Answer the following question given this paragraph: Solar energy is used to heat homes and water, and to make electricity. Scientists and engineers have many ways to get energy from the Sun ( Figure above ). One is by using solar cells. Solar cells are devices that turn sunlight directly into electricity. Lots of solar cells make up an individual solar panel. You may have seen solar panels on roof tops. The Sun's heat can also be trapped in your home by using south facing windows and good insulation. Q: The sun's heat can also be trapped in your home by using south facing windows and good what? Choices: - floors - vegetation - curtains - insulation A:
insulation

Answer the following question given this paragraph: Oil (red) is found in the porous rock layer (yellow) and trapped by the impermeable layer (brown). The folded structure has allowed the oil to pool so a well can be drilled into the reservoir. Q: Oil is found in the porous rock layer and trapped by the what? Choices: - \ - crystalline layer - mantle - impermeable layer A:
(Answer)
impermeable layer

Ques:Answer the following question given this paragraph: Delocalization of the electrons makes for a more stable molecule than a similar molecule that does not have delocalized electrons. Benzene is a more stable and less reactive compound than straight-chain hexenes. The sp 2 hybridization of the carbon atoms results in a planar molecule as opposed to the puckered structure of cyclohexane. Benzene rings are common in a great number of natural substances and biomolecules. The figure below shows the structural formulas for vanilla and naphthalene. Naphthalens is a chemical which is commonly used in mothballs. Q: Naphthalens is a chemical which is commonly used in what? Choices: - shampoo - fertilizers - inhalers - mothballs A:

Ans:mothballs
Answer the following question given this paragraph: Use an electron microscope. This instrument has a resolution many times greater than a light microscope, and can be used to see the details on the outside of a cell. Some electron microscopes can also be used to see the details inside a cell. Q: What instrument has a resolution many times greater than a light microscope, and can be used to see the details on the outside of a cell? Choices: - complex microscope - element microscope - molecular microscope - electron microscope A:
electron microscope
