Two allopatric species of sparrows have very similar niches when compared to two sympatric species of sparrows. What would be a good explanation for this?

The allopatric species have no competition with one another so therefore can occupy similar niches

The sympatric species are usually mechanically isolated from one another

The sympatric species diverged from a common ancestor

The allopatric species are behaviorally isolated from one another

Which statement best describes the modes of selection depicted in the figure?

directional selection, favoring the average individual

stabilizing selection, changing the average color of the population over time

directional selection, changing the average age color of the population over time

disruptive selection, favoring the average individual

Which of the following statements is correct based on the information shown in this cladogram?

the turtle and the frog are more similar to each other than the turtle and the bass

frogs have existed for a longer time that bass

the frog is more closely related to the bass than to the leopard

Which of the following explains how natural selection causes a trait to become predominant in a population?

Individuals with traits that are favorable to the environment reproduce more.

Traits of an individual change in order to adapt to changes in enviornment.

organisms select which traits they wish to inherit

A horse and a donkey can successfully mate to produce offspring known as a mule. Mules are sterile . Would mules be classified as a species?

No, due to their inability to reproduce successfully.

Yes, mules have enough of their own traits to be considered a species.

Yes, the fact that have different number of chromosomes makes them a different species

No, mules are too similar to the parent species

All of the following should be used to construct evolutionary trees EXCEPT

morphological similarities and differences

Two allopatric species of sparrows have very similar niches when compared to two sympatric species of sparrows. What would be a good explanation for this?

The allopatric species have no competition with one another so therefore can occupy similar niches

The sympatric species are usually mechanically isolated from one another

The sympatric species diverged from a common ancestor

The allopatric species are behaviorally isolated from one another

Which of the following is an example of gene flow?

A young stallion is driven out of its herd by the alpha stallion and begins its own herd in another location

A subordinate wolf successfully challenges the alpha male and mates with pack females

A deer picks up spores from a plant as it grazes and deposits them next to that plant.

What explains the inclusion of rabbits?

they are the most recent ancestor of primates

they have a short generation time and are easy to study

they possess shared derived characteristics of the included species

A group of mice was released into a large field to which no other mice had access. Immediately after the release,a representative sample of the mice was captured, and the fur color of each individual in the sample was observed and recorded. There were 10% gray mice, 80% brown mice and 10% black mice. The mice were then returned to the field. After twenty years, another representative sample of the mice was captured, and the fur color of each individual in the sample was again recorded. This time there were 60% gray mice, 30% brown mice and 10% black mice

The field was composed primarily of light-colored soil and little vegetation, affording gray mice protection from predators.Increasing the number of mice which have the allele for gray fur

The allele for gray fur color is unstable

Natural selection led to increased mating frequency of black and brown versus gray and brown

The gray mice were hardest to capture and so were underrepresented in the twenty-year sample

Which of the following is NOT an observation upon which natural selection is based?

The size of populations fluctuates over time.

There is heritable variation among individuals.

Poorly adapted individuals leave less offspring.

Individuals whose inherited characteristics best fit them to the environment will leave more offspring.

A biologist spent many years researching the rate of evolutionary change in the pink salmon population of the Pacific Northwest. It was determined that the average size (both length and mass) of the salmon decreased dramatically between 1945 and 1970. During this time fisherman were paid by the pound and there was an increase in the use of gill netting to harvest fish. Which of the following best describes the mechanism behind the change in size in the pink salmon population?

A change in gene frequencies in the salmon population due to selective pressure from fishing.

The formation of two new salmon species from a single parent species

A new allele appearing in the salmon population as a result of mutation

The achievement of dynamic equilibrium in the salmon population as a result of homeostasis.

In 1977, Mr. Smith used the pesticide malathion to protect his orange groves from fruit fly damage. He sprayed his trees with malathion again in 1978. In 1979, Mr. Smith used twice the dose of malathion to protect his crop. Which of the following best explains the data graphed?

The fruit flies who were immune to malathion survived the first application in 1977 and produced more offspring than those who did not have this genetic variation

The plants developed a resistance to the malathion in 1978, rendering it less effective which made those resistant plant more fit.

The fruit flies develop resistance to malathion through a random mutation in 1978

The pesticide used by Mr. Smith in 1978 and 1979 was not as potent as that used in 1977

Your friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks” Which statement is the best response to correct your friend’s misconception?

Characteristics acquired during an organism's life are generally not passed on through genes to its offspring.

Overproduction of offspring leads to a struggle for survival.

Only favorable adaptations have survival value.

Disuse of an organ may lead to its eventual disappearance.
