and chemical properties of organic compounds‚ however in biology‚ we investigate the importance of organic compounds and how they function in animals‚ plants‚ and the ecosystems as a whole. Context is vital in biology as we study the integration of systems in the world. Context is what allows us to use critical thinking and execute the background information we have done. In chemistry‚ however‚ context is nearly useless. It does not matter where any of the compounds take place in‚ we strictly look at
