Chapter One Flashcards
List the 10 Biological Hierarchy
- The Biosphere
- Ecosystem
- Communities
- Population
- Organisms
- Organ and Organ Systems
- Tissues
- Cells
- Organelles
- Molecules (Atoms)
Emergent Properties
Results from the arrangement and interaction of parts within a system.
(Ex: Functioning Bike emerges only when all of the necessary parts connect in the correct way)
Reductionism
The reduction f complex systems to simpler components that are more manageable to study
Systems Biology
Constructs models for the dynamic behavior of whole biological System
Chromosomes
contain most of a cell’s genetic material in the form of DNA
Genes
are the units of inheritance that transmit information from parents to offspring
Gene Expression
is the process of converting information from gene to cellular product
Genome
Organisms entire set of genetic instructions
Negative Feedback
means that as more of a product accumulates, the process that creates it slows and less of the product is produced.
Positive Feedback
means that as more of a product accumulates, the process that creates it, speeds up and more of the product is produced.
Taxonomy
the branch of biology that names and classifies species into groups of increasing breadth
The Units of Classification
- Domain
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
The Three Domains of Life
- Archae
- Eukarya
- Bacteria
Eukarya
Includes three multicellular Kingdoms:
- Plants
- Fungi
- Animals
Theory
- Broader in scope than a hypothesis
- General, and can lead to new testable hyptheses
- Supported by a large body of evidence in comparison to a hypothesis
