input with options: Answer the following question given this paragraph: character increases. Silicates contain anions that consist of only silicon and oxygen. Aluminosilicates are formed by replacing some of the Si atoms in silicates by Al atoms; aluminosilicates with threedimensional framework structures are called zeolites. Nitrides formed by reacting silicon or germanium with nitrogen are strong, hard, and chemically inert. The hydrides become thermodynamically less stable down the group. Moreover, as atomic size increases, multiple bonds between or to the group 14 elements become weaker. Silicones, which contain an SiO backbone and SiC bonds, are high-molecular-mass polymers whose properties depend on their compositions. Q: Aluminosilicates are formed by replacing some of the si atoms in silicates by which atoms? A:
OPTIONS:
- fe
- ce
- ad
- al
output: al

Q: Answer the following question given this paragraph: CHAPTER SUMMARY 35.1 Neurons and Glial Cells The nervous system is made up of neurons and glia. Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues. There are four main types of neurons: unipolar, bipolar, multipolar, and pseudounipolar neurons. Glia are non-neuronal cells in the nervous system that support neuronal development and signaling. There are several types of glia that serve different functions. Q: What anatomical system is made up of neurons and glia? A:

OPTIONS:
- reproductive system
- lymphatic system
- digestive system
- nervous system

A: nervous system

input: OPTIONS:
- stomach and excretory
- heart and excretory
- stomach and nervous
- respiratory and excretory Now, answer this question: Answer the following question given this paragraph: The organs of the excretory system are also parts of other organ systems. For example, your lungs are part of the respiratory system. Your lungs remove carbon dioxide from your body, so they are also part of the excretory system. More organs of the excretory system are listed below ( Table below ). Q: What two systems are the lungs part of? A:
A:
output: respiratory and excretory

Answer the following question given this paragraph: Mammalian teeth are also important for digestion. The four types of teeth are specialized for different feeding functions, as shown in Figure below . Together, the four types of teeth can cut, tear, and grind food. This makes food easier and quicker to digest. Q: In mammals, four specialized types of what serve to cut, tear, and grind food? A:

OPTIONS:
- scales
- plates
- spines
- teeth

Answer: teeth

Problem: OPTIONS:
- generational alterations
- eukaryotic alterations
- mutational alterations
- chromosomal alterations
Q: Answer the following question given this paragraph: Chromosomal Alterations. Chromosomal alterations are major changes in the genetic material. Q: What term is used to describe major changes in the genetic material? A:
Answer: chromosomal alterations

Answer the following question given this paragraph: Research is being done into alternative crops for biofuels. A very promising alternative is algae. Algae appears to be a better biofuel than corn. Algae is much easier to convert to a usable fuel. Growing algae requires much less land and energy than crops. Algae can be grown in locations that are not used for other things. For example, they can be grown in desert areas where food crops are not often grown. Corn must be grown where food crops are grown. This can reduce the land and water available for growing food. Algae can be fed agricultural and other waste, so valuable resources are not used. Much research is being done to bring these alternative fuels to market. Q: What is algae easier to covert into that corn is currently used for? A:

OPTIONS:
- oil
- food
- sugar
- fuel

Answer:
fuel
