_____ are close interactions between species that have evolved over
long periods of time. When these interactions enhance the reproduction
and population growth of both species, they are called _____.
A. Symbioses; mutualisms
B. Mutualisms; symbioses
C. Symbioses; antagonisms

1. Glacier Bay in Alaska is a fjord whose lowlands were covered by glacial
ice until around 230 years ago. As the glacier retreated, glacial till was
exposed to plant colonization; remarkably (and fortunately for
generations of ecologists), the location of the tip of the retreating glacier
has been frequently documented since the late 1700's. This means that
scientists have been able to develop a detailed timeline of the changes in
the plant community, or _____ in Glacier Bay over time.
A.ecological succession
B. niche diversification
C. niche divergence
,D. competitive exclusion
E. none of these - correct answer- A.ecological succession
1. The peppered moth provides a well-known example of natural
selection. The light- colored form of the moth was predominant in
England before the industrial revolution. In the mid-nineteenth century,
a dark-colored form appeared. The difference is produced by a dominant
allele of one gene. By about 1900, approximately 90% of the moths
around industrial areas were dark colored, whereas light-colored moths
were still abundant elsewhere. Apparently, birds could readily find the
light moths against the soot-darkened background in industrial areas
and therefore were eating more light moths. Recently, use of cleaner
fuels has greatly reduced soot in the landscape, and the dark-colored
moths have been disappearing. Should the two forms of moths be
considered separate species?
A. No
B. Yes, because natural selection has affected the frequency of the two
different forms.
C. Yes, because they have completely different color - correct answer-
No
10. If you stand at the equator and throw a ball north (really hard, like
Superman), which direction will it deflect relative to where you were
standing when you threw the ball?
A. The ball will deflect east.
B. The ball will deflect west.
,C. The ball will move at the same speed as you and come right back to
you.
D. None of the other answer options is correct. - correct answer- A.
The ball will deflect east.
11. There are many climatological factors that contribute to high levels
of rainfall at the equator. Which of the following is not a reason for high
rainfall at the equator?
A. As warm air rises, it cools and water condenses to form rain.
B. There are high levels of solar radiation at the equator.
C. Temperatures are relatively constant. - correct answer- C.
Temperatures are relatively constant.
15. Which latitude typically receives more rainfall than any other
latitude?
A. 0 degrees
B. 30 degrees
C. 60 degrees
D. 90 degrees - correct answer- A. 0 degrees
2. According to Niko Tinbergen, which of the following defines―and
helps researchers understand―an animal's behavior?
A. adaptive function, causation, development, and evolutionary history
B. adaptive function, causation, and development
, C. adaptive function, development, and evolutionary history
D. causation, development, and evolutionary history
E. evolutionary history - correct answer- A. adaptive function,
causation, development, and evolutionary history
3. Cultural traits are transmitted horizontally (within generations) and
vertically (between generations) through learning. Which of the
examples below shows the horizontal transmission of culture?
A. A mother teaches her son how to ride a bike.
B. A female chimpanzee teaches her offspring to capture termites using
a stick.
C. A son inherits the recessive form of a gene from his father.
D. A teenager teaches her brother how to text.
E. None of a-d is an example of horizontal transmission of culture. -
correct answer- D. A teenager teaches her brother how to text.
4. You find that a wild population of antelope is not in Hardy-Weinberg
Equilibrium. From this information alone, can you determine the
mechanism of evolution operating on the population?
A. yes
B. no - correct answer- B) No
5. A population with a novel adaptation has evolved that adaptation.
A. True
