Mutualism is when two species that interact very closely both reap a benefit from the arrangement. Which of the following is the organism that is a mutualistic relationship between alga and fungus?

Zooxanthellae
Rhizobium
Lichen
Coral polyps

Correct Answer

A. Lichen

Explanation

Lichen is the correct answer because it is a mutualistic relationship between an alga and a fungus. The alga provides food through photosynthesis, while the fungus provides a protective structure and absorbs water and nutrients for both organisms. This symbiotic relationship benefits both the alga and the fungus, making it an example of mutualism.

How are the four layers of the atmosphere determined?

By temperature
By chemical make up
By altitude
By latitude

Correct Answer

A. By temperature

Explanation

The four layers of the atmosphere are determined by temperature because as altitude increases, the temperature changes. The layers are divided based on these temperature variations. The first layer, the troposphere, is the lowest and has decreasing temperatures with altitude. The second layer, the stratosphere, has increasing temperatures due to the presence of the ozone layer. The third layer, the mesosphere, experiences decreasing temperatures again. Finally, the thermosphere, the outermost layer, has increasing temperatures due to the absorption of solar radiation. Therefore, temperature is the primary factor used to determine the layers of the atmosphere.

Which of the following is the top most layer of our atmosphere?

Troposphere
Mesosphere
Stratosphere
Thermosphere

Correct Answer

A. Thermosphere

Explanation

The thermosphere is the topmost layer of our atmosphere. It is located above the mesosphere and stratosphere. This layer is characterized by extremely high temperatures and contains ionized gases. It is also where the auroras occur due to the interaction of solar particles with the Earth's magnetic field. The thermosphere plays a crucial role in protecting the Earth from harmful radiation and is home to the International Space Station.

Which layer of our atmosphere has the ozone layer?

Troposphere
Mesosphere
Stratosphere
Thermosphere

Correct Answer

A. Stratosphere

Explanation

The ozone layer is located in the stratosphere. This layer is situated above the troposphere and below the mesosphere. The ozone layer plays a crucial role in protecting the Earth by absorbing harmful ultraviolet radiation from the sun.

It is critical you understand the role we play in the Carbon Cycle, Nitrogen Cycle and Sulfur Cycles for the AP Test and just understanding what is going on in the air around you. Read this section on page 419. Which of the following cycles contribute to acid rain?

Carbon
Nitrogen
Sulfur
Lead
Both sulfur and nitrogen
Bothlead and carbon

Correct Answer

A. Both sulfur and nitrogen

Explanation

Both sulfur and nitrogen cycles contribute to acid rain. Acid rain is formed when sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere from human activities such as burning fossil fuels. These gases react with water, oxygen, and other chemicals in the air to form sulfuric acid and nitric acid, which then fall to the ground as acid rain. Therefore, understanding the sulfur and nitrogen cycles is important in comprehending the causes and effects of acid rain.

We take for granted electricity. The electricity that we are using every day is produced by burning coal to turn a turbine. Burning coal is one of the worst human processes as far as our air quality goes. On page 421 it discusses the percentage of different polluants released from coal burning power plants. What percent of the mercury released by humans comes from coal burning power plants? when you purchase your first house make sure you know where the closest powerplant is and try to live upwind of it!!!!!!

33%
45%
50%
75%
90%

Correct Answer

A. 33%

Explanation

The correct answer is 33%. On page 421, it discusses the percentage of different pollutants released from coal-burning power plants, including mercury. It states that 33% of the mercury released by humans comes from coal-burning power plants. This indicates that coal-burning power plants are a significant source of mercury pollution.

Read the section on photocomeical and industrial smog. Fort Worth has a huge problem with photochemical smog. During which of the following months would this problem be the worst?

December
March
August
October

Correct Answer

A. August

Explanation

Photochemical smog is formed when sunlight reacts with pollutants like nitrogen oxides and volatile organic compounds. These pollutants are released from various sources such as vehicles, industries, and power plants. In Fort Worth, the problem with photochemical smog would be the worst in August. This is because August is typically a hot and sunny month, providing favorable conditions for the formation of photochemical smog. The intense sunlight and high temperatures accelerate the chemical reactions between pollutants, leading to the accumulation of smog in the atmosphere.

What gives photochemical smog that brownish haze (it is also sometimes called brown-air smog)?

Carbon dioxide
Mercury
Nitrogen dioxide
Sulfur dioxide

Correct Answer

A. Nitrogen dioxide

Explanation

Nitrogen dioxide is responsible for the brownish haze in photochemical smog. When sunlight reacts with nitrogen oxides and volatile organic compounds (VOCs) emitted from vehicles, power plants, and industrial processes, it leads to the formation of nitrogen dioxide. This brown-air smog is a result of the chemical reactions between nitrogen dioxide and other pollutants in the atmosphere, creating a mixture of harmful gases and particles that contribute to air pollution and respiratory issues.

Still in the smog section - According to a 1999 article in Geophysical Research Letters, if _____ million Chinese drivers drive cars by 2050 as projected, the resulting photochemical smog could cover the entire western Pacific in ozone, extending to the United States!! Only 38 years from now!

150
10
400
1,000
279

Correct Answer

A. 400

Explanation

If 400 million Chinese drivers drive cars by 2050 as projected, the resulting photochemical smog could cover the entire western Pacific in ozone, extending to the United States. This suggests that the increase in car emissions from a large number of drivers would contribute to the formation of smog and ozone pollution, which could have far-reaching effects on air quality and public health.

Which of the following can actually reduce air pollution?

Rain and snow
Temperature
Urban buildings
Mountains

Correct Answer

A. Rain and snow

Explanation

Rain and snow can actually reduce air pollution because they act as natural cleaners by washing away pollutants from the air. When rain or snow falls, it captures and removes particles and gases such as dust, pollen, and pollutants like sulfur dioxide and nitrogen oxides from the atmosphere. This process is known as wet deposition, and it helps to improve air quality by reducing the concentration of harmful substances in the air. Therefore, rain and snow are effective in reducing air pollution.

Read the section on inddor airpollution. Many people don't think about how this affects you, but the air in our houses is often times polluted - especially in those houses with an attached garage (the CO from the car in the garage seeps through the door jams and into your house!). Which of the following chemicals is a colorless radioactive gas that is a carcinogen - causing lung cancer.

Sulfur dioxide
Argon
Hydrogem
Radon

Correct Answer

A. Radon

Explanation

Exposure to radon, a colorless radioactive gas, is a significant concern for indoor air pollution. It is particularly prevalent in houses with attached garages, as carbon monoxide from cars can seep into the house through door jams. Radon is a known carcinogen and can cause lung cancer. Therefore, radon is the correct answer to the question.
