1. What is Biology?: The scientific study of life.
2. Proper components of the SCIENTIFIC METHOD.: Observation, Question,
Hypothesis, Prediction, Experiment, Results, Conclusion.
3. Taxonomy is the ____?: Naming and classifying of species.
4. Which Kingdom of Eukarya consist primarily of unicellular organisms?:
Protista
5. What accounts for the different breeds of domesticated dogs?: Artificial
selection.
6. Relative to prokaryotic cells, eukaryotic cells are usually ______.:
EUKARYOTIC: Larger, and MORE COMPLEX.
7. What does adaption mean in a biological context?: The accumulation of favorable
variations in a population over time.
8. What is the difference between discovery science and hypothesis driven
science?: Discover science describes natural structures and processes as accurately
as possible through careful observation and data analysis.
Hypothesis- driven science is the observation and induction of discovery science. It
stimulates us to seek natural structures and processes.

16. What are the reactants of the following chemical reaction? C6H12O6 + 6
H2O + 6 O2 + ---> 6 CO2 +12H2O: C6H12O6, H2O, and O2
17. Why is water considered a polar molecule?: The oxygen end of the molecule has a
slight negative charge, and the hydrogen end has a slight positive charge.
18. Adjacent water molecules are joined by _______ bonds.: Polar and covalent.
19. A Base ______.: Will increase the PH of a solution as it will lower the H+ ions.
