fundamental building blocks of matter are atoms and molecules. These make up elements and compounds. An atom is the smallest unit of an element that maintains the properties of that element. And element is a pure substance made of only one kind of atom. A compound is the substance that is made from the atoms of two or more elements that are chemically bonded. Water is an example of a compound because it is one of many compounds that consist of molecules. The hydrogen and oxygen molecules are chemically bonded

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
