Refer to the figure.
The three factors shown in the graphs provide evidence supporting the hypothesis that CO
2
emissions by humans are associated with rising atmospheric CO
2
and temperature. The graphs support the hypothesis because all three factors are
measured within the atmosphere.
correct
incorrect
measured indirectly.
correct
incorrect
rising at approximately the same rate.
correct

rising at very slight, insignificant rates.

Which of these examples represents an impact of climate change on a living system?
The hottest year so far in the historical record was 2016.
correct
incorrect
Arctic sea ice reached a record low in 2017.
correct
incorrect
Extreme weather events such as hurricanes and snowstorms are increasing.
correct

At atmospheric temperatures rise, concurrent rises occur in ocean temperatures. In addition, excess atmospheric CO
2
enters the oceans and dissolves to form carbonic acid, which increases ocean acidity. As these processes continue, what is the likely future impact on the world’s coral reefs?
No likely impact; these processes do not impact corals.
correct
incorrect
More reefs will die due to bleaching as temperature and acidity rise.
correct
incorrect
Reefs will die off in the short term but will recover and adapt to the new acidity levels.
correct
incorrect
Reef health will improve, and growth will increase as temperature and acidity increase.

Two conservationists disagree over whether the number given by CITES for the total number of a species of frog exported from a South American rain forest represent an overestimate or an underestimate. Which of these situations is likely to result in an
underestimate
?
Some frogs have been re-exported several times and were counted each time.
correct
incorrect
Poor identification has led to several species being combined in the count.
correct
incorrect
Counts were based on permits granted, but not all permit owners exported frogs.
correct
incorrect
The count included both whole frogs and frog legs; each single leg was counted as one frog.

A student is writing an essay trying to make a scientific argument that commercial whaling of all whale species should be banned. Which of these statements best supports her argument?
Northern right and blue whale populations are far below their original numbers.
correct
incorrect
Most whales are not currently on the endangered species list.
correct
incorrect
Several coastal countries hunt whales as part of their culture.
correct
incorrect
Numbers of most whale species have recovered since the 1986 whaling ban.

The black rat is one of the first invasive species. It originated in tropical Asia, reached Europe in the first century CE, and spread around the world, hiding on European ships. This animal became an invasive species through which of these methods or sources?
European colonization
correct

Accidental transport
correct

Biological control
correct

In Cuba, dogs are considered an invasive species. In Florida, 90 miles away, they are not. Why might dogs be more damaging to Cuban ecosystems than to Florida ecosystems?
Cuba is south of Florida; it is more tropical and its ecosystems more fragile.
correct
incorrect
Cuba is smaller than Florida; it has less room to maintain new species.
correct
incorrect
Cuba’s native species are trapped on an island and less adapted to withstand invaders.
correct
incorrect
Dogs are better able to survive in Cuba than in Florida, thus they pose a greater risk there.

correct
incorrect
Their ability to become toxic if allowed to grow wild

Scientists hope to decrease the incidence of white nose syndrome (WNS) in populations of bats in a fairly unpopulated region of the northeast United States. Which of these approaches would be most likely to result in decreasing WNS?
Capture the bats and bring all of them to live into a laboratory setting while treating WNS.
correct
incorrect
Close more isolated bat caves, forcing all bats to roost in more accessible caves, where they can be more easily treated.
correct
incorrect
Bring as many bats as possible into zoos and wildlife refuges, where they will have more contact with other species and less contact with other bats.
correct
incorrect
Prevent tourists from entering bat caves, and allow in only scientists with sterilized clothes and equipment.
correct
incorrect
