characteristics Definition Collection of traits that form the way an organism looks 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 Memory Pictograph
chemical change Definition Change in a substance that produces a new type of substance with new chemical properites 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 Memory Pictograph
chemical weathering Definition Process by which rocks are broken down by chemical changes 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 Memory Pictograph Acid rain wears down surface by chemical action
chlorophyll Definition Chemical that is used by plants during photosynthesis 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 Memory Pictograph
chromosome Definition deoxyribonucleic acid made of strands of DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms 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) Memory Pictograph
climax community Definition Last step of a natural process called succession 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 Memory Pictograph
closed circuit Definition Electrical circuit in which electricity can flow freely 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 Memory Pictograph
cold blooded Definition Animal whose body temperature changes with the environmental temperature 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 Memory Pictograph
cold front Definition Occurs when cold air mass moves warm air mass upward 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 Memory Pictograph
community Definition Group of different populations living in the same place 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 Memory Pictograph
competition Definition Interaction between 2 organisms over basic resources such as food, water, shelter, mates 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 Memory Pictograph
compound Definition Pure substance made up of 2 or more different elements that are bonded together Facts/Examples/NonExample Have chemical and physical properties not like the original elements Always has a chemical formula EX: salt (NaCl), water (H 2 O), carbon dioxide (CO 2 ) NONEX: elements are made of just one type of atom, mixtures are made of different materials next to each other BUT NOT BONDED TOGETHER Memory Pictograph
