Term
The Goals of Science
Definition
To provide natural explanations for things that occur in the natural world, and use those explanations to find patterns and answers to natural phenomena.
Term
Scientific Method
Definition
The process of making observations, inferences/questions, hypothesis, test experiment, compile and publish data.
Term
Theory
Definition
Something that has been proven and is generally accepted as fact. While in common culture we usually interpret it as a hunch.
Term
Bias
Definition
When the interest of one's own personal gain interferes with the data they are going to publish. (Kind of like conflict of interest)
Term
Definitions in SCIENCE
Definition
They may change due to new data coming up and contradicting our previous ideas.
Term
Science
Definition
The study of natural phenomena explained through natural explanations
Term
Characteristics of Life
Definition
1) Cellular 2) obtain and use energy 3) grow and develop 4) reproduce 5) respond to environment 6) adapt to environment
Term
Observation
Definition
An unbiased observation
Term
inference
Definition
an educated guess
Term
hypothesis
Definition
a scientific explanation for a set of observations that can be tested
Term
controlled experiment
Definition
an experiment in which only one variable is changed
Term
independent variable
Definition
a variable that is not effected by other variables
Term
dependent variable
Definition
a variable that depends on another
Term
Central themes of biology
Definition
Cellular basis of life; information and heredity; matter and energy; growth, development, and reproduction; homeostasis; evolution; structure and function; unity and diversity of life; independence in nature; science as a way of knowing
Term
control group
Definition
one group in a experimental set that is not exposed to any variables while the others are
Term
data
Definition
information gathered from an experiment
Term
yeast
Definition
a good model for experimentation because they display all the characteristics of life but are abundant and require little matenance

Term
binomial nomenclature
Definition
the process of naming a species in a two part latin form
Term
genus
Definition
a group of similar species

Definition
Italicized, first word (Genus) capitalized, second word (species) not.
Term
systematics
Definition
organizing living things into biologically related groups
Term
taxon
Definition
groups created through systematics
Term
Scientific name vs. common name
Definition

family
Definition
a group of genera
Term

Term
Genus
Definition
the first part of a scientific name that relates animals to eachother
Term
definition of a species
Definition
difficult to pin down due to species changing a lot
Term
classification
Definition
has changed over the years due to us being able to compare DNA between species to get more specific biological relationships
Term
3 domains of life
Definition
Archaea, Bacteria, and Eukarya
Term
Six kingdoms of life
Definition
Archaebacteria: hot/harsh conditions, unicellular. Eubacteria: also complex and unicellular, but chemical make up is different; most common bacteria. Protista: anything that's not a Archaea, bacteria, plant, fungi, or animal; most are unicellular. Fungi: Most are multicellular, cannot make their own food. Plantae: Multicellular, complex;second largest kingdom. Animalia: largest kingdom, with 1 millions members; complex, heterotrophs.
