  1. September 18, 2013 – Bell Work • Sketch the map Sketch the map Copy the questions Choose your answers Explain each answer

  2. characteristics Definition Facts/Examples/NonExample We inherit our traits from our parents So do other organisms 50% from each parent organism EX: hair color, body shape, skin color NONEX: acquired traits such as playing a musical instrument • Collection of traits that form the way an organism looks Memory Pictograph

  3. chemical change Definition Facts/Examples/NonExample Happens because of chemical reactions Chemical bonds are broken and/ or new bonds are formed Cannot be reversed – new substances formed EX: fire, rust, baking soda & vinegar NONEX: physical change such as change in size by cutting paper or wood • Change in a substance that produces a new type of substance with new chemical properites Memory Pictograph

  4. chemical weathering Definition Facts/Examples/NonExample Man-made or natural Dissolves rocks Acids do most of the weathering and erode the surface of the rocks EX: acid rain NONEX: rocks eroded by wind or frost action which are both mechanical weathering • Process by which rocks are broken down by chemical changes Memory Pictograph Acid rain wears down surface by chemical action

  5. chlorophyll Definition Facts/Examples/NonExample Gives plants their green color In chloroplasts of plant cells Allows plants to produce their own food EX: all plants NONEX: animals do not produce their own food • Chemical that is used by plants during photosynthesis Memory Pictograph

  6. chromosome Definition Facts/Examples/NonExample Humans have 46 chromosomes 23 chromosomes from each parent “blueprint” of how to build (or repair) a particular organism EX: eukaryotes have chromosomes in the nucleus of the cell NONEX: prokaryotes have DNA but not inside of a nucleus (prokaryotes do not have a nucleus) • made of strands of DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms Memory Pictograph

  7. climax community Definition Facts/Examples/NonExample Takes a long time Lake dries up, becomes a wetland, then a meadow, then shrubs, then trees then forest Can stay as a forest for many years EX: U of M Dearborn hiking area is a beech-maple climax community NONEX: people cut down all the trees and change natural pattern • Last step of a natural process called succession Memory Pictograph

  8. closed circuit Definition Facts/Examples/NonExample Wires are fully connected into a path for electrons to flow freely Light bulbs can light up Battery is source of electron flow EX: flashlight switched on NONEX: open switch, broken wire, or burned out light bulb • Electrical circuit in which electricity can flow freely Memory Pictograph

  9. cold blooded Definition Facts/Examples/NonExample Body temperature is not constant Body temperature changes with temperature of its environment Warm and cold extremes can kill the animal EX: reptiles, amphibians, fish, invertebrates NONEX: mammals, birds • Animal whose body temperature changes with the environmental temperature Memory Pictograph

  10. cold front Definition Facts/Examples/NonExample Brings cold and unstable weather Can be fast or slow Can form dangerous clouds quickly and lead to severe weather EX: cumulonimbus clouds (tallest and possible tornado producers) NONEX: warm front – rain likely and less severe • Occurs when cold air mass moves warm air mass upward Memory Pictograph

  11. community Definition Facts/Examples/NonExample Groups of organisms affect each other in the community Creates a unique area EX: forest community, pond community, meadow community, coral reef community NONEX: population refers to just one species in a community • Group of different populations living in the same place Memory Pictograph

  12. competition Definition Facts/Examples/NonExample The more adaptations an organisms has to its environment, the less it needs to compete Some animals change their habits to have less competition EX: invasive species outcompeting native species, deer feeding at different times or on different plants NONEX: mutualism • Interaction between 2 organisms over basic resources such as food, water, shelter, mates Memory Pictograph

  13. compound Definition Facts/Examples/NonExample Have chemical and physical properties not like the original elements Always has a chemical formula EX: salt (NaCl), water (H2O), carbon dioxide (CO2) NONEX: elements are made of just one type of atom, mixtures are made of different materials next to each other BUT NOT BONDED TOGETHER • Pure substance made up of 2 or more different elements that are bonded together Memory Pictograph
