Any trace or remains of a once living organism that has been preserved by natural processes.
What is a fossil.

Slang term that describes how organisms that posses the best traits or adaptations for a particular environment are the ones that will successfully pass down their traits to their offspring.
What is "Survival of the Fittest"
100
The age of Earth
What is 4.6 billion years old.
100
A category used to measure a particular impact of a given region.
What is an indicator.

You design an experiment to test the effect of temperature on bacteria growth. Temperature is this part of experimental design.
What is the independent variable.

Humans and chimpanzees share 99% of the same DNA. This suggests what about the two species?
What is they share a common ancestor.

The climate of a certain area is cold, and snow is found on the ground most of the year. Equal numbers of two populations of rabbits are introduced into this climate by a group of scientists. One of the populations is brown and the other is white. Over several generations, this will happen.
What is most of the rabbits will turn white.

Major periods of geologic time have been divided up according to this phenomenon that has happened 5 times in Earth's history.
What is mass extinction.
200
This sphere of sustainability focuses on preserving natural habitats, eliminating pollutants, and creating habitats for native species.
What is environmental.

Whales, which are mammals, have vestigial hind limb bones. The presence of these bones provides evidence that whales evolved from what?
What is land mammals?
300
Walking sticks are insects that live on plants. In one walking stick species, the insects may have either a striped body or a body without stripes. In one region where these walking sticks live, the dominant vegetation is a plant with needle-like leaves that resemble the walking stick's striped body. What will happen if predators are preying on this population of walking sticks?
What is the striped ones will increase.
300
Species that used to be the same but can no longer reproduce viable offspring have gone through which biological phenomenon?
What is speciation?
300
The enrichment of an ecosystem with nutrients such as nitrogen and phosphorus.
What is eutrophication?
400
“I think that the puzzle was an ocean scene because my group viewed a whales head in their pieces.” The student is making this type of statement.
What is an inference.
400
Birds, butterflies, and bats all have a structure that allows them to fly, but the anatomy of those structures differs greatly. This is an example of which type of structure?
What is an analogous structure.
400
When carving a pumpkin you notice there are a lot of seeds. Which component of natural selection supports the reasoning for this abundance of seeds?
What is overproduction
400
Approximately how many mya did dinosaurs go extinct?
What is 65 mya.

This greenhouse gas is often used as an indicator to the impact of a good or service on the environment.
What is carbon dioxide.
500
An experiment was conducted to determine the effect of adding fertilizer on plant growth. Three tomato seeds were planted in each of two six-inch pots. All the pots contained identical soil and were given the same lighting, water, and temperature each day. Pot A received 10mg of fertilizer, pot B received 20 mg of fertilizer, and pot C received no fertilizer. At the end of four weeks, scientists recorded the height of the plants in each pot. This pot is the control group for this experiment.
What is pot C.
500
Whale fins and bat wings are anatomically similar. These are considered to be what kind of structures?
What is homologous
500
This component of natural selection is beneficial is sexually reproducing organisms due to its ability to proliferate beneficial traits and mutations.
What is variation.
500
A mountain range forms due to plates under the Earth's crust colliding together. A population of foxes is split by the mountains and eventually becomes 2 different species. This is an example of speciation due to what type of barrier?
What is geographic barrier.
500
This non-renewable source is causing greenhouse gas emissions to raise global temperatures. We use this to create energy for houses, factories, and vehicles.
What are fossil fuels.
