Basic unit of life-lowest level of organization Red Blood Cells Nerve Cells (neurons) Cell, Tissue, organ, Organsystem Cell Pump food and oxygen to & from all cells Responds to stimuli, controls body functions Takes in O 2 and removes CO 2. The skin Covers and Protects from infection Tissue 100% Two cells join during sexual reproduction Asexually (fission) and conjunction Yes Cell, use energy, respond to stimuli, grow, reproduce Light, water,soil, temperature, oxygen owl, badger, grouse, prairie dog, bison, grass Light, water, and CO2

Light, water,soil, temperature, oxygen owl, badger, grouse, prairie dog, bison, grass Light, water, and CO 2 Two species, one benefits, none die. One benefits-the other is unaffected The small parasite benefits and the bigger host is harmed. One benefits-the other is harmed Two species, one benefits, none die. Producer, consumer, decomposer Producer make food and decomposer breakdown material They eat food and not make it. web web chain There is more energy available lower and less energy higher up. Herbivores have more energy available to them because the eat lower on the food chain. Herbivores have more energy available to them because the eat lower on the food chain. Evaporation requires the sun A process when water falls to Earth

Slide 4

There is more energy available lower and less energy higher up. Herbivores have more energy available to them because the eat lower on the food chain. Herbivores have more energy available to them because the eat lower on the food chain. Evaporation requires the sun A process when water falls to Earth A process when water vapor turns to liquid. A process when water turns to gas slowly at the surface. Producer, consumer, decomposer Producer make food and decomposer breakdown material They eat food and not make it. web web chain sun sun Nonrenewable resources are not replaced quickly, like fossil fuels (coal, gasoline, natural gas). Renewable resources, like dam and wind energy, do not create new substances through CHEMICAL change.

Slide 5

Nitrogen N 2 & Oxygen O 2 The particles in air is shown as a percent (%) because it is a mixture. The air density and pressure is decreases with an increase in elevation, which reduces the amount of oxygen in the air.

Yes, it cannot make a new substance. Does not react or bond with other elements. Yes, it cannot make a new substance. Does not react or bond with other elements.

Revolution determines the length of our year

Slide 8

One revolution yr Rotation determines the length of our day. Revolution determines the length of our year. One rotation NO seasons Light gets spread out because the surface at the poles round (curves) away from the sun. So the light always arrives at an angle and is Always less direct at the poles.

Gas, giant, formed later, rings, fast rotation Solid surface, rocky, small, few moons, close to the sun It has NO atmosphere, or run away greenhouse effect Swirling cluster of a billion solar system.

Slide 12

Inertia Newtons First Law of Motion To start moving is a change in motion, all objects tend resist a change in motion!!! Unless there is an unbalance force To start moving is a change in motion, all objects tend resist a change in motion!!! Unless there is an unbalance force Mass Same time Yes, unless terminal velocity is reached Fluid friction that opposes motion. The maxim speed an objects reaches when falling through air. Plate tectonics

Weathering, Erosion Deposition cementation and compaction Heat and pressure Bits of rock that can erode- sand silt and clay Plate tectonics describes how volcanoes are made near subduction zones, earthquake and mountains occur at transform and converging boundaries. sediments Water, wind, rain the inner core moves inside liquid
