AP Biology Chapter One Objectives
1. Briefly describe the unifying themes that characterize the biological sciences. New properties emerge at each level in the biological Hierarchy Organisms interact with other organisms and the physical environment Life requires energy transfer and transformation

Structure, and function are correlated at all levels of biological organization Cell is an organism’s basic unit of structure and function The continuity of life is based on heritable information in the form of DNA Feedback mechanisms regulate biological systems

Evolution: the overarching Theme of Biology
2. Diagram the hierarchy of structural levels in biological organization Biosphere
Ecosystem
Community
Population
Organisms
Organ systems
Organ
Tissue
Cell
Organelle
Molecule
Atom
3. Explain how the properties of life emerge from complex organization New properties emerge because of interactions among components at the lower levels 4. Explain the importance of regulatory mechanisms in living things. Distinguish between positive and negative feedback Without regulation, the body system becomes malfunctioned and chaotic. Positive feedback has the accumulating end product stimulating production of that product. Negative feedback has the accumulating end product slowing down production of that product. 5. Distinguish among the three domains of life. List and distinguish among the 3 kingdoms of multicellular, eukaryotic life Bacteria – most diverse and widespread of prokaryotes

Archaea – prokaryotes that live in Earth’s extreme environments Eukarya – multicellular organisms
K. Plantae – consist of terrestrial multicellular eukaryotes that carry out photosynthesis K. Fungi - organisms that decompose for nutrition
K. Animalia – multicellular eukaryotes that ingest other organisms 6. Describe the observations and inferences that lead Charles Darwin to his theory of evolution by natural selection Darwin had noticed many adaptations in...
