Life
This is the basic structural and functional unit of life.
What is a cell?
The name of the islands where Darwin studied and gathered his evidence for natural selection.
What are the Galapagos Islands?
This is the most abundant gas in Earth's atmosphere.
What is nitrogen?
The three types of rock.
What are igneous, sedimentary, and metamorphic?
This variable is changed or manipulated by the experimenter.
What is the independent variable?
This molecule contains the genetic information that controls the development and function of an organism.
What is DNA?
When the environment presents conditions to an organism such that the organism survives or does not survive.
What is natural selection?
The process responsible for the gradual accumulation of oxygen in the atmosphere.
What is photosynthesis?
Water when it is in a gaseous state.
What is water vapor?
Data that can be measured as an amount.
What is quantitative data?
These single-celled organisms have neither distinct nuclei nor specialized organelles.
What are prokaryotes?
A change in an organism that can be physical, or otherwise, that is due to an internal change in that organism.
What is a mutation?
The natural light display that occurs when charged particles from the sun collide with gases in Earth's upper atmosphere.
What is the Aurora Borealis?
The two main processes through which the water and rock cycles interact.
What are weathering and erosion?
The process of drawing conclusions based on evidence and reasoning.
What is an inference?
These four criteria must be met in order for an organism to be considered alive.
What are the ability to reproduce, to demonstrate growth and repair, to metabolize, and to respond to external stimuli?
An organism that existed in the past and is shared by two or more different lineages of species.
What is a common ancestor?
The prevailing winds that blow in the middle latitudes.
What are the westerlies?
The exchange of oxygen and carbon dioxide between living cells and their environment.
What is respiration?
A specific statement about what is expected to happen in an experiment.
What is a prediction?
These three structures are unique to plant cells; helping to provide support and enable photosynthesis.
What are chloroplasts, the cell wall, and the large central vacuole?
The hypothetical single-celled organism that is considered the ancestor of all life on Earth.
Who is LUCA?
This forms when nitrogen oxides and sulfur oxides combine with water in the air.
What is acid rain?
This occurs when water vapor freezes as it falls.
What is snow?
A study in which neither the participants nor the experimenters know who is receiving a particular treatment.
What is a double-blind experiment?
