Biological Organization
What is the Study of Life called?
A proposed explanation for a set of observations.
Hypothesis
This branch of biology is responsible for naming and classifying species
Taxonomy
This is the structural and functional unit of life.
A cell
The bird species you looked at during your Battle of the Beaks activity
Finches
A group of the same species living in the same geographic area.
population
This type of data involves descriptive characteristics rather than numbers.
Qualitative
The broadest taxonomic classification for living organisms includes three of these.
Domains
Life is characterized by this highly organized structure.
This scientist developed the theory of evolution by natural selection.
Darwin
This level of biological organization consists of all living things in a particular area, along with the non-living components they interact with.
ecosystem
The variable that is manipulated in an experiment.
Independent Variable
This domain includes organisms with complex cells that contain nuclei.
Eukarya
The ability of organisms to change over time through adaptation to their environment.
Evolutionary adaptation (Natural Selection)
The process by which individuals with advantageous traits are more likely to survive and reproduce.
natural selection
In the hierarchy of biological organization, encompassing all ecosystems on Earth.
Biosphere
This is used as a comparison with your experimental group
control group
The four categories under the Domain Eukarya
protists, plantae, fungi, Animalia
result from the specific arrangement and interactions among component parts.
emergent properties
The gradual change in a population’s traits over time due to differential survival and reproduction.
evolution
These biological molecules make up the internal machinery of cells and carry out functions.
Organelles
This is the broader concept in science, supported by a large body of evidence and explaining diverse phenomena.
Scientific Theory
This difference between Archaea and Bacteria involves the number of RNA polymerases they possess.
Archaea have three RNA polymerases, while Bacteria have one
This property of life allows an organism to maintain a stable internal environment.
homeostasis
These traits increase the likelihood of an organism's survival and reproductive success in its environment.
