The study of life
Biology
All the living organisms that inhabit an environment
control group
All the different populations that live together in an area
Community
Uncontrolled growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors.
Cancer
A group of similar species
Genus
Shape of DNA
double helix
arranged in an orderly way
organization
organism that obtains energy by eating both plants and animals
Omnivore
Largest number of individuals of a population that a environment can support
carrying capacity
a measure of the genetic variation among individuals in a population
genetic diversity
Organisms early pre birth stage of development
Embryo
single-stranded nucleic acid that contains the sugar ribose
RNA
International System of Units
SI
A close relationship between two species that benefits at least one of the species.
Symbiosis
movement of individuals out of an area
Emigration
explains how fast a given population grows
population growth rate
Programmed cell death
Apoptosis
Bead-like structure in eukaryotic chromatin, composed of a short length of DNA wrapped around a core of histone proteins
Nucleosome
A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
Scientific Method
Each step in a food chain or food web
trophic level
Species that normally live and thrive in a particular ecosystem
native species
Materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain
natural resources
a group of organisms in a classification system
Taxon
enzyme that links together the growing chain of RNA nucleotides during transcription using a DNA strand as a template
RNA polymerase
in an experiment, the group not exposed to the variable ; contrasts with the experimental group and serves as a comparison for evaluating the effect of the variable
control group
Consists of all life on Earth and all parts of the Earth in which life exists, including land, water, and the atmosphere.
Biosphere
gradual process of a species becoming extinct
background extinction
gradual change in living communities that follows a disturbance
ecological succession
Second main stage of the cell cycle during which the cell's replicated DNA divides and two genetically identical diploid daughter cells are produced.
Mitosis
DNA to mRNA
GTA ACG TAC
CAU UGC AUG
