Chapter 1: Biology: Exploring Life
Biology: The study of life
Properties and processes associated with life
o Reproduction:
organisms can produce their own kind
o Growth and Development:
Inherited information encoded in DNA controls the pattern of growth and
development of all organisms
o Energy Processing:
Organisms take energy and use it to power all their activities
o Evolutionary Adaptation:
Evolution over countless generations as individuals with heritable traits
that are best suited to their environment have greater reproductive
success
o Regulation:
Organisms have regulatory mechanisms that maintain a beneficial
internal environment
o Response to the Environment:
All organisms respond to environmental stimuli
o Order:
Life is characterized by highly ordered structures
Biologists arrange the diversity of life into three domains
o Domain Bacteria
Bacteria
o Domain Archaea
Archaea
o Domain Eukarya
Protists (multiple kingdoms)
Kingdom Plantae
Kingdom Fungi
Kingdom Animalia
Hierarchy of Organization
1. Biosphere:
a. All the life on earth and the places where life exists
2. Ecosystems:
a. All the organisms in a particular area, as well as the physical components with
which life interacts such as soil, water, and light

3. Community:
a. All the organisms in an ecosystem
4. Population:
a. All the individuals of a particular species living in a community
5. Organism:
a. An individual living thing
6. Organ/Organ Systems:
a. Body parts that perform specific functions
7. Tissue:
a. A group of similar cells performing a specific function
8. Cell:
a. The fundamental structural and functional unit of life
9. Organelle:
a. A membrane enclosed functional structure in a cell
10. Molecule:
a. A chemical structure consisting of two or more units called atoms
The Process of Science
Science
o A way of knowing, an approach to understanding the natural world
Data
o Recorded observations, the evidence of which scientific inquiry is based
Qualitive: recorded descriptions
Quantitive: numerical measurements
Hypothesis
o A proposed explanation for a set of observations
o Leads to predictions that can be tested by making additional observations or
experiments
Experiment
o Scientific test, often carried out under controlled conditions
Theory
o Broader scope supported by a large usually growing body of evidence
o High degree of certainty
Controlled Experiments
Independent Variable
o The factor that is being manipulated by the research
Dependent Variable
o The measure used to judge the outcome of the experiment
Controlled Experiment
