Question 1 of 27

1

The theory of natural selection states that:

Select one of the following:

individuals that live the longest are best adapted and selected for survival in the next
generation.

Question 2 of 27

1

Question 5 of 27

1

The long neck of a giraffe has developed over a long period of time because giraffes
have needed to stretch their necks to reach food high in trees, and that quality has been
passed on through the generations. This view of evolution would correspond with the
ideas of:

Jean-Baptiste de Lamarck.
Charles Lyell.
Georges Cuvier.

Explanation

Question 6 of 27

1

the chemicals mutate.

Explanation

Question 7 of 27

1

A population is:

Select one of the following:

a group of organisms that can successfully interbreed in nature but do not interbreed
with other such groups
all the members of a species that live in a defined geographic region at the same time.
all the different species that live in a defined geographic area at the same time.
a group of different species that share common features.

Explanation

Question 8 of 27

1

The gene pool for a particular gene would include:

Select one of the following:

the sum of all the alleles for all the traits in the population.
all the alleles for a given trait in a particular individual organism of the population.
the sum of all the phenotypes in the population.
all the alleles for a particular gene in all the individuals in the population.

Explanation

Question 9 of 27

1

What is the difference between microevolution and macroevolution?

Select one of the following:

Microevolution is hypothetical because changes are too small to be observed, whereas
macroevolution is detectable
Microevolution deals with microscopic organisms, whereas macroevolution deals with
larger ones.
Microevolution describes what happens in small populations, whereas macroevolution
deals with large populations
Microevolution describes changes within a population over a short period of time,
whereas macroevolution describes larger changes such as the formation of new species
over longer periods of time.

Explanation

what phenomenon will probably decrease?

Select one of the following:

mutation

immigration
founder effect and genetic drift

Explanation

Question 11 of 27

1

Shrews have been documented to travel across frozen lakes and establish populations
on previously uninhabited islands; thus, the shrews have a limited gene pool. If this
limited gene pool has allele frequencies that are very different from the allele frequencies
found in the original population, then this would be an example of:

Select one of the following:

natural selection
population bottleneck
divergent evolution
founder effect

Explanation

Question 12 of 27

1

known as:

Select one of the following:

microevolution
adaptation

occur is:

Select one of the following:

allopatric
temporal
behavioral
sympatric

Explanation

Question 17 of 27

1

genetic divergence occurs that prevents them from breeding with other populations. What
has happened?

Select one of the following:

speciation
formation of genetic drifts
directional selection
mechanical incompatibility

Explanation

Question 18 of 27

1

The many species of tree frogs that inhabit forests in the eastern United States
maintain their genetic isolation from other species by several mechanisms, including
"singing" slightly different songs. Which type of isolating mechanism does this
represent?

Select one of the following:

temporal isolation
behavioral isolation
ecological isolation
mechanical isolation

Explanation

Question 19 of 27

1

Pollen of one plant species will not germinate on the flower of another species. This
is an example of:

Select one of the following:

temporal isolation.
hybrid inviability
hybrid infertility.
gametic isolation

Explanation

Question 20 of 27

what has occurred?

Select one of the following:

divergent speciation
polyploidy

Select one of the following:

species
family
order
genus

Explanation

Question 22 of 27

1

These are produced by:

Select one of the following:

convergent evolution.
divergent evolution.
reproductive isolation.
adaptive radiation.

Explanation

Question 23 of 27

notice that the culture is producing methane. In which group would you place this
organism?
