(Answer)
immune
Ques: Answer the following question given this paragraph: While cells are the basic units of an organism, groups of cells can perform a job together. These cells are called specialized because they have a special job. Specialized cells can be organized into tissues . For example, your liver cells are organized into liver tissue. Your liver tissue is further organized into an organ, your liver. Organs are formed from two or more specialized tissues working together to perform a job. All organs, from your heart to your liver, are made up of an organized group of tissues. Q: What is the basic unit of an organism called? Choices: - electron - singularity - particle - cell A:
Ans: cell

Answer the following question given this paragraph: One common application of inductance is used in traffic lights that can tell when vehicles are waiting at the intersection. An electrical circuit with an inductor is placed in the road under the place a waiting car will stop over. The body of the car increases the inductance and the circuit changes sending a signal to the traffic lights to change colors. Similarly, metal detectors used for airport security employ the same technique. A coil or inductor in the metal detector frame acts as both a transmitter and a receiver. The pulsed signal in the transmitter coil induces a signal in the receiver. The self-inductance of the circuit is affected by any metal object in the path. Such detectors can be adjusted for sensitivity and also can indicate the approximate location of metal found on a person. (But they will not be able to detect any plastic explosive such as that found on the "underwear bomber. ") See Figure 23.43. Q: Metal detectors used for airport security work on which principle? Choices: - electricity - inertia - conductivity - inductance A:
(A).
inductance
Ques:Answer the following question given this paragraph: Carbon Dioxide: Every time you exhale, you release carbon dioxide into the air. It's an odorless, colorless gas. Carbon dioxide contributes to global climate change, but it isn't directly harmful to human health. Carbon Monoxide: Carbon monoxide is produced when matter burns. It's a colorless, odorless gas that is very harmful to human health. In fact, it can kill people in minutes. Because you can't see or smell carbon monoxide, it must be detected with an alarm. Q: The colorless, odorless gas released when we breath is carbon dioxide. the harmful colorless, odorless gas released when matter is burned is what? Choices: - carbon trioxide - methane - acid monoxide - carbon monoxide A:

Ans:carbon monoxide
Ques: Answer the following question given this paragraph: Continental glaciers form in a central location with ice moving outward in all directions. Alpine glaciers form in high mountains and travel through valleys. Ice caps cover large areas. Q: Which type of glaciers form in high mountains and travel through valleys? Choices: - rocky glaciers - altitude glaciers - seaside glaciers - alpine glaciers A:
Ans:
alpine glaciers
