what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

different species on different islands

all species on one of the islands

identical species on all the islands

the same species as North America

Which of the following is NOT a characteristic of a stable, non-evolving population?

there is no migration in or out of the population

there is no natural selection in the population

mating in the population is random

Claytonia virginica is a woodland sring herb with flowers that vary from white to pale pink to bright pin. Slugs prefer to eat pink-flowering over white-flowering plants (due to chemical differences between the two), and plants experiencing severe herbivory are more likely to die. The bees that pollinate this plant also prefer pink to white flowers, so that Claytonia with pink flowers have greater relative fruit set than Claytonia with white flowers. A researcher observes that the percentage of different flower colors remains stable in the study population from year to year. Given no other information, if the researcher removes all slugs from the study population, what do you expect to happen to the distribution of flower colors in the population over time?

The percentage of pink flowers should increase over time.

The percentage of white flowers should increase over time.

The distribution of flower colors should not change.

The distribution of flower colors should randomly fluctuate over time.

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 is a true statement about natural selection?

variation in a trait must exist in a population

Random alleles increase in frequency

acquired characteristics become more frequent

all organisms of the same species have the exact same DNA

Which of the following is an example of gene flow?

bees carry pollen from flower to flower allowing gametes of flowers to combine

A group of wolves move to an island via an ice bridge in the winter

Male whales divide territory and mate with females in their territory

In the Hardy-Weinberg theorem, p refers to what?

The frequency of the dominant allele.

The frequency of the homozygous genotype.

The frequency of the recessive allele.

The frequency of the homozygous dominant.

A farmer uses triazine herbicide to control pigweed in his field. For the first few years, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these explanations best explains what happened?

Triazine-resistant weeds were more likely to survive and reproduce.

The herbicide company lost its triazine formula and started selling poor-quality triazine.

Natural selection caused the pigweed to mutate, creating a new triazine-resistant species.

Triazine-resistant pigweed has less-efficient photosynthesis metabolism.

Of the following anatomical structures, which is homologous to the bones in the wing of a bird?

bones in the flipper of a whale

bony rays in the tail fin of a flying fish

bones in the hind limb of a kangaroo

chitinous struts in the wing of a butterfly

Within six months of effectively using methicillin to treat S. aureus infections in a community, all new infections were caused by MRSA (methicillin resistant SA). How can this result best be explained?

Some drug–resistant bacteria were present at the start of treatment, and natural selection increased their frequency.

The drug caused the S. aureus DNA to change.

A patient must have become infected with MRSA from another community.

What is a Vestigial Structure?

genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species

Structures that have a common function and suggest common ancestry

The traits of organisms that result from sharing a common ancestor: such traits often have similar embryological origins

Two organisms that are closely related would have

completely different DNA sequence

Natural selection could not occur without

competition for unlimited resources

Which of the following statements regarding speciation is false?

It explains how a common ancestor is converted into another species

It involves evolutionary branching events

It involves the genesis of new species from ancestral species

It evidences that evolution has happened and will continue to happen

Two organisms are of the same species if they _. Select 3

Share many morphological characteristics

Share many molecular (DNA, RNA, and protein) similarities

Why does geographic isolation result in speciation?

The populations are exposed to different selective pressures in different environments

The populations are exposed to different selective pressures within the same environment

The populations are exposed to the same selective pressures in different environments

The populations are exposed to the same selective pressures within the same environment
