The graph below shows the experimental data from an investigation testing how carbon monoxide levels in the ambient air alter the amount of oxygen hemoglobin can carry. The experiment was performed with five different laboratory mice. Each mouse was kept in its own habitat under constant conditions of water, food, light, and temperature. Each mouse was exposed to a different concentration of carbon monoxide, and the oxygen saturation level of hemoglobin was measured.
Which of the following modifications would improve the validity of the investigation?

Determine the oxygen saturation at carbon monoxide levels higher than 80%

Compare the oxygen saturation of mice at rest to that of mice that are active

Perform the experiment on a larger sample size of mice

Add a different number of plants to each habitat to add oxygen to the setup

The graph below shows the experimental data from an investigation testing how carbon monoxide levels in the ambient air alter the amount of oxygen hemoglobin can carry. The experiment was performed with five different laboratory mice. Each mouse was kept in its own habitat under constant conditions of water, food, light, and temperature. Each mouse was exposed to a different concentration of carbon monoxide, and the oxygen saturation level of hemoglobin was measured.
Which of the following conclusions can be drawn from the investigation?

Carbon monoxide impairs the transport of oxygen in the bloodstream

Oxygen saturation prevents the body from absorbing carbon monoxide from the air

Carbon monoxide improves oxygen transport in mammals

Oxygen saturation enhances the uptake of carbon monoxide from the air

Particulates can be removed from smokestack emissions by which of the following methods?

Irradiation by UV light

Electrostatic precipitators

Catalytic converters

Exhaust-stream aeration

Which of the following would most likely neutralize the effect of acid rain on bodies of water, based on the composition of soils and bedrock in the region?

A valley that is frequently shrouded in fog

An area downwind of a coal-burning electrical plant

An open plain underlain by granite

A forest underlain by limestone

Bats use echolocation to find prey by emitting high-pitched bursts of sound and analyzing the reflection. Scientists studying a population of bats in a forest observed that their population size had declined in the years following the completion of a nearby highway.
Based on the information above, which of the following best explains how noise pollution from the highway has affected the size of the bat population?

The highway noise is producing sound waves that disrupt air flow, preventing the bats from flying at night

The highway noise is interfering with bats’ echolocation, preventing them from successfully locating and catching prey as they fly

The highway noise is attracting more bats to the forest, causing an increase in intraspecies competition

The highway noise is decreasing the bats’ echolocation, allowing them to catch more prey each night

Which of the following best describes a natural process that adds carbon dioxide to the atmosphere?

Carbon dioxide is released from the interior of Earth during volcanic eruptions

Deposition of sediments into ocean basins release carbon dioxide from rock

Plants excrete carbon dioxide during photosynthesis

Burial of dead plants and animals in swamps and bogs allows CO₂ to escape to the atmosphere

Which of the following is a problem that is associated with a thermal inversion?

A decrease in the release of carbon dioxide from warmer air temperatures at the Earth’s surface, which accelerates global climate change

A decrease in evaporation rates over the ocean, which increases potential for more severe thunderstorms and hurricanes

An increase in UVUV radiation reaching Earth’s surface, which can damage plant tissue and decrease crop yield

An increase in pollutants trapped at Earth’s surface, which increases the number of cases of human respiratory problems

Industrial scrubbers and electrostatic precipitators collect enormous amounts of particulate matter (coal ash) at coal-burning power plants. Which of the following best describes an environmental disadvantage of using industrial scrubbers and electrostatic precipitators for pollution abatement?

Coal ash contains toxic levels of several different pollutants, so when it is collected and stored long-term in coal ash ponds, there is increased risk of exposure to toxic metals

Coal ash is highly flammable, and it is very hazardous to ship the materials to hazardous waste landfills

Industrial scrubbers and electrostatic precipitators cannot remove fine particles like dust and smoke from the waste, so a secondary measure must be used

Industrial scrubbers and electrostatic precipitators are very costly to install and increase the cost of operating coal-burning power plants, leading to increased costs for consumers

Which of the following illustrates the reactants needed to form tropospheric ozone?

SO₂+H₂O

CO₂+H₂O+sunlight
