8. Science Scientific Method/Approach 1. Observation 2. Question 3. Hypothesis 4. Prediction 5. Gather information 6. Experiments 7. Assess results 8. Report

9. Which answer puts the steps of the scientific method in the correct order to solve a problem? 1. D  A  C  B  E 2. D  B  A  C  E 3. D  A  B  C  E 4. D  B  C  A  E A.If the problem was the yeast, then the bread should rise when I use the new yeast. B.Maybe the yeast that I used had gone bad. C.I will remake the bread using a new jar of yeast. D.The bread did not rise. E.On my second attempt the bread did rise so it is likely that the old yeast was bad.

10. Which answer below is a hypothesis for the validity of echinacea? 1. Does echinacea reduce the duration and symptoms of the common cold? 2. Echinacea reduces the duration and severity of the symptoms of the common cold. 3. If echinacea acts as above, then patients treated with echinacea at the first sign of cold symptoms should recover faster than untreated patients. 4. None of the above.

11. Which statement below is a prediction based on the following hypothesis: Echinacea reduces the duration and severity of the symptoms of the common cold. 1. If echinacea works, then individuals taking echinacea should get sick less frequently than those who are not taking it, and when they do get sick, their illness should not last as long. 2. If echinacea works, then individuals taking echinacea will have a similar rate of infection and be sick for a similar duration when compared to people who are not taking it. 3. If echinacea works, then individuals taking echinacea will not contract the flu or not have the flu as long as those who are not taking it. 4. If echinacea works, then if patients take twice the dosage it will be twice as effective when compared to those who are not taking it.

21. 2 ways in which organisms can obtain their nutrients: 1. Producers- aquire energy and raw materials from the environment photosynthesis to convert solar energy to chemical energy. (use sunlight to make sugars).

22. 2.Consumers- energy and nutrients are obtained by consuming producers and other organisms. Ex: animals Ex: animals decomposers decomposers

23. DNA (molecule)

24. Reproduction cells
