Cell phones have changed the way humans interact. Communication was very different 20 years ago, when most telephones were stationary. What does this demonstrate about the interaction and technology?
A. Cell telephones are much more affordable than they were 20 years ago.
B. The introduction of a new technology can change human activities in unexpected ways.
C. Society gradually accepted the use of cell phones, which were not allowed 20 years ago.
D. Marketing and advertising can get people to use something that they would not have used 20 years ago.
SC.8. E.5.5
The brightness of a star depends on how much light is released by the star and how far the star is from Earth. There are two ways to describe a star's brightness. Which of the following choices is the brightness seen by humans on Earth and does not depend on where the star is viewed from?
A. Initial, terminal
B. Absolute, apparent
C. Terminal, initial
D. Apparent, absolute
SC.6. E.7.4
Sometimes forest fires burn large areas of forest that are apart of the biosphere. Other than the biosphere, which of Earth’s other spheres is a forest fire most likely to affect?
A. Geosphere
B. Cryosphere
C. Atmosphere
D. Hydrosphere
SC.6. E.7.4
When energy from the sun hits the air above land, the air warms and rises. Along a coastline, cooler air above the ocean flows toward the land to replace this rising air. Which of the following best describes these processes?
A. Conduction and convection
B. Radiation and convection
C. Conduction, convection, and radiation
D. Radiation and conduction
SC.6. E.7.5
Climate change is a worldwide phenomenon. Climate change has accelerated over the past several decades. Which of the following is a human contribution to climate change?
A. Changes in the sun’s energy.
B. Changes the location relative to the sun.
C. Burning of fossil fuels.
D. Higher moisture content.
SC.6. P.13.3
The electromagnetic spectrum contains a wide range of wavelengths and frequencies. Radio waves have the longest wavelengths, while the wavelengths of gamma rays are just microscopic ripple about the length of an atomic nuclei.
Look at the diagram of the Electromagnetic Spectrum.
What conclusion can you draw about the electromagnetic radiation from the above figure?
A. Gamma rays have the shortest wavelengths, highest frequency, and highest energy.
B. Gamma rays have the shortest wavelengths, lowest frequency, and lowest energy.
D. Radio waves have the longest wavelength, highest frequency, and highest energy.
D. Radio waves have the longest wavelength, lowest frequency, and lowest energy
SC.6. P.13.1
The law of universal gravitation relates gravitational force, mass, and distance. It states that all objects attract each other through gravitational force. Which of these events is caused by contact forces?
A. Jupiter’s moons staying in orbit.
B. Picking up paper clips with a magnet.
C. High tides occurring on the East Coast.. Earthquakes along the San Andreas fault in California.
D..Earthquakes along the San Andreas fault in California.
SC.7. P.10.1
When light is passed through a glass prism, the light waves refract at different angles producing a phenomenon known as color dispersion. Color dispersion is the splitting of a light beam into its separate color components as illustrated in the diagram below.
Look at the diagram of a prism. What type of light was passed through the prism?
A. X-ray light
B. Visible light
C. Ultraviolet light
D. Infrared light
SC.7. P.10.1
Oncologists, doctors who specialize in cancer treatment often treat cancer with chemotherapy and radiation therapy. Radiation therapy uses high-energy waves to shrink cancerous tumors and damage DNA whin cancer cells. Which type of radiation do oncologists most likely use for radiation therapy?
A. X-rays and ultraviolet
B. Microwaves and radio
C. Radio and infrared
D. X-ray and gamma rays
SC.7. L.15.2
Coyotes primarily feed on small mammals, such as rabbits, squirrels, birds, and mice. Many of these animals try to escape from coyotes by burrowing into the ground. Which of the following characteristics is most likely to be naturally selected to increase a coyote population's chances for survival over time?
A. Lighter colored fur that reflects light.
B. Sharper claws that aid in digging in soil.
C. Blunt teeth that can be used for grinding.
D. Smaller ears that are less sensitive to noise.
SC.7. L.15.2
With rapid temperature swings around the world, ecosystems have been thrown into flux, exacerbating problems such as habitat loss that have already pushed many plant and animal species to the brink. Some biologists argue that Earth is on the verge of another major extinction event. Over time, the climate of a region becomes cooler. How will this affect the species living in that region?
A. Most of the current species living in the area will develop beneficial mutations, which will lead to adaptations that help them survive in the new climate.
B. All of the current species living in the region will migrate to warmer areas, while species adapted to cold-weather climate will migrate into the region.
C. All of the current species living in the area will become extinct, and the new species better adapted to the climate will form and populate the region.
D. Some species that already have cold-weather adaptations will survive, while species without cold weather adaptations may go extinct.
SC.7. L.14.4
Plants and animals are microscopic, they are very complex. They have many parts that function to keep the cell alive. Many of these parts are membrane-bound organelles that perform a specific function.
What is one main difference between the cell wall and the cell membrane?
A. The cell wall is more fragile than the cell membrane.
B. The cell wall is more rigid than the cell membrane.
C. Cell walls are only found surrounding animal cells.
D. Cell membranes are only found surrounding plant cells.
SC.8. L.18.4
Saw grass takes in light energy during photosynthesis. What happens to most of this energy.
A. It is stored as chemical energy
B. It disappears as it used up by the plant.
