Semester 1-AP Biology Mr. Traylor

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.

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

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

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

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

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

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

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.
