2. Semester 1-AP Biology
Mr. Traylor

3. Chapter 1
EXPLAIN
Objective: Explain the overall goals of Chapter one’s coverage of biology.
Why?
Atoms-SPONCH to all life forms
Detailed connections
Life is connected from atoms to the connectivity of the biosphere.

4. Chapter 1 AP Subject Question
Cell>tissue>organ> organ systems> organisms.
This increase in complexity is shared by all organisms
Emergent properties occur-(something new!)
ONLY one energy source
Bacteria are very simple organisms without membrane bound organelles !
A. The living world’s hierarchy and biological structures

5. Chapter 1 B. Prokaryote VS Eukaryote EXPLAIN
All organisms are composed of cells
Robert Hooke-1st named & described cells-using compound microscope
Leeuwenhoek-discovered single celled organisms.
Chapter 1
B. Prokaryote VS Eukaryote

6. Chapter 1 C. Continuity of Life
DNA allows ALL life to continue. Each DNA is composed of nucleotides A-T/G-C

7. Chapter 1
Sunlight >Producers-photosynthesize making Chemical energy which is used by consumers & eventually lost as heat and waste.
Regulation of chemical reactions w/in cells centers on protein molecules called enzymes.
Negative and positive feedback mech. Help maintain a balance or homeostasis.
D. Organisms interact w/in open environments
E. Regulatory Mechanisms maintain balance

8. Chapter 1 Charles Darwin and Evolution
EXPLAIN
Natural selection does not create adaptations, rather it screens heritable traits.- what does this statement mean?
G. Evolution one of the core themes for biology
Chapter 1 Charles Darwin and Evolution

9. Chapter 1 Scientific Process Science and Technology EXPLAIN
Deductive reasoning goes from general to specific.
Most scientific observations are made through deduction.
Science is advanced w/technology. Tech. Is improved w/science
They can help us or do harm.
Biology is multidisciplinary science.
Systems biology- are designed to make model of the behavior of the entire biological system.
Scientific Process
Science and Technology

10. Big Idea 2:
Biological systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.
Enduring understanding 2.A:
Growth, reproduction and maintenance of the organization of living systems require free energy and matter.
