Q: Answer the following question given this paragraph: The ability to see is called vision. The brain and eyes work together to allow us to see. The eyes collect and focus visible light and change it to electrical signals that travel to the brain. The brain interprets the signals and "tells" us what we are seeing. Q: What are the organs work together to allow us to see? A:

OPTIONS:
- lungs
- heart
- nose
- brain and eyes

A: brain and eyes

input: OPTIONS:
- mobility cells
- molecules
- skin cells
- nerve cells Now, answer this question: Answer the following question given this paragraph: Cells, like these nerve cells, do not work in isolation. To send orders from your brain to your legs, for example, signals pass through many nerve cells. These cells work together to perform a similar function. Just as muscle cells work together, bone cells and many other cells do as well. A group of similar cells that work together is known as a tissue. Q: When orders are sent from your brain to your legs, these signals pass through what type of cells? A:
A:
output: nerve cells

Answer the following question given this paragraph: Science rests on evidence and logic, so it deals only with things that can be observed. An observation is anything that is detected either through human senses or with instruments and measuring devices that extend human senses. Things that cannot be observed or measured by current meanssuch as supernatural beings or eventsare outside the bounds of science. Consider these two questions about life on Earth:. Q: What term means anything that is detected either through human senses or with instruments and measuring devices that extend human senses? A:

OPTIONS:
- variation
- evaluation
- evacuation
- observation

Answer: observation

Problem: OPTIONS:
- acidic neutrons
- acidic electrons
- acidic proteins
- acidic protons
Q: Answer the following question given this paragraph: Strong acids completely transfer their acidic protons to the solvent when dissolved in water. When a weak acid is dissolved in water, most of the molecules will retain their acidic protons, and only a small percentage will dissociate. Q: When dissolved in water, what do strong acids transfer to the solvent completely? A:
Answer: acidic protons

Problem:OPTIONS:
- third
- none of the above
- first
- second

Answer the following question given this paragraph: Newton's second law shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration. The relationship between mass and acceleration, on the other hand, is an inverse relationship. The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force. Q: Which of newton's law shows that there is a direct relationship between force and acceleration? A:
****
A: second

Problem:OPTIONS:
- viscosity
- homeostasis
- friction
- elasticity

Answer the following question given this paragraph: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL:. Q: What property means that something can return to its original shape after being stretched or compressed? A:
****
A:
elasticity
