Study Notes
Introduction to Bio 111
- The course covers evolution, biological themes, and scientific inquiry
- The course is taught by Professor Julia E. Porado MS CT(ASCP)
Agenda for Chapter 1
- Cell Theory
- Requirements of Life
- Levels of Biological Organization
- Principles of Evolution
- Scientific Method
Properties of Life
- Biology is the scientific study of life
- Properties of life include:
- Order (structure)
- Evolutionary adaptation
- Regulation
- Energy processing
- Growth and development
- Response to the environment
- Reproduction
Order: Structure
- Focused on the ordered structure of organisms, like a sunflower
Evolutionary Adaptation
- Focuses on the adaptations of organisms, like the example of a squid
Regulation
- Covers the circulatory systems and their regulation, via images of arteries and veins
Energy Processing
- Includes images of a baby eating to illustrate this function
Growth and Development
- Shows images of a plant's growth from seedling to ripening stage
Response to the Environment
- Illustrates a plant responding to its environment, via a Venus flytrap
Reproduction
- Shows an example of a mother cat and kitten to illustrate reproduction
Exploring Levels of Biological Organization
- Discusses the biosphere, ecosystems, communities, populations, organisms, organs, tissues, and cells, and organelles
The Biosphere
- All life on Earth and where life exists
Ecosystems
- All living things in a specific area, plus the non-living components
Communities
- The array of species in a particular ecosystem
Populations
- All individuals of a species living in a specific area able to interbreed
Organism
- An individual living thing
Organs
- A body part made up of multiple tissues with a specific function
Tissues
- A group of cells working together for a specific function
Cells
- Life's fundamental unit, containing organelles, and either single-celled organisms or part of a larger multicellular organism
Organelles
- The various functional components of a cell, like the nucleus and mitochondria
Molecules
- Chemical structures of two or more atoms
- Building blocks of life
Systems Biology
- Analyzing a biological system by examining interactions between its parts
Structure and Function
- A fundamental principle of biology
Cell Theory
- Living organisms are made of cells, the basic unit of life
- Eukaryotic cells contain membrane-bound organelles and a nucleus
- Prokaryotic cells lack a nucleus and membrane-bound organelles
- Diagram of both a eukaryotic and prokaryotic cell are shown
DNA: The Genetic Material
- Genes are the units of inheritance, located on chromosomes
- Transcription: DNA to RNA to protein
- DNA is a double helix of nucleotide chains - Base pairs: A-T, C-G
Genomics
- Large-scale analysis of the DNA sequences in an organism's genome
- Includes genomics, proteomics, and bioinformatics tools
Life's Needs
- Transfer and transformation of matter and energy
- Producers (photosynthesizers)
- Consumers
Energy Transformation Concepts
- Metabolism: chemical changes in a cell/organism enabling growth, reproduction and health
- Homeostasis: tendency towards equilibrium between interdependent elements, especially in physiology
Molecules: Interactions Within Organisms
- Feedback regulation: output regulates the process
- Example: blood glucose level regulates insulin secretion
Evolution: Unity and Diversity
- Biological change accumulating differences from ancestors
3 Domains of Life
- Bacteria and Archaea (prokaryotic)
- Eukarya (eukaryotic, including kingdoms Plantae, Fungi, Animalia, and Protists)
Charles Darwin
- Natural selection: higher proportion of favorable traits in a population over generations
- Organisms with traits that enhance survival are more likely to reproduce
Scientific Study
- Inquiry: search for information on natural phenomena
- Exploration and observation
- Data collection and analysis - Qualitative (descriptions) - Quantitative (measurements)
- Inductive reasoning: general conclusions from specific observations
Forming and Testing Hypotheses
- Hypothesis: testable explanation
- Deductive reasoning: specific results expected from general premises
- Experiment: a controlled scientific test
Variables and Controls
- Controlled experiments: compare an experimental group to a control group
- Variables: factors measured - Independent variable: manipulated factor - Dependent variable: measured factor affected by the independent variable - Example: radiation therapy study
Theory
- A comprehensive explanation with enough boardness to create hypotheses
Scientific Method
- A step-by-step process of scientific investigation starting by defining a question to investigate and ending with drawing conclusions
