Guerra 1 Biology Chapter 1 outline • Biology - the scientific study of life • Evolution is process of change that has transformed life on Earth o An organism’s adaptations to its environment are the result of evolution Theme: Organization • Reductionism - complex systems are reduced to simpler components to make them more manageable to study o Virus reading • Emergent properties – properties that emerge at each level that are absent from the preceding one o result from the arrangement and interaction of parts within a system o no biological entities as well • systems biology, the exploration of a biological system by analyzing the interactions among its parts o Biosphere, Ecosystems, Communities, Population, Organisms, Organs, Tissues, Cells, Organelles, Molecules • Structure and Function - Analyzing a biological structure can give clues about what it does and how it works • The Cell - smallest unit of life that can perform all the required activities o All cells share certain characteristic o The two main forms of cells are prokaryotic and eukaryotic o A eukaryotic cell contains membrane-enclosed organelles, including a DNA-containing nucleus o Prokaryotic cells lack a nucleus or other membrane-bound organelles and are generally smaller than eukaryotic cells • Compounds v. Molecules o Compounds - made up of different elements and have different properties than t
