DNA - correct answers A complex molecule containing the genetic information that makes up the chromosomes. Ecosystems - correct answers A biological community of interacting organisms and their physical environment. Electron - correct answers A subatomic particle that has a negative charge Emergent Properties - correct answers result from the arrangement and interaction of parts within a system Emergent Properties of Water - correct answers 1. Cohesive behavior 2. Ability to moderate temperature 3. Solid (ICE) is less than dense than liquid. 4. Solvent for aqueous solutions Energy - correct answers the ability to do work Evolution - correct answers Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms. Fundamental Properties ( 5 Unifying Themes of Life) - correct answers 1. Organization 2. Genetic Information 3. Energy and Matter 4. Interactions 5. Evolution Gene - correct answers sequence of DNA that codes for a protein and thus determines a trait Gene Expression - correct answers process by which the instructions in our DNA are converted into a functional product, such as a protein Gene Transmission - correct answers passing genetic code on to offspring Levels of Complexity - correct answers cell, tissue, organ, organ system, organism Macromolecules - correct answers Macromolecules are basically polymers, long chains of molecular sub-units called monomers. Carbohydrates, proteins and nucleic acids are found as long polymers.
