1. BSC 2010
Chapter 1

2. Defining Biology Science of living organisms
Science-From Greek “to know”
Body of knowledge
Method of inquiry

3. Characteristics of Science
Deals with falsifiable concepts
Dynamic body of knowledge
Open minded approach

4. Defining Feature of Life
Composed of a cell or cells (Cell theory)
Sense and respond
Reproduce
Grow and develop
Cycle energy
Regulate- homeostasis
Display order
Contain DNA as hereditary material

5. Connections- Themes within Biology
Evolution
Change in a population over time
Natural selection
Selects for pre-existing traits
Unity
Diversity

6. Themes in Biology Emergent Properties Novel properties
Appear as higher levels of complexity are attained
Due to arrangement and interaction of parts
Not unique to life

7. Themes in Biology Correlation between structure and function
Seen at all levels of organization from atoms to biosphere

8. Themes in Biology
The cell as the basic unit of life both structurally and functionally
All cells share common characteristics

9. Themes in Biology Continuity based on DNA as heritable information
All cells contain DNA
DNA encodes all proteins found within an organism
DNA allows those codes to be passed on to progeny

10. Themes in Biology Homeostasis
Maintenance of conditions within tolerable range
Feedback regulation
Negative
Positive

11. Reductionism and Systematics
Take apart to understand
Systematics
Study interactions to understand
Ecosystem dynamics

12. Levels of Biological Organization
Atom
Molecule
Organelle
Cell
Tissue
Organ
Organ system
Organism

13. Levels of Organization
Population
Community
Ecosystem
Biosphere
? Universe?

14. Classification of living Organisms
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Specie
Binomial Nomenclature

15. Main Types of Scientific Inquiry
Hypothesis based
Scientific method
Observation
Question
Hypothesis
Prediction
Experiment
Conclusion
Discovery based
Observations- Use senses to intake data
Field studies
Information gathering without drawing conclusions

16. Types of Reasoning Inductive Deductive
Derive generalizations from a number of specific observations
Common in Discovery science
Deductive
Draw specific conclusions based on generalizations

17. Summary Evolution is the over arching concept in biology
New properties emerge at each level in the biological hierarchy
Organisms interact with their environment exchanging matter and energy
Structure and function are correlated at all levels.
Cells are the basic functional and structural unit of life
Continuity of life is based on heritable information contained within DNA
Feedback mechanisms regulate biological systems
