Q: Answer the following question given this paragraph: Wind blows small particles away. As a result, the ground surface gets lower and rockier; this is called deflation . The rocks that are left are called desert pavement . Desert pavement is a surface covered by gravel-sized particles that are not easily moved by wind. Q: What is the process by which wind blows to make the ground surface gets lower and rockier ? A:

OPTIONS:
- inflation
- stagnation
- layering
- deflation

A: deflation

Problem: OPTIONS:
- repeat energy
- mechanical energy
- new energy
- potential energy
Q: Answer the following question given this paragraph: Why do charges flow in an electric current? The answer has to do with electric potential energy. Potential energy is stored energy that an object has due to its position or shape. An electric charge has potential energy because of its position in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where their potential energy is lower. This is similar to water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What is the scientific term for stored energy an object has due to its position or shape? A:
Answer: potential energy

A: lipids

Problem:OPTIONS:
- solid mosaic model
- sensors mosaic model

- fluid mosaic model

Answer the following question given this paragraph: Fluid Mosaic Model In 1972, S. Singer and Garth L. Nicolson proposed a new model of the plasma membrane that, compared to earlier understanding, better explained both microscopic observations and the function of the plasma membrane. This was called the fluid mosaic model. The model has evolved somewhat over time, but still best accounts for the structure and functions of the plasma membrane as we now understand them. The fluid mosaic model describes the structure of the plasma membrane as a mosaic of componentsincluding phospholipids, cholesterol, proteins, and carbohydratesin which the components are able to flow and change position, while maintaining the basic integrity of the membrane. Both phospholipid molecules and embedded proteins are able to diffuse rapidly and laterally in the membrane. The fluidity of the plasma membrane is necessary for the activities of certain enzymes and transport molecules within the membrane. Plasma membranes range from 510 nm thick. As a comparison, human red blood cells, visible via light microscopy, are approximately 8 m thick, or approximately 1,000 times thicker than a plasma membrane. (Figure 3.18). Q: What model describes the structure of the plasma membrane as a mosaic of components? A:
****
A:
fluid mosaic model
