1. Honors biology
Ch.1

2. The test 65 multiple choice questions 4 short answer questions
4 open response questions with multiple sub- questions

3. Themes Evolution Energy transfer Structure and function Regulation
Communication

4. Topics Chemistry Cells Energy Genetics Evolution
Plants and animals: anatomy and physiology
Ecology

5. hierarchy
Atoms- molecules – organelles – cell – tissue – organ- organ system – organism – population – communities – ecosystem - biosphere
Emergent properties…as climb the hierachy
Cell is more than sum of it’s parts
Due to arrangement and interactions of parts
Examle: brain injury: all parts still present, but does NOT work properly

6. Hierarchy Tissue: similar cells with similar function
Organ: mult. Types of cells with complex function
Organ system
Organism
Population: all individuals of 1 species in 1 area
Community: all living things in 1 area
Ecosystem: all living and non-living things in 1 area

7. Activities of life
Cell is the lowest level capable of all activities of life
Growth
Reproduction
Response to stim
Regulation
Energy processing

8. Two types of cells Prokaryote: bacteria
Eukaryote: fungi, plants, animals

9. prokaryote Prokaryotic cells: No membrane bound organelles
What does it have?

10. eukaryote
Eukaryotic cells:
More complex
Internal membranes
nuclues

11. 3 Domains of life
Bacteria
Archaea
Eukarya

12. Regulation Feedback mechanisms Negative feedback: most common
The output or product of a process (negatively) regulates that very process
Positive feedback
Product of a process positively enhances the process

13. Evolution Introduced by Charles Darwin in the book
The Origin of Species
Current species arose from a
Common Ancestor
Descent with modification: Natural selection
Natural environment “selects” for certain traits

14. Tree of life
Family tree
Adaptive radiation

15. Data Data: recorded observations Qualitative: descriptions
Items of information on which scientific inquiry is based.
Qualitative: descriptions
(color of leaves)
Quantitative: numerical information

16. Scientific method
Hypothesis: educated supposition of what will happen when certain changes are made.
Experimental design: variable, control
Data collection: will there be qualitative (pics) or quantitative
Format results: graphs
Conclusion: what does it mean

17. DNA DNA: ALL cells contain DNA at some point
Universality of genetic code

18. Nucleotides DNA double helix 4 nucleotides A T C G Adenine Thymine
Guinine
Cyosine

19. DNA Nucleus of each human cell has entire genome
3 billion chemical letters long
