Study Notes
Introduction to Bio 111
- The course explores evolution, biological themes, and scientific inquiry
- The agenda covers cell theory, requirements of life, biological organization, principles of evolution, and the scientific method
Properties of Life
- Biology is the scientific study of life
- Key properties of life include: order, evolutionary adaptation, regulation, energy processing, growth and development, response to the environment, and reproduction
Order: Structure
- Organisms exhibit complex organization at various levels
Evolutionary Adaptation
- Organisms adapt to their environments over time through evolutionary changes
Regulation
- Organisms maintain stable internal conditions (homeostasis) through regulatory mechanisms, such as the circulatory system
Energy Processing
- Organisms obtain and use energy to power their life processes
Growth and Development
- Living things increase in size and complexity, following specific developmental pathways
Response to the Environment
- Organisms react to stimuli in their surroundings
Reproduction
- Living things reproduce to create new individuals of the species
Levels of Biological Organization
- The biosphere includes all life and its environments
- Ecosystems include all living and non-living components interacting in a specific area
- Communities are all the organisms inhabiting a specific ecosystem
- Populations are groups of individuals of the same species inhabiting a region where they can interbreed
- Organisms are individual living things
- Organs are body parts composed of multiple tissues, with specific functions
- Tissues are groups of cells with specific functions
- Cells are the fundamental units of structure and function of life
- Organelles are functional components inside cells
Organelles
- Specific functional parts of a cell include: Endoplasmic Reticulum, Mitochondria, Centrioles, Cytoskeleton, Cytosol/Cytoplasm, Plasma Membrane, Golgi Complex, Lysosome, Nucleus, Nucleolus
Molecules
- Molecules are chemical structures composed of two or more atoms, fundamental to life
- A molecule can have atoms of the same or different elements
Systems Biology
- Systems biology analyzes interactions between components in biological systems
Structure and Function
- Structure and function are central concepts in biology
The Cell
- All living organisms are made of cells, the basic unit of life
- Eukaryotic cells contain membrane-enclosed organelles and a nucleus
- Prokaryotic cells lack a nucleus and other membrane-bound organelles
DNA
- Genes are units of heredity encoded in DNA
- DNA is a double helix of nucleotides
- Transcription converts DNA into mRNA, which in turn directs protein synthesis
Genomics
- Genomics studies whole sets of genes in organisms
- Proteomics studies sets of proteins and their properties
Life Requires Energy and Matter Transfer
- Life requires the transfer and transformation of energy and matter
- Producers (photosynthetic organisms) convert energy from the sun into usable compounds
- Consumers feed on other organisms or their remains for energy
Energy Transformation Concepts
- Metabolism is the sum of all chemical changes in a living organism
- Homeostasis is the tendency toward a relatively stable equilibrium among interdependent elements in biological systems
Molecules: Interactions within Organisms
- Organisms regulate processes via feedback mechanisms
- An example of this is blood glucose regulation by insulin
Evolution: Unity and Diversity
- Evolution is the accumulation of differences in species over time (adaptations to environments)
Three Domains of Life
- Bacteria and Archaea are prokaryotic organisms
- Eukarya include organisms with eukaryotic cells divided into four kingdoms (plants, animals, fungi, protists)
Charles Darwin : Natural Selection
- Natural selection describes how traits are selected for survival and propagation, leading to adaptation
Scientific Study
- Scientific study involves inquiry, exploration, and observation, gathering and analyzing data, using inductive reasoning, and hypothesis formation to test proposed explanations
- A scientific experiment tests hypotheses under controlled conditions
Variables and Controls
- A controlled experiment compares experimental groups to control groups using variables:
- The independent variable is altered by researchers
- The dependent variable is measured for change
Theory
- A theory is a broad explanation supporting many hypotheses
Scientific Method
- The scientific method is systematic process for investigating inquiries involving hypothesis testing, data gathering, analysis, and conclusion-drawing.
