100
When the last individual organism of a species dies
What is extinction?
100
The process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations
What is natural selection?
100
Differences among the genes of members of the same species. A benefit of sexual reproduction.
What is genetic variation?
100
The first step of the Scientific Method.
What is the question or problem?
100
An explanation of why or how things happen in nature. Usually not mathematical. Supported by large amounts of evidence.
What is Scientific Theory?
200
All the fossils ever discovered on Earth
What is fossil record?
200
A slight difference in the appearance of individual members of a species
What is variation?
200
A body part that is similar in structure and position to the body part of another organism, though it has a different function
What are homologous structures?
200
After you research and read, you move on to this step of the Scientific Method.
What is form a hypothesis?
200
A description of a specific relationship under given conditions in the natural world. Tells us WHAT happens.
What is Scientific Law?
300
a fossil copy of an organism in a rock
What is a cast?
300
A characteristic of a species that enables the species to survive in its environment
What is adaptation?
300
A body part that performs a similar function to the body part of another organism, though it differs in structure
What are analogous structures?
300
The arguably favorite step of the Scientific Method. Usually takes place in a lab.
What is experimentation?
300
The _____ of Gravity is about the attractive force between all objects that have mass. (Theory or Law)
On Earth, acceleration is 9.8m/s/s.
What is Law?
400
The preserved evidence of the activity of an organism
What is a trace fossil?
400
The breeding of organisms for desired characteristics
What is selective breeding or artificial selection?
400
The study of similarities and differences among structures of living species
What is comparative anatomy?
400
After your experiment, the part of the scientific method where you classify information.
What is Data Analysis/ Analyze?
400
Atomic _______ states that all matter is composed of atoms that have a nucleus and electrons. (Theory or Law)
What is Theory?
500
The change over time in populations of related organisms
What is biological evolution?
500
Something from which two or more creatures develop that goes back more than several generations
What is a common ancestor?
500
A body part that has lost its original function through evolution.
What is a vestigial structure?
500
The final step of the scientific method. You use reasoning to make inferences and decide if your hypothesis is supported.
What is conclusion/ Draw a conclusion?
500
The naturalist who developed the theory of evolution by natural selection.
