What are the three domains of life?
Bacteria, archaea, eukarya
correct the sequence of biological organization, from the simplest to the most complex?
(organ, cell, community, tissue, population)

The two main forms of cells are __________ cells.
prokaryotic and eukaryotic
Using models that represented camouflaged and non-camouflaged mice, Hoekstra and her students tested the hypothesis that coloration of beach and inland mice provides camouflage that protects them from predation.
Regardless of whether the models were placed in the beach or the inland habitat, the camouflaged model always acted as the __________ group.
control
A scientific theory is __________.
a well-supported concept that has broad explanatory power
With evolution as the core theme of biology, we can explain traits shared by organisms as evidence of __________ and traits that differ among organisms as evidence of __________.
descent from a common ancestor; adaptation through natural selection
Some properties and processes that are associated with life include all of the following except _____________.
energy
growth and development
order
reproduction
reductionism
reductionism
A nonlinear, realistic model of the scientific process is called the process of science. The core activity of this process is __________.
forming and testing hypotheses
Natural selection tends to act at which of the following levels?
population level
The concept of “descent with modification” was proposed by __________.
Charles Darwin
In the theme of biological organization, the approach called reductionism __________.
allows us to reduce complex systems to simpler components that are more manageable to study
A hypothesis must be testable and falsifiable to be scientifically valid. Being testable and falsifiable means that __________.
some conceivable observation or experiment could reveal whether a given hypothesis is incorrect
What is the appropriate term for an interacting group of individuals of a single type occupying a defined area?
Population
The fundamental organizing principle of biology and core theme is __________.
evolution
Which of the following observations and inferences led Charles Darwin to his theory of natural selection as a mechanism for evolution?
