Answer the following question given this paragraph: Electromotive Force You can think of many different types of voltage sources. Batteries themselves come in many varieties. There are many types of mechanical/electrical generators, driven by many different energy sources, ranging from nuclear to wind. Solar cells create voltages directly from light, while thermoelectric devices create voltage from temperature differences. Q: Solar cells create voltages directly from light, while thermoelectric devices create voltage from differences in what? Choices: - oxygen - wire width - wattage - temperature A:
temperature

Answer the following question given this paragraph: Transition metals are superior conductors of heat as well as electricity. They are malleable, which means they can be shaped into sheets, and ductile, which means they can be shaped into wires. They have high melting and boiling points, and all are solids at room temperature, except for mercury (Hg), which is a liquid. Transition metals are also high in density and very hard. Most of them are white or silvery in color, and they are generally lustrous, or shiny. The compounds that transition metals form with other elements are often very colorful. You can see several examples in the Figure below . Q: Transition metals are superior conductors of heat as well as what else? Choices: - light - radiation - cold - electricity A:
(Answer)
electricity
Ques: Answer the following question given this paragraph: Some birds have lost the ability to fly during the course of their evolution. Several flightless birds are shown in Figure below . They include the ostrich, kiwi, rhea, cassowary, and moa. All of these birds have long legs and are adapted for running. The penguins shown in the figure are also flightless birds, but they have a very different body shape. That's because they are adapted for swimming rather than running. Q: The ostrich, kiwi, rhea, cassowary, and moa are examples of what kind of birds? Choices: - predators - raptors - prehistoric - flightless A:
Ans: flightless
(Q).

(A).
a phospholipid bilayer
Ques:Answer the following question given this paragraph: Poor air quality started to become a serious problem after the Industrial Revolution. The machines in factories burned coal. This released a lot of pollutants into the air. After 1900, motor vehicles became common. Cars and trucks burn gasoline, which adds greatly to air pollution. Q: During what time period did poor air quality become a problem? Choices: - Chernobyl disaster - coal industry boom - second world war - industrial revolution A:

Ans:industrial revolution
Ques: Answer the following question given this paragraph: Deposit feeders, which are organisms that feed on small pieces of organic matter, usually in the top layer of soil. Sea cucumbers are deposit feeders, living on the ocean floor. They eat the tiny scrap particles that are usually abundant in the environments that they inhabit. Q: What are are organisms that feed on small pieces of organic matter? Choices: - bottom feeders - difference feeders - waste feeders - deposit feeders A:
Ans:
deposit feeders
