Biology |
The study of life |
|
|
Organism |
It is anything that is made up of one or more cells, displays organization, grows & develops, reproduces, responds to stimuli, requires energy, maintains homeostasis, & develop adaptations over time. |
|
|
Organization |
Living things display this, which means that they're arranged in an orderly way. |
|
|
Growth |
The addition of mass to an organism, the formation of new cells and new structures. |
|
|
Development |
The process of natural changes that takes plaxce during the life of an organism. |
|
|
Reproduction |
The production of offspring. |
|
|
Species |
A group of organisms that can breed with one another and produce fertile offspring. |
|
|
Stimulus |
Anything that is part of an environment and causes a reaction
|
|
|
Response |
A reaction to a stimulus. |
|
|
Homeostasis |
Regulation of an organism's internal conditions to maintain life. |
|
|
Adaptation |
Any inherited characteristic that results from changes to a species over time. |
|
|
Phylogeny |
The evolutionary history of a species. |
|
|
Characters |
Inherited features that vary among species. |
|
|
Molecular Clock |
A model that is used to compare DNA sequences from two different species to estimate how long the species have been evolving since they diverged from a common ancestor. |
|
|
Cladistics |
A method that classifies organisms according to the order that they diverged from common ancestor. |
|
|
Cladogram |
A branching diagram tat represents the proposed phylogeny of a species or a group. |
|
|
Theory |
an explanation of a natural phenomenon supported by many observations and experiments over time.
|
|
|
Science |
is a body of knowledge based on the study of the natural world.
|
|
|
Law |
describes relationships under certain conditions in nature.
|
|
|
Peer review |
is a process by which the procedures and results of an experiment are evaluated by other scientists who are in the same field or who are conducting similar research.
|
|
|
Ethics |
which is a set of moral principles or values.
|
|
|
Observation |
direct method of gathering information in an orderly way.
|
|
|
Inferences |
The process of combining what you know with what you have learned to draw logical conclusions is called inferring; the conclusions themselves.
|
|
|
Scientific Method |
The scientific method is a way to ask and answer scientific questions by making observations and doing experiments.
|
|
|
Hypothesis |
is a testable explanation of a situation.
|
|
|
Experiment |
An experiment is a procedure carried out to verify, refute, or establish the validity of a hypothesis.
|
|
|
Control Group |
in an experiment is used for comparison.
|
|
|
experimental group |
is the group exposed to the factor being tested.
|
|
|
Independent variable |
the group exposed to the factor being tested. The kittiwakes getting the supplemental feedings were the experimental group.
|
|
|
Dependent variable |
variable. During an experiment, scientists measure a second factor.
|
|
|
Constant |
is a factor that remains fixed during an experiment while the independent and dependent variables change.
|
|
|
Data |
information gained from observations.
|
|
|
Metric System |
uses units with divisions that are powers of ten.
|
|
|
SI |
The system is called the International System of Units
