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

Answer: al

Problem: OPTIONS:
- roots
- leaves
- stems
- fruit
Q: Answer the following question given this paragraph: Q: What do some plants produce that protects dormant seeds and aids in their dispersal? A:
Answer: fruit

Problem:OPTIONS:
- increasing the resistance
- increasing the heat
- decreasing the heat
- decreasing the resistance

Answer the following question given this paragraph: There are two ways to control the current in a circuit. Since the current is directly proportional to the potential difference and inversely proportional to the resistance, you can increase the current in a circuit by increasing the potential or by decreasing the resistance. Q: Besides increasing the potential, how else can you increase current in a circuit? A:
****
A: decreasing the resistance

Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Although the kidneys are the main organs of excretion, several other organs also excrete wastes. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system . This lesson focuses on the role of the kidneys in excretion. The roles of the other excretory organs are summarized below:. Q: Excretion is the process of removing excess water and wastes from the body. what are the main organs of excretion? A:
OPTIONS:
- eyes
- lungs
- brains
- kidneys
kidneys

Answer the following question given this paragraph: An element is a fundamental chemical part of a substance; there are about 115 known elements. A compound is a combination of elements that acts as a different substance; there are over 50 million known substances. Q: What is the name for a combination of elements that acts as a different substance? A:
OPTIONS:
- contrast
- mixture
- solution
- compound

Answer: compound

input with options: Answer the following question given this paragraph: Figure 29.17 shows a comet with two prominent tails. What most people do not know about the tails is that they always point away from the Sun rather than trailing behind the comet (like the tail of Bo Peep's sheep). Comet tails are composed of gases and dust evaporated from the body of the comet and ionized gas. The dust particles recoil away from the Sun when photons scatter from them. Evidently, photons carry momentum in the direction of their motion (away from the Sun), and some of this momentum is transferred to dust particles in collisions. Gas atoms and molecules in the blue tail are most affected by other particles of radiation, such as protons and electrons emanating from the Sun, rather than by the momentum of photons. Q: Why do comet tails always point away from the sun instead of trailing behind the comet? A:
OPTIONS:
- dust particles attract
- dust particles evaporate
- dust particles liquify
- dust particles recoil
output:
dust particles recoil
