Answer the following question given this paragraph: Although California is prone to many natural hazards, including volcanic eruptions at Mt. Shasta or Mt. Lassen, and landslides on coastal cliffs, the natural hazard the state is linked with is earthquakes. In this video, the boundaries between three different tectonic plates and the earthquakes that result from their interactions are explored. Q: What natural disaster is california most linked with? Choices: - fires - volcanoes - hurricanes - earthquakes A:
earthquakes

Answer the following question given this paragraph: A soil is a residual soil when it forms in place. Only about one third of the soils in the United States form this way. The material comes from the underlying bedrock. Residual soils form over many years since it takes a long time for solid rock to become soil. First, cracks break up the bedrock. This may happen due to ice wedging. Weathering breaks up the rock even more. Then plants, such as lichens or grasses, become established. They cause further weathering. As more time passes and more layers of material weather, the soil develops. Q: Soil that forms in place over a very long period is called what? Choices: - leakage soil - antique soil - resultant soil - residual soil A:
(Answer)
residual soil
Ques: Answer the following question given this paragraph: As Melvin Calvin discovered, carbon fixation is the first step of a cycle. Like an electron transport chain, the Calvin Cycle, shown in Figure below , transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transfer chain, excited electrons lose energy to NADPH and ATP. In the Calvin Cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose. Q: Carbon fixation is the first step of what cycle involving light reactions? Choices: - sun cycle - life cycle - water cycle - calvin cycle A:
Ans: calvin cycle
(Q).
Answer the following question given this paragraph: The amino acid sequence is the primary structure of a protein. As explained in Figure below , a protein may have up to four levels of structure, from primary to quaternary. The complex structure of a protein allows it to carry out its biological functions. Q: What sequence is the primary structure of a protein? Choices: - processed acid sequence - proteins acid sequence - nucleic acid sequence - amino acid sequence A:
(A).
amino acid sequence
Ques:Answer the following question given this paragraph: Primary pollutants enter the air directly. Some are released by natural processes, like ash from volcanoes. Most are released by human activities. They pour into the air from vehicles and smokestacks. Several of these pollutants are described below. Q: Ash that enters the air naturally as a result of a volcano eruption is classified as what kind of pollutant? Choices: - thick pollutant - secondary pollutant - natural pollutant - primary pollutant A:

Ans:primary pollutant
Answer the following question given this paragraph: Zinc is a silvery metal that quickly tarnishes to a blue-gray appearance. This change in color is due to an adherent coating of a basic carbonate, Zn2(OH)2CO3, which passivates the metal to inhibit further corrosion. Dry cell and alkaline batteries contain a zinc anode. Brass (Cu and Zn) and some bronze (Cu, Sn, and sometimes Zn) are important zinc alloys. About half of zinc production serves to protect iron and other metals from corrosion. This protection may take the form of a sacrificial anode (also known as a galvanic anode, which is a means of providing cathodic protection for various metals) or as a thin coating on the protected metal. Galvanized steel is steel with a protective coating of zinc. Q: A protective coating of zinc to prevent corrosion is applied to steel and other metals labeled what? Choices: - polarized - battered - corroded - galvanized A:
galvanized
