characteristicsDefinition

• 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

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

chemical weatheringDefinition

• 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

chromosomeDefinition

• 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 communityDefinition

• 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 circuitDefinition

• 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 bloodedDefinition

• 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 frontDefinition

• 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

communityDefinition

• 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

competitionDefinition

• 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

compoundDefinition

• 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 (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
