Presentation Transcript

  1. 1. Unicellular= one cell Multicellular=many cells differenciated • Trees [any plants]; any animals; some fungi • Bacteria [bacterium is singular]; yeast; ameba; protists [single cell eukaryotes] • Increase in size

  2. 5. Changes in an organism throughout it’s lifetime. • 6. Maintaining internal conditions necessary for life. Example: Blood sugar; temperature; pH balance; water balance

  3. 7a. Adaptation • b. Cells • c. Development • d. sexual reproduction • e. Asexual reproduction • f. Complex chemistry • g. Energy use • h. Adaptation

  4. 8. Changes in a species over time. • 9. A group of organisms that interbreed and produce fertile offspring. • 10. Anabolism builds complex substances from simpler ones. Catabolism breaks complex substances into smaller ones. • 11. The species would become extinct.

  5. 12. Stimulus= increased exercise • Response= increase in breathing rate • The eight characteristics of life. • The sun • Homeostasis • Sexual reproduction: Two parents, offspring is genetically unique Asexual reproduction: One parent; offspring is a clone • The study of what is right and wrong.

  6. Theory: Based on repeated verification of a hypothesis. Explains how something happens. Law: States that something happens. 19. Observations [made with the 5 senses] 20. Our five senses • Data. Qualitative and Quantitative • A process of thinking and learning about our world

  7. 23. Observation Problem Hypothesis Design an Experiment Collect and Analyze Data Conclusion Communicate Further investigation

  8. 24. Yes. Science cannot answer questions of philosophy or opinion. Science can only answer questions that are testable using the scientific method. • Example: Is spilling salt bad luck? 25. If…then…because 26. The variable intentionally changed by the investigator.

  9. The group where all conditions are kept the same. It provided a baseline for comparison. • Hypothesis Experiment: IV=Different pH values DV=Growth of the earthworms. Control group= group at pH 7/neutral Controlled variables: type of worms, time treated with acid rain, type of container, temperature, amount of water, amount of light

  10. C • A • No goggles/ test tube pointed toward face. 32. Meters • Liters • 10 • Weight • Pippette

  11. ` • a. Test tube rack b. Tongs C. Erlenmeyer flask d. Petri dish e. graduated cylinder • 4 ml • 25 ml • 10o

  12. 41 a. Study of life b. Study of structure of living organisms c. Study of past life through fossils d. Study of function in living organisms e. Study of interactions between living organisms and the environment. f. Study of reptiles and amphibians g. Study of fungi h. Study of heredity/ traits. i. Study of microscopic organisms j. Study of animals k. Study of plants
