Question 60
The energy source that is presently used the most for transportation in the United States is
hydroelectric generators.
solar energy.
imported oil.
nuclear energy.
coal.
Question 61
What is the major advantage of sex?
because it s the fastest way to reproduce
because it leads to babies
because it s fun
because it produces genetic variation among offspring which aids in survival
because humans are inherently bad
Question 62
Stabilizing selection involves the processes in which
an intermediate phenotype is favored
gene flow is eliminated
simultaneous bottlenecks have eliminated any phenotypic variation
the mutation rate is extremely low
None of these are correct
Question 63
The Allee Effect describes a phenomenon where a fish population will go extinct even if fishing pressure is lifted.
True
False
Question 64
Which of the following describes resource partitioning?
A climax community is reached when no new niches are available.
Competitive exclusion results in the success of the superior species.
Two species can co-evolve to share the same niche.
Slight variations in niche allow similar species to coexist.
Differential resource utilization results in the decrease in species diversity.
Question 65
Which one of the following statements about the consequences of global warming is FALSE?
Global warming will cause an increase in the incidence of diseases caused by mosquitoes.
Rising sea levels will be a consequence of global warming.
The frequency of El Niño events may increase as a consequence of global warming.
The rate of global warming may be too great for populations to be able to adapt through natural selection.
Since most crop plants grow better at higher temperature and CO2 concentrations, the effect of global warming on agriculture is likely to be positive.
Question 66

American Humane Society
Animals Rights Society
American Broney Club
US Department of Ethics
Association of Animals in Entertainment
Question 67
Addition of a primary carnivore to an ecosystem can sometimes influence the whole ecosystem. This process is called
disruption.
species turnover.
a top-down effect.
a trophic cascade.
a bottom-up effect.
Question 68
The most successful animal group ever to live on Earth (most numerous and most diverse in terms of species) is the
humans.
reptiles.
vertebrates.
insects.
sponges.
Question 69
An unusual characteristic of exponential growth is that it can continue indefinitely.
True
False
hydroelectric generators.
solar energy.
imported oil.
nuclear energy.
coal.
