Cells, Water, and Chemistry
1. Describe how data from fossils and new environments argue for the evolution of new species from old species. 2. Outline the theory of natural selection. 3. Describe how diffusion of solutes results in the movement from regions of high to low concentration (down a concentration gradient). 4. Outline how electron sharing or electrical attraction differ between covalent bonds (non-polar and polar), ionic bonds, hydrogen bonds, and van der Waals interactions. 5. Draw a set of water molecules showing their polar nature, hydrogen bonds, and how these features lead to the properties of cohesion and adhesion to hydrophilic molecules. 6. Explain how water forces hydrophobic interactions between hydrophobic compounds.
