    • biochemistry


      Biochemistry is the branch of biology concerned with the chemical and physiochemical processes that occur within living organisms.
    • Divisions of Biology: Biophysics


      Biophysics is the science of the application of the laws of physics to biological phenomena.
    • icon


      Biotechnology is the exploitation of biological processes such as genetic manipulation of micro-organisms for the production of antibiotics, hormones, etc.
    • botany


      Botany is the scientific study of plants, including their physiology, structure, genetics, and ecology.
    • cell biology

      Cell Biology

      Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life.
    • Ecology


      Ecology is the branch of biology that deals with the relations of organisms to one another and their physical surroundings.
    • Evolution


      Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth (Darwinism).
    • Genetics


      Genetics is the study of genes, genetic variation, and heredity in living organisms.

    1. I absolutely love this place it has been my dream since 3rd grade to be a Marine Biologist, and I know that I still have years until I have to worry about my future, but being unprepared is scarier than anything else that I’ve been through, and I know that you don’t need an eleven year old’s validation, but you are doing a great thing… It’s people and places like this that make me think that maybe I can do it to.
      So thank you for giving me a head start.
