biochemistry, medicine, biophysics, anatomy, and a lot and a lot more of any science that goes after organic features come under. If we look at the origin of the word "Biology", we find that it is derived from two Ancient Greek words: "Bios", meaning life, and "Logos", meaning study or science. Together, it literally translates to "the study of life" [1]. One of the most important reasons that may attract you to the study of life is your curiosity about nature; the way it works in the scope of living organisms. You may wonder how your nervous system resets by sleeping, what the average number of bacteria reproduced in some circumstances, which aromatic plant grows faster than mint, what makes birds migrate, how the fetus develops in uterus, or which organism on Earth is the biggest.. Then you find out that you're in need to go after the answers by getting closer to watch, record, notice, and conclude [2]. 

Along with the desire of establishing an extensive learning and referral biological approach for academics, researchers, professors, and all other engaged affiliates to biology, we decided to achieve our goal through collecting both theoretical and practical scientific materials from different sources, and through the continuous reviews of the material collected to have the most truthful approach possible.
 

When we talk about biology as a general word, we find ourselves being engaged directly to the various elements of life, and since we engage to know about them, we look precisely at every unique element through its specialized scale which is appropriate enough to extract its hidden features into the light.. Biologists divided the study of biological elements into different organizations according to the difference of scales; from the global scale of the planet being pictured by satellites to the scales of life's tiniest dimensions among unicellular organisms being pictured by microscopes. Scales differentiations from each other are indicated to compensate the differentiations of the sizes of biological elements through the extents of biological studies that are been put under consideration every time we go close or far from the planet. This classified biological elements according to their scales into principal names such as Biosphere, Ecosystem, Organism, Cell, DNA, and Gene [2]. 

Biosphere is the global scale of the whole biological findings that are literally certained and watched by humans, or we can say it is the whole areas of the planet and the altitude from which that are inhabited by living things.
