Document Summary
Structural hierarchy in the molecular organizaion of cells: the cell and its organelles, supramolecular complexes-chromosomes, plasma membranes, cell wall, macromolecules-dna, protein, cellulose, monomeric units-nucleoides, amino acids, sugars. Emergent properies result from the arrangement and interacion of parts within a system. Example; a funcioning bike emerges only when all of the necessary parts connect in the right way. Elements are substances that cannot be broken down to other substances by chemical reacions. Mater-pure substances-elemental substance: consists of a single element. Oxygen, carbon, hydrogen and nitrogen make up 96. 3% of our bodies. The remaining percents are the other eight elements discusses before. Smallest paricles that retain properies of an element. Each element consists of a certain kind of atom that is diferent from those of other elements. The nucleus is small and dense; it was thought for a while to be fundamental. All nuclei are made up of charged protons and neutral neutrons.
