Which of the following best shows the process of evolution?

A population of mosquitoes develops resistance to a pesticide.

A lizard's color becomes brown as it sits on a log

What is the best definition of animal adaptation?

Characteristics that help animals survive.

Characteristics of an animal's habitat.

The theory of evolution by natural selection means that what is changing over time?

The inherited traits of a population.

The acquired traits of a population.

Natural selection is the process by which

organisms with traits well-suited to their environment reproduce at a greater rate than less well-adapted organisms in the same environment

change occurs in the genetic characteristics of individuals that live together in an environment from one generation to another

use and disuse of a characteristic leads to evolutionary change

baseball players pass on the trait for strong arm muscles to children

According to Darwin’s theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to the

possession of inherited adaptations that maximize fitness.

possession of adaptations developed through use.

lack of competition within the species.

choices made by plant and animal breeders.

An endemic species is

native and found only in a limited area

exotic and found only in certain regions

Why are sea otters so crucial to an ecosystem?

What is true about endemic species?

They are more vulnerable to extinction

They are less vulnerable to extinction

Which of the following statements is true?

Volcanoes creating igneous rock formations lay based for primary succession to take place

Primary succession is followed by secondary succession

Primary succession occurs over a shorter time span

Forest fires and hurricanes lead to primary succession because a soil base still exists

What is artificial selection?

When humans selectively breed organisms together to select for traits most desirable to us

When new organisms migrate into an area and introduce new genes

When organisms are separated from other members of their population due to new geographic barriers

What is the founder effect?

When a small population breaks off of an existing population

When survivors of a natural disaster repopulate the environment

Changes in the genetic makeup of a population over time

The migration of organisms between two similar populations

The graph shows the change in percentages of grey prey in a population over time. What conclusion can be drawn from the graph?

Grey prey had a high fitness in the mountain rock environment

Grey prey had a high fitness in the desert sand environment

There was an increase in mutations in the population

There was an increase in variation in the population

Both moths pictured are part of the same species. Which moth has higher fitness in this environment and why?

The dark colored moth because it blends in

The light colored moth because it stands out

The light colored moth because it is bigger

The dark colored moth because they are more intelligent
