Introduction The Earth is home to various forms of life contributing to the endless biodiversity that we see in our daily lives. In environments around the world there are distinct correlations between the environment and adaptations acquired by the organisms that live there. It has been shown that these adaptations

Introduction General Biology:- Biology as a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ origin‚ evolution‚ distribution‚ and taxonomy. It is a vast subject containing many subdivisions‚ topics‚ and disciplines. Among the most important topics as contained in Biology are five unifying principles that can be said to be the fundamental axioms of modern biology:- 1) Cells are the basic unit

DEFINITIONS * Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy. * The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing (except virus‚ which consists only from DNA/RNA covered by protein and lipids)‚ and is often called the building block of life. Organisms can be classified

In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both
