Answer the following question given this paragraph: Punta Arenas, Chile is the world's most southern city. At such a high latitude, winters are exceedingly cold and dark. Unlike the children pictured above, the children in Punta Arenas must stay inside to avoid the cold. Of course, they look forward to spring when they can go out to play. But some years, it is too dangerous for the children to go outside. The ozone hole has moved north. Too much of the Sun's harmful UV radiation gets through. Q: In some parts of the world, too much of the sun's harmful uv radiation gets through because of a hole in what layer? Choices: - mesosphere - troposphere - thermosphere - ozone A:
ozone

Answer the following question given this paragraph: The energy of the sun is first captured by producers ( Figure below ), organisms that can make their own food. Many producers make their own food through the process of photosynthesis . The "food" the producers make is the sugar, glucose . Producers make food for the rest of the ecosystem. As energy is not recycled, energy must consistently be captured by producers. This energy is then passed on to the organisms that eat the producers, and then to the organisms that eat those organisms, and so on. Q: What is type of sugar is produced through photosynthesis? Choices: - carbohydrates - insulin - glutamate - glucose A:
(Answer)
glucose
Ques: Answer the following question given this paragraph: chemical reaction: Involves a transfer of energy. There are four visual clues to indicate a chemical reaction. Q: There are how many visual clues to indicate a chemical reaction? Choices: - three - five - seven - four A:
Ans: four

Answer the following question given this paragraph: Unsaturated fatty acids occur naturally in the bent shapes shown in Figure above . However, unsaturated fatty acids can be artificially manufactured to have straight chains like saturated fatty acids. Called trans fatty acids , these synthetic lipids were commonly added to foods until it was found that they increased the risk for certain health problems. Many food manufacturers no longer use trans fatty acids for this reason. Q: What do you call the unhealthy synthetic lipids created when unsaturated fatty acids are artificially manufactured to have straight chains? Choices: - safflower acids - polyunsaturated fats - omega-3 fatty acids - trans fatty acids A:
(A).
trans fatty acids
Ques:Answer the following question given this paragraph: Position is the location of the object (whether it's a person, a ball or a particle) at a given moment in time. Displacement is the difference in the object's position from one time to another. Distance is the total amount the object has traveled in a certain period of time. Displacement is a vector quantity (direction matters), where as distance is a scalor (only the amount matters). Distance and displacement are the same in the case where the object travels in a straight line and always moving in the same direction. Q: What term is used for the difference in the placement of an object from one time to another? Choices: - variation - replacement - diffusion - displacement A:

Ans:displacement
Ques:Answer the following question given this paragraph: The global pattern of precipitation is influenced by movements of air masses. For example, there is a global belt of dry air masses and low precipitation at about 30 N and 30 S latitude. Q: The global pattern of precipitation is influenced by movements of what? Choices: - pollution masses - air valleys - clouds - air masses A:

Ans:
air masses
