• adaption

Multiple Choice

Which of the following is NOT an example of natural selection?

• People selectively breeding hamsters for size.

• Insect populations developing resistance to certain pesticides.

• Bacteria becoming resistant to antibiotics.

Multiple Select

How does Pangaea support the Theory of Evolution? Select all that apply

• It provides an explanation for why similar fossils are found on different continents

• The movement of continents provides an example of a big change in environment that would cause evolutionary pressures that would drive species to evolve

• It explains how the planet became warmer over the years

• It provides evidence that continents are growing in size slowly

Multiple Choice

Which best describes the phrase survival of the fittest?

• strongest in a population are most successful

• those that can survive and reproduce are most successful

• fastest in a population are most successful

• those that can live the longest are most successful

Multiple Choice

_______selection is when humans choose traits of an organism like breeding dogs

• Artificial

• Natural

• Pseudo

Multiple Choice

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment

• Dark moth

• Both will be equally successful

• Light moth

• Neither will be successfu

Multiple Choice

Pistol shrimp have protective eye pocket tissue, but some shrimp do not have this trait. What role will natural selection most likely play in this trait within the population?

• the frequency of the allele for eye pocket tissue will increase in the population because it is beneficial

• the frequency of the allele for eye pocket tissue will decrease in the population because it is beneficial

• the frequency of the allele for eye pocket tissue will not change since only a few individuals do not have it

• Natural selection will lead to the extinction of the shrimp without eye pocket tissue

Multiple Choice

The type of selection in which individuals of average size have greater fitness than small or large individuals have is called

• stabilizing selection.

• directional selection.

• disruptive selection.

Multiple Choice

A population of rabbits has three fur colors: white, gray, and black. After volcanic activity, the terrain changed and now the rabbits now live on white rocks and black rocks. What type of selection is likely to occur?

• Directional selection

• Stabilizing selection

• Disruptive selection

Multiple Choice

Long necks make it easier for giraffes to reach leaves high on trees, while also making them better fighters in neck wrestling contests. In both cases, which kind of selection appears to have made giraffes the long-neck creatures they are today?

• Directional Selection

• Stabilizing selection

• Disruptive selection
