Q: Answer the following question given this paragraph: Q: What do nerve impulses travel along? A:

OPTIONS:
- arteries
- pores
- membranes
- axons

A: axons

input: OPTIONS:
- in to out
- left to right
- low to high
- high to low Now, answer this question: Answer the following question given this paragraph: Cold air is dense, so it sinks. This creates a center of high pressure. Warm air is less dense so it rises. This creates a center of low pressure. Air always flows from higher to lower pressure. As the air flows, Earth's surface rotates below it causing Coriolis effect. So while the wind blows into the low pressure, it revolves in a circular pattern. This wind pattern forms a cyclone. The same happens while the wind blows out of a high pressure. This forms an anticyclone. Both are shown in Figure below . Q: How does air always flow? A:
A:
output: high to low

Answer the following question given this paragraph: The plasma membrane forms a barrier between the cytoplasm inside the cell and the environment outside the cell. It protects and supports the cell and also controls everything that enters and leaves the cell. It allows only certain substances to pass through, while keeping others in or out. The ability to allow only certain molecules in or out of the cell is referred to as selective permeability or semipermeability. To understand how the plasma membrane controls what crosses into or out of the cell, you need to know its composition. Q: The ability for a plasma membrane to only allow certain molecules in or out of the cell is referred to as what? A:

OPTIONS:
- periodic permeability
- total permeability
- moderate permeability
- selective permeability

Answer: selective permeability

Problem: OPTIONS:
- organ
- nucleus
- colony
- tissue
Q: Answer the following question given this paragraph: A tissue is a group of connected cells that have a similar function within an organism. More complex organisms such as jellyfish, coral, and sea anemones have a tissue level of organization. For example, jellyfish have tissues that have separate protective, digestive, and sensory functions. Q: What is a group of connected cells that have a similar function within an organism called? A:
Answer: tissue

Problem:OPTIONS:
- negative change
- positive change
- atmospheric change
- physical change

Answer the following question given this paragraph: A physical change is a change in one or more physical properties of matter without any change in chemical properties. In other words, matter doesn't change into a different substance in a physical change. Examples of physical change include changes in the size or shape of matter. Changes of statefor example, from solid to liquid or from liquid to gasare also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting. Four examples of physical change are pictured in the Figure below . You can learn more about physical changes and why they occur by watching the video at this URL:. Q: A change in one or more physical properties of matter without any change in chemical properties is called what? A:
****
A: physical change

Problem:OPTIONS:
- cores
- currents
- motherlode
- veins

Answer the following question given this paragraph: Underground water can be heated by magma. The hot water moves through cracks below Earth's surface. Hot water can hold more dissolved particles than cold water. The hot, salty solution has chemical reactions with the rocks around it. The water picks up more dissolved particles. As it flows through open spaces in rocks, the water deposits solid minerals. When a mineral fills cracks in rocks, the deposits are called "veins. " Figure below shows a white quartz vein. When the minerals are deposited in open spaces, large crystals grow. These rocks are called geodes. Figure below shows a "geode" that was formed when amethyst crystals grew in an open space in a rock. Q: What are the mineral deposits that fill in underground cracks called? A:
****
A:
veins
