  1. CATS Review Packet

  2. 1. What does abiotic mean? • All the non-living things in an ecosystem.

  3. 2. Give an example of biotic. • Trees • Raccoon • Grass • Tulip • Deer • Squirrel

  4. 3. What is the water cycle • The continuous movement of water from the surface of the earth to the atmosphere (troposphere).

  5. 4. What is the carbon cycle? • The continuous movement of carbon dioxide and oxygen between living things and the environment.

  6. 5. What is the Nitrogen Cycle? • The constant movement of nitrogen between living things and the environment.

  7. 6. Define Biome • A biome is a large region characterized as having a distinct climate and specific types of plants and animal life.

  8. 7. Name a characteristic of a Grassland biome? • Grassland Biome are areas in which the main plants are grasses. Summers are 86 F, Winters 32F, can support many species of animals: hawks, prairie dogs, bison, wheat and grasses.

  9. 8. Where would you find taiga biome? • Taiga Biome: South of the tundra. Much of Canada, Alaska, and North of the Rocky Mountains of the US.

  10. 9. Tropical Rain Forest • Tropical Rain forest is near the equator, warm temperatures (77F), abundant rainfall, many unique species of animals.

  11. 10. Food Chains/Food Webs • A food chain traces the path of energy as it moves from one organism to the next. Energy begins with the sun. • Food Webs are the interaction of many food chains within an ecosystem.

  12. 11. What is a niche? • The special role an organism plays within its habitat.

  13. 12. Define Carrying Capacity • The largest population that an area can support.

  14. 13. What is a vertebrate? • Animals with backbones

  15. 14. How do fish breathe? • Through Gills

  16. 15. Are reptiles warm-blooded or cold blooded? • Reptiles are cold-blooded

  17. 16. Define Symbiosis • Symbiosis: Relationship between two organisms. • Mutualism, Commensalism, and Parasitism

  18. 17. Give an example an adaptation. • Something that helps an organism get food, build a home, or protect itself. • EX: if a human cuts down the habitat of raccoons, they will adapt and learn to live in the new environment. Instead of hunting their food in the woods, they will search in other places, such as, garbage cans.

  19. 18. How is a plant cell differ from an animal cell? • Plant cells have cell walls and chloroplast. • Animals cells do not have either. • Both have cell memebranes.

  20. 19. Levels of Organization from smallest to largest in size. • CellTissueOrganOrganSystemOrganism

  21. 20. Levels of organization from specialized to least specialized. • OrgamismOrganSystemsOrgansTissuesCells • Multi-cellular-Uni-cellular

  22. 21. What is the difference between Osmosis and diffusion? • Osmosis: Diffusion of water across the memebrane (High to Low Concentration) • Diffusion: Movement of a molecule from an area of high concentration to an area of low concentration.

  23. 22. Relationship between photosynthesis and respiration. • Photosynthesis: Process that allows plants to make its own food. Takes in CO2 and gives off O2. • Respiration: O2 combines with glucose and CO2 and water is given off.

  24. 23. Father of Genetics. • GregorMendell

  25. 24. Define heredity • The passing of traits from parents to offspring

  26. 25. What does homozygous mean? • Homozygous/Pure: Same allele for a given trait. • Example: TT; tt

  27. 26. How is meiosis different from mitosis? • Meiosis: Sexual Reproduction. ½ the genetic material in cell division is passed to offspring. Only in sex cells: sperm and egg. • Mitosis: Asexual Reproduction Cell division. Where 100% of genetic material gets passed on from one parent cell.

  28. 27. What are the sex chromosomes for a woman? • XX

  29. 28. Give an example of Physical Property. • Density, Ductility, Malleability, Boiling Point, Melting Point, Electrical Conductivity. • Identifies an element or compound. • Properties that do not change for the element or compound

  30. 29. Chemical Property • Describe matter based on its ability to change into a new substance without different properties. • Flammability is a chemical property • Rusting

  31. 30. What is the building block to matter? • Atoms

  32. 31. Law of Conservation of Mass Matter can not be created or destroyed

  33. 32. Define Acid • Acid is any compound that produces H+ in water. Examples: Coffee, Tomatoes, Vinegar, Lemons, Stomach Acid. • PH scale 0-6.9

  34. 33. Define Base • Base is any compound that produces OH- in water. • Examples: Milk, Blood, Ocean Water, Antacid, Soap, Ammonia, Bleach. • PH 7.1-14

  35. 34. Neutralization • PH of 7. • Neither acidic or basic

  36. 35. Difference between Mixture and Compound • Mixture: a combination of two or more substances that have not combined chemically. They can be separated by physical means. • Compound: Matter made of two or more elements. The elements are chemically bonded; can not be separated by physical means.

  37. 36. Friction • Force that resists the motion of two surfaces that are touching each other.

  38. 37. Gravity • Force of attraction between any two objects.

  39. 38. Net Force • Combination of all the forces acting on an object.

  40. 39. Mass and Weight • Mass: amount of matter in an object measured in grams. • Weight: A measure of the force of gravity on an object.

  41. 40. Power • Power: How much work a machine can do in a unit of time.

  42. 41. 1st Class Lever • Fulcrum is in the center. Example: Door hinge, pop bottle opener • Lever: a long rigid bar that rests on and pivots around a support called a fulcrum

  43. 42. What is the boiling point of water? • 100 C

  44. 43. Name the three ways that heat moves. • From Hot to Cold • Conduction: Direct Heat • Convection: Heat transfer through air or liquid • Radiation: Heat transfer through space

  45. 44. What does renewable mean? • Regularly replaced or replenished by nature. Wind is a renewable energy source.

  46. 45. Why is electricity considered a secondary source of energy? • Sun is the source of all energy and is the primary source of all energy.

  47. 46. If a light bulbs lights up, is it a closed or open circuit? • Closed

  48. 47. What is the difference between an insulator and a conductor? • Insulator: a material that slows the movement of energy from one place to another. Ex. Thermos bottle. • Conductor: materials that let electrical charges flow through them. Ex. Metals, copper, aluminum wire.

  49. 48. What is xylem? • Plant tissue that transports water.

  50. 49. Angiosperm • Flowering plants– plants that produce flowers. Example: trees, shrubs, garden plants.
