Answer the following question given this paragraph: The dense, iron core forms the center of the Earth. Scientists know that the core is metal. The inner core is solid, and the outer core is molten. Here are some of the reasons they know this:. Q: Which layer of the earth is molten? Choices: - the inner core - the metallic core - the mantle - the outer core A:
the outer core
(Question)
Answer the following question given this paragraph: Sodium chloride crystals are cubic in shape. Other ionic compounds may have crystals with different shapes. Q: What type of shape does sodium chloride have? Choices: - round - trianguler - oblong - cubic A:
(Answer)
cubic
Ques: Answer the following question given this paragraph: Through the process of conduction, heat flows from warmer objects to cooler objects ( Figure below ). The lower mantle is heated directly by conduction from the core. In conduction , heat is transferred as atoms collide. Q: What process involves the flow of heat from warmer objects to cooler objects? Choices: - activation - convection - radiation - conduction A:
Ans: conduction
(Q).
Answer the following question given this paragraph: After equilibrium has been reached, the concentrations of all reaction components will remain constant unless a change is made to the system. Because the concentrations are no longer changing, it may appear that the reaction has "stopped. " This is incorrect; both the forward and reverse reactions are still going on, even at equilibrium. However, because the two reactions are proceeding at the same rate, no net change is observed. Q: After what state is reached, the concentrations of all reaction components remain constant unless a change is made to the system? Choices: - homeostasis - level - equality - equilibrium A:
(A).
equilibrium
Ques:Answer the following question given this paragraph: Q: The fact that water in a reservoir is elevated above the ground means that it has what kind of energy? Choices: - excessive - nuclear - kinetic - potential A:

Ans:potential
Answer the following question given this paragraph: After hatching, most arthropods go through one or more larval stages before reaching adulthood. The larvae may look very different from the adults. They change into the adult form in a process called metamorphosis. During metamorphosis, the arthropod is called a pupa. It may or may not spend this stage inside a special container called a cocoon. A familiar example of arthropod metamorphosis is the transformation of a caterpillar (larva) into a butterfly (adult) (see Figure below ). Distinctive life stages and metamorphosis are highly adaptive. They allow functions to be divided among different life stages. Each life stage can evolve adaptations to suit it for its specific functions without affecting the adaptations of the other stages. Q: What is the process of larva becoming an adult called? Choices: - parthenogenesis - synthesis - evolution - metamorphosis A:
metamorphosis
