Sketch the map Sketch the map Copy the questions Choose your answers Explain each answer characteristics Definition • Collection of traits that form the way an organism looks Memory Pictograph 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 chemical change Definition • Change in a substance that produces a new type of substance with new chemical properites Memory Pictograph 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 chemical weathering Definition • Process by which rocks are broken down by chemical changes Memory Pictograph 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 chlorophyll Definition • Chemical that is used by plants during photosynthesis Memory Pictograph 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 chromosome Definition Facts/Examples/NonExample • made of strands of DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms • 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 Memory Pictograph 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 closed circuit Definition • Electrical circuit in which electricity can flow freely Memory Pictograph 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 cold blooded Definition • Animal whose body temperature changes with the environmental temperature Memory Pictograph 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 cold front Definition • Occurs when cold air mass moves warm air mass upward Memory Pictograph 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 community Definition • Group of different populations living in the same place Memory Pictograph 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 competition Definition Facts/Examples/NonExample • Interaction between 2 organisms over basic resources such as food, water, shelter, mates • 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 Facts/Examples/NonExample • Pure substance made up of 2 or more different elements that are bonded together • 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 Memory Pictograph
