Biology
The scientific study of life
Cell
Basic unit of all living things
Levels of Biological Organization
Atom, Molecule, cell, tissue, organ, organic system, organism, population, community,
ecosystem, biosphere
Emergent Properties
Characteristics of life: organization, metabolism, homeostasis, response, reproduction and
development, adaptation
Energy
The ability to do work
TMetabolism
All the chemical reactions that occur in a cell
Photosynthesis
Process that converts solar energy into chemical energy of carbohydrates
Homeostasis
The maintenance of internal conditions within certain boundaries. Stability
Adaptation
Any modification that makes an organism better able to function in a particular environment
Evolution
The change in population of organisms over time to become more suited to the environment
Genes
Are passed down to the next generation. They determine characteristics of organisms and are
composed of DNA

Taxonomy
The branch of biology that identifies names and classifies organisms
Systematics
The study of evolutionary relationships between organisms
Classification Catagories for Organizing Diversity or Taxa....From most inckusive to least
inclusive
Domain, kingdom, phylum, class, order, family, genus, species
What are the Domains
Archaea, Bacteria, and Eukarya
What is the major difference between prokaryotes and eukaryotes?
Prokaryotes do not have a nucleus, eukaryotes do have a nucleus
What is the main difference between Archaea and Bacteria?
Archaea can live anywhere including harsh environments. Bacteria cannot live in harsh
environments.
What are the kingdoms of domain sunsets?
Protists, plants, animals, fungi
Binomial Nomenclature
Scientific name. Universal, Latin. Two-part name. First word is genus and is always capitalized.
Second word is species and always written in lowercase. Both words are italicized. Ex: Homo
sapiens (humans), Zea mays (corn)
Scientific method
The standard series of steps used in gaining knowledge for research
Steps of the scientific method
Observation, hypothesis, experiments and data collection, conclusion
Observation
Use senses to gather information

Hypothesis
A tentative explanation for what was observed, developed through inductive reasoning, and
testable
Experiment
A series of procedures designed to test a hypothesis
Experimental Design
The manner in which a scientist conducts an experiment
Experimental Variable
(Independent) it is the factor being tested
Test Group
Exposed to the experimental variable
Control Group
Is not exposed to the experimental variable
Data
Results of an experiment. Should be observable and objective
Conclusion
The data is analyzed and determines whether the hypothesis is supported or rejected. If it's
supported, findings are reported in scientific journals, peers review the findings, other scientists
test published findings
Scientific Theory
Concepts that are supported by a broad range of observations, experiments, and data
Scientific Principle/Law
Widely accepted theories with no serious challenges to validity
Matter
Anything that takes up space and has mass
