BIOL 150 Study Guide - Final Guide: Living Systems, Paraphyly, Polyphyly
Document Summary
Explain and integrate ve overarching biological concepts: evolution, information flow, exchange, and storage, pathways and transformations of energy and matter, systems, structure and function. The biodiversity on the planet has grown and changed over time through both selective and random processes (evolution), Information (dna, for example), and signals are used and exchanged within and among organisms to direct their functioning. Dna is the instruction code for all life; how it is used and exchanged within and among life forms contributes to biodiversity (information flow, exchange, and storage). All living things require energy and rely on chemical transformations of matter to survive; some pathways are nearly universal, others vary by type of organism (pathways and transformations of energy and matter) Living systems are interconnected in organized patterns, and they interact and in uence each other on multiple levels, from cells within one organism to interactions between global communities (systems).
