Case Study: : Life on Earthand Elsewhere?
1.1 What Are the Characteristics of Living Things?
- Living Things Are Both Complex and Organized
- Living Things Respond to Stimuli
- Living Things Maintain Relatively Constant Internal Conditions Through Homeostasis
- Living Things Acquire and Use Materials and Energy
- Living Things Grow
- Living Things Reproduce Themselves
- DNA Is the Molecule of Heredity
- Living Things As a Whole Have the Capacity to Evolve
1.2 How Do Scientists Categorize the Diversity of Life?
- The Domains Bacteria and Archaea Consist of Prokaryotic Cells; the Domain Eukarya Is Composed of Eukaryotic Cells
- Bacteria, Archaea, and Protists Are Mostly Unicellular; Members of the Kingdoms Fungi, Plantae, and Animalia Are Primarily Multicellular
- Members of the Different Kingdoms Have Different Ways of Acquiring Energy
1.3 What Is the Science of Biology?
- Scientific Principles Underlie All Scientific Inquiry
- Natural Causality Is the Principle That All Events Can Be Traced to Natural Causes
- The Natural Laws That Govern Events Apply Everywhere and for All Time
- Scientific Inquiry Is Based on the Assumption That People Perceive Natural Events in Similar Ways
- The Scientific Method Is the Basis for Scientific Inquiry
Scientific Inquiry: Does Spoiled Meat Produce Maggots?
- Science Is a Human Endeavor
- Scientific Theories Have Been Thoroughly Tested
1.4 Evolution: The Unifying Theory of Biology
- Three Natural Processes Underlie Evolution
- Much of the Variability Among Organisms Is Inherited
- Natural Selection Tends to Preserve Genes That Help an Organism Survive and Reproduce
