Parents pass this structure to their offspring.
What is a chromosome?

Scientists study this in order to determine how different species have changed over time.
What is the fossil record?
100
A population of rabbits living in a forest has both brown and white rabbits. Over time this environmental change results in the percentage of white rabbits increasing.
What is a snowy climate?

Variation is a foundational requirement for natural selection to occur. This increased diversity occurs due to mutations and this type of reproduction.
What is sexual reproduction?
200
A segment of DNA that provides instructions to make proteins is called this.
What is a gene?
200
This states that the lower layers are the oldest layers and the top layers are the newest layers.
What is the Law of Superposition.

At one time peppered moths were primarily light in color with only a few dark colored ones. During the industrial revolution soot covered many of the trees and light peppered moths were eaten by predators. The dark moths increased in frequency because they could now blend in with the soot covered trees. This was due to this type of adaptation.
What is camouflage?

These creatures share similar bone structures but have different functions.
What is a homologous structure.

A species of mice show a complete dominance pattern. A black mouse (Bb) is crossed with a white mouse (bb). The percentage chance of their offspring being white is this.
What is 50%?

The fossil record spans millions of years and shows how organisms started as simple organisms and diversified and became more complex over time. This record is one of the foundational pieces of evidence for this scientific theory.
What is evolution?

Below is a graph what happened to the running speed of a population of gazelle after a faster predator was introduced. Their speed could be said to have done this.
What is increase?

Courting dances and fancy plumage are used to attract mates for the purpose of reproduction. This form of natural selection is when the female of the species chooses what genetics is passed down.
What is sexual selection?
300
Wisdom teeth in humans, pelvic bones in whales, wings on the ostriche are all examples of these types of structures.
What are vestigial structures?
400
Bacteria reproduce through asexual reproduction. Many bacteria species have become antibiotic resistant. This can be attributed to the fact that its DNA often does this frequently.
What is a mutation?
400
A species of flowers shows an incomplete dominance pattern. Two pink flowers (RW) are crossed. These possible color offspring could be produced.
What is red, pink, and white?

Strawberries, bermuda grass, creeping Charlie all use these horizontal stems that grow along the soil surface, rooting at intervals to create new "clone" plants.
What are runners?

Birds eat berries in order to gain nutrients. The plant that provides the berries also is benefited by increasing the chances of seed germination which subsequently increases the chances of successful _____________.
What is reproduction?
400
This is a type of selection that is determined by human choice rather than something natural in the environment. For example, many fruits have been selected to be bigger and/or sweeter over time.
What is selective breeding?
500
Consider a population of finches living on an isolated island. If a drastic shift in the environment were to occur, this feature of the populations genetics would be necessary for the species to adapt to this change.
What is variation (diversity)?
500
The miohippus and merychippus fossils show the 'between' phases between the multi-toed dawn horse and the modern horse with hooves. These middle fossils are called this.
What are transitional fossils?
