A-Level Biology


Where there's water on Earth, you find life as we know it. So if you find water somewhere else, it becomes a remarkable draw to look closer to see if life of any kind is there, even if it's bacterial, which would be extraordinary for the field of biology.

-Neil deGrasse Tyson

Biology is a study of life that teaches us about ourselves and the organic world around us. Biology provides the answers to large-scale problems, and it sees the big picture on the planet. Biology tells in detail how each and everything in the environment is linked and how the effect on one element can affect the other areas.
