Which part of solar energy is important in photosynthesis?

The visible spectrum of light

Hemlock trees support life of other organisms. Climate change has increased the rate of infection of Hemlocks with woolly adelgid. These kill the trees which decrease the habitat of animals and other insects. This is an example of how climate change impacts the

A(An) ______ represents the interactions of biological communities and the abiotic factors within the inhabited location.

ecosystem

Since the 1950s, there has been a steady increase in the levels of atmospheric CO2 as a result of

increased human activity

Over the past several decades, the overall trend for earth's temperatures has been

increases in overall global temperatures at an accelerating rate, a phenomenon known as global warming

What are the two most important insect vectors involved in the spread of bacterial and viral diseases?

mosquitoes and ticks

Sunlight consists of a wave and a particle. The particle is also known as a(an)

______ is a product of photosynthesis and is a carbon-based molecule that is the chief source of energy for most organisms.

Glucose

Which of the following is the most likely cause for the sudden sharp increase in atmospheric carbon dioxide levels?

Human activities, including the use of fossil fuels, changes in agricultural practices, and deforestation

What is the main difference in the formation of coal vs. the formation of natural gas and oil?

Natural gas and oil formed mainly from deposits of plants and animals living in oceans and coal formed mainly from the remains of plants and animals in swampy anoxic environments

Which of the following sources of alternative energy involves using uranium or other materials to split the nucleus of an atom?

Nuclear energy

What two products of the light reaction are used in the Calvin cycle?

O2 and ATP

Which of the following processes contributes the greatest amount of CO2 to the atmosphere?

The burning of fossil fuels

Which of the following best describes the effects climate change is having on tropical reef biomes?

The increase in water temperature disrupts the algae-coral symbiotic relationship, which results in death to the coral reefs.

How does climate change affect earth's oceans?

The pH level of the ocean will shift to a more acidic environment, leading to stress and the possible extinction of many species of shellfish and corals.

As global temperatures increase, which of the following scenarios are most likely to happen?

Glaciers and snow coverage decrease.

Climate change influences individuals and species by

All of the answer choices are correct.

Fossil fuels play a role in the carbon cycle

All of the answer choices are correct.

Which of the following diets would contribute to the lowest carbon footprint?

Vegan (only eating vegetable-based foods)

The average global temperature has always measured higher than the average since the

1980s

In the Calvin Cycle reaction, how would you describe CO2 fixation?

3 CO2 molecules reaction with 3 RuBP molecules to form 6 3PG molecules

In the Calvin Cycle reaction, how would you describe the regeneration of RuBP?

3 phosphates from 3 ATP molecules are added to 5 G3P molecule

Methane versus carbon dioxide are very important greenhouse gases. However, methane can retain and release about ____ times more heat than carbon dioxide.

30

Even though there are alternate energy sources, fossil fuels are used for approximately ______ of the United States energy needs

80%

If the downward slope of the line continues, what would be the expected sea ice extent in September of 2024?

All of the answer choices are correct

Which of the following is evidence that weather patterns have changed because of climate change?

All of the answer choices are correct

As climate change continues, the prevalence of vector-borne disease has increased. Why is this?

As climates have warmed and winters have become less severe, the range of mosquitos and ticks has increased, bringing with them the diseases they carry.

Desertification is an example of a biome level change that is associated with climate change. Which of the following is associated with desertification?

Associated with poor agricultural practices, including the overgrazing of cattle

Which of the following is true regarding the benefits of wind energy?

Considered to be nonpolluting

Engineer crops to withstand extremely hot temperatures.

Which of the following best describes the relationship between climate change and global warming?

The increase in temperature is one aspect of climate change and can result in the increased temperature of the planet, which is known as global warming.
