Answer the following question given this paragraph: Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded. In breccia, the stones are angular. Sandstone is made of sand-sized particles. Siltstone is made of smaller particles. Silt is smaller than sand but larger than clay. Shale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. Q: How are classic sedimentary rocks group? Choices: - particle depth - density - color - size of sediment A:
size of sediment

Answer the following question given this paragraph: All materials have some resistance, but certain materials resist the flow of electric current more or less than other materials do. Materials such as plastics have high resistance to electric current. They are called electric insulators. Materials such as metals have low resistance to electric current. They are called electric conductors. Q: Materials such as metals have low resistance to electric current, what are they called? Choices: - electric channel - electric channels - electric conduit - electric conductors A:
(Answer)
electric conductors
Ques: Answer the following question given this paragraph: In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan ( Figure below ). Q: When a mountain stream flows onto flatter land and comes to a stop rapidly, what do the deposits form? Choices: - conical fan - vertical fan - upstream fan - alluvial fan A:
Ans: alluvial fan
(Q).
Answer the following question given this paragraph: Amino acids join together to form a molecule called a dipeptide. The OH from the carboxyl group of one amino acid combines with a hydrogen atom from the amino group of the other amino acid to produce water (blue). Q: What is the molecule, dipeptide formed together by? Choices: - polymer acids - rna acids - acetic acids - amino acids A:
(A).
amino acids
Ques:Answer the following question given this paragraph: Many people have problems with their vision , or ability to see. Often, the problem is due to the shape of the eyes and how they focus light. Two of the most common vision problems are nearsightedness and farsightedness, which you can read about below. You may even have one of these vision problems yourself. Usually, the problems can be corrected with contact lenses or lenses in eyeglasses. In many people, they can also be corrected with laser surgery, which reshapes the outer layer of the eye. For a video about vision problems, go to this URL: http://www. youtube. com/watch?v=ekSGbXt4XdI. Q: What are the two most common vision problems? Choices: - colorblindness and farsightedness - glaucoma and nearsightedness - colorblindness and nearsightedness - nearsightedness and farsightedness A:

Ans:nearsightedness and farsightedness
Answer the following question given this paragraph: Chemical reactions either absorb or release energy, which can be in the form of electricity. Electrochemistry is a branch of chemistry that deals with the interconversion of chemical energy and electrical energy. Electrochemistry has many common applications in everyday life. All sorts of batteries, from those used to power a flashlight to a calculator to an automobile, rely on chemical reactions to generate electricity. Electricity is used to plate objects with decorative metals like gold or chromium. Electrochemistry is important in the transmission of nerve impulses in biological systems. Redox chemistry, the transfer of electrons, is behind all electrochemical processes. Q: What is the name of a branch of the chemistry that deals with the interconversion of chemical energy and electrical energy? Choices: - Inorganic chemistry - Biochemistry - Theoretical Chemistry - electrochemistry A:
electrochemistry
