Scientists usually begin with this to start an experiment.
What is an observation?
100
"The subject smelled like vanilla" is an example of this observation.
What is a qualitative observation?
100
This is the study of living things.
What is biology?
100
This is a change in heritable traits in a population over generations.
What is evolution?
100
Who is the father of evolution?
Who is Darwin?
200
You change one of these within your test group.
What is an independent variable?
200
This is the part of the experiment that is affected by the independent variable and that is measured.
What is the dependent variable?
200
All living things are composed of these?
What are cells?
200
All of the individuals of the same species that live in a specific place is this.
What is a population?
200
What is a group of similar individuals that can naturally interbreed and produce fertile offspring
What is a species
300
You need one of these to compare your results to the test group.
What is a control group?
300
This is something that the experimenter changes in the experiment.
What is the independent variable?
300
This is the molecule of heredity in organisms.
What is DNA?
300
This is when humans choose which individuals will reproduce based on their traits
What is artificial selection?
300
What is fitness a measure of?
What are ability to survive and reproduce
400
This is an explanation that is based on substantial evidence from repeated experiments.
What is a theory?
400
"The mass of the product formed was 147.2 grams" is an example of this type of observation.
What is a quantitative observation?
400
This is the ability to maintain a stable internal condition.
What is homeostasis?
400
This is a process by which organisms better adapted to their environment are more likely to survive and reproduce.
What is natural selection?
400
When a horse and a donkey mate, they produce a mule. When tigers and lions mate they produce a liger. Mules and ligers are examples of what type of organism?
What is a hybrid?
500
This is a proposed explanation for an observable occurrence
What is a hypothesis?
500
Pluto no longer being considered a planet is an example of this criteria of science.
What is tentativeness?
500
This is the ability to do something in the future.
What is potential?
500
Who proposed the wrong mechanism for evolution where the traits used and developed by the individual are passed to their offspring?
Who is Lamarck?
500
This is when there is a physical change in the DNA that may or may not cause in traits.
