The United States Environmental Protection Agency has determined that all four pesticides
could have negative health consequences to humans if applied at high concentrations and has
set a maximum application concentration of 500g/cm3. Based on the data in the graph, which
pesticide would be the most effective at that concentration? - ANSWERS-d
Other than potential negative health effects on humans, which of the following is a
disadvantage of using chemical pesticides to eliminate crop pests? - ANSWERS-Pesticides may
harm organisms other than the target crop pests through biomagnification in the food web.
The Chatham Island robin is a small endangered bird found in scrub forests off the coast of New
Zealand. The robin is preyed upon by introduced species such as cats and rats. In 1980, the
population decreased to only 5 individuals and every individual today is a descendant of a single
female. Which of the following is best illustrated in the decline of the Chatham Island robins? -
ANSWERS-Population bottleneck
Which of the following resources would most likely be mined from the plant remains buried in
eastern Montana during the Cretaceous? - ANSWERS-Fossil fuels such as coal
Which of the following statements best describes photochemical smog in large cities in the
United States? - ANSWERS-Photochemical smog causes negative human health impacts such as
eye and lung irritation.
The underlying subsoil of this biome is permafrost, which prevents both water draining through
and deep-rooted plants from growing. Additionally, there is very little precipitation per year. -
ANSWERS-tundra
, The thick forest of this biome tends to be well adapted to short growing seasons. - ANSWERS-
taiga
This biome has the highest net primary productivity, in part because of consistently warm
temperatures and abundant sunlight. - ANSWERS-tropical rainforest
This area has low water-flow velocities because flowing water forms a reservoir that can be
used for hydroelectric power generation or recreation. - ANSWERS-d
This location is most likely to have thermal pollution as a result of electricity generation. -
ANSWERS-c
This area is likely to have impervious surfaces that increase runoff to streams during a rain event
and can contribute to the heat island effect. - ANSWERS-a
This area is most susceptible to erosion, leading to increased suspended solids and increased
turbidity downstream. - ANSWERS-b
Chemical compound responsible for ocean acidification in the open oceans of the world -
ANSWERS-carbon dioxide
Chemical compound that leads to formation of photochemical smog in the troposphere when it
reacts with other compounds in the presence of sunlight - ANSWERS-Nitrogen oxides
Chemical compound that can cause algal blooms and cultural eutrophication in streams -
ANSWERS-Nitrates
Chemical compound banned in most countries because of link to stratospheric ozone depletion
- ANSWERS-CFCs
