Study Notes
Inductive & Deductive Reasoning
- Scientists utilize inductive reasoning to draw conclusions from specific observations.
- Deductive reasoning uses general principles to make predictions about specific situations.
- The conclusion from inductive reasoning often serves as a premise for deductive reasoning.
Types of Science
- Basic science focuses on expanding knowledge for the sake of knowledge.
- Applied science uses knowledge gained from basic science to solve practical problems.
- Biology is a broad field, but different branches can be further divided into different types of science.
Properties of Life
- All living organisms share common characteristics:
- Order: Organized structures and processes.
- Sensitivity/Response to the Environment: Reactions to stimuli.
- Reproduction: Producing offsprings for continuation of species.
- Adaptation: Modifications to suit the environment.
- Growth & Development: Increases in size and complexity.
- Regulation/Homeostasis: Maintaining internal balance.
- Energy Processing: Acquiring and using energy.
- Evolution: Changes in populations over time.
Levels of Organization
- The smallest unit of life is the atom (nucleus and electrons).
- Atoms form molecules - chemical structures with at least two atoms.
- Macromolecules are large molecules formed through the joining of smaller units called monomers.
- The hierarchy of organization continues from atoms to molecules, macromolecules, organelles, cells, tissues, organs, organ systems, and finally organisms.
Carl Woese & Phylogenetic Tree
- Carl Woese's work revolutionized the classification of life.
- Previously, five kingdoms (animals, plants, fungi, protists, and bacteria) were used.
- Woese identified three domains:
- Bacteria: Prokaryotes, lack membrane-enclosed nuclei and organelles.
- Archaea: Prokaryotes, often extremophiles.
- Eukarya: Eukaryotes, including protists, fungi, plants, and animals.
Homeostasis
- Organisms maintain stable internal conditions through homeostasis.
- Examples include temperature regulation through thermoregulation.
- Organisms in cold climates (polar bears) have adaptations for insulation and heat conservation.
- Organisms in hot climates have methods (perspiration, panting) for shedding heat.
Energy Processing
- All organisms require energy.
- Some capture energy from the sun through photosynthesis.
- Others obtain energy by consuming food containing chemical energy.
