Biology Latest 2023 Graded A+ Biology The study of life Evolution the process of change that has transformed life on Earth Characteristics of Life Metabolize, Respond, Grow, Reproduce, Evolve Metaboliz, Respond, Grow, Reproduce, Evolve MR. GREy Biological Organization The study of life can be divided into different levels Emergent Properties result from the arrangement and interaction of parts within a system in an unpredictable manner Emergent properties characterize nonbiological entities. -EX; a functioning bicycle emerges only when all of the necessary parts connect in the correct way Ecology Every organism interacts with its environment, including nonliving factors and other organisms Ecology Both organisms and their environments are affected by the interactions between them Work Requires a source of energy Light, Chemical, Kinetic, or Thermal The different forms of energy Way energy flows through an ecosystem entering as light and exiting as heat Structure and function Closely related in organisms EX: a leaf is thin and flat, maximizing the capture of light by chloroplasts Nature does not easily change that which works. Important Fact about nature Cells the lowest level of organization that can perform all activities required for life All Cells Are enclosed by a membrane All Cells Use DNA as their genetic information The Ability of Cells to Divide the basis of all reproduction, growth, and repair of multicellular organisms Prokaryotic Cell DNA, No Nucleus, Membrane Eukaryotic Cell Membrane, Cytoplasm, Organelles, Nucleus Contains DNA DNA The substance of genes Genes the units of inheritance that transmit information from parents to offspring Chromosomes contain most of a cell's genetic material in the form of DNA (deoxyribonucleic acid) Evolution accounts for the unity and diversity of life Evolution unifies biology at different scales of size throughout the history of life on Earth
