Answer the following question given this paragraph: Earth is a round, three-dimensional ball. In a small area, Earth looks flat, so it is not hard to make accurate maps of a small place. When mapmakers want to map the round Earth on flat paper, they use projections. What happens if you try to flatten out the skin of a peeled orange? Or if you try to gift wrap a soccer ball? To flatten out, the orange peel must rip, and its shape must become distorted. To wrap a round object with flat paper requires lots of extra cuts and folds. A projection is a way to represent Earth's curved surface on flat paper ( Figure below ). Q: What method is used to map the earth on flat paper? Choices: - calculations - forecasts - surveying - projections A:
projections

Answer the following question given this paragraph: Protein A large part of protein digestion takes place in the stomach. The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids. In the duodenum, other enzymes trypsin, elastase, and chymotrypsinact on the peptides reducing them to smaller peptides. Trypsin elastase, carboxypeptidase, and chymotrypsin are produced by the pancreas and released into the duodenum where they act on the chyme. Further breakdown of peptides to single amino acids is aided by enzymes called peptidases (those that break down peptides). Specifically, carboxypeptidase, dipeptidase, and aminopeptidase play important roles in reducing the peptides to free amino acids. The amino acids are absorbed into the bloodstream through the small intestines. The steps in protein digestion are summarized in Figure 34.17 and Table 34.6. Q: The enzyme pepsin plays an important role in the digestion of proteins by breaking down intact protein to what short-chain amino acids? Choices: - protons - proteins - lipids - peptides A:
(Answer)
peptides
Ques: Answer the following question given this paragraph: Primary Batteries Primary batteries are single-use batteries because they cannot be recharged. A common primary battery is the dry cell (Figure 17.10). The dry cell is a zinc-carbon battery. The zinc can serves as both a container and the negative electrode. The positive electrode is a rod made of carbon that is surrounded by a paste of manganese(IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc: Zn(s) Zn 2+(aq) + 2e . Q: Primary batteries are single-use batteries because they cannot be what? Choices: - UP ticked. - refreshed - plugged - recharged A:
Ans: recharged

(A).
skeletal system
Ques:Answer the following question given this paragraph: Q: Plants supply, ultimately, most of the food eaten by terrestrial animals, along with what gas? Choices: - hydrogen - nitrogen - carbon dioxide - oxygen A:

Ans:oxygen
Ques:Answer the following question given this paragraph: Besides pathogens, many other dangers in the environment may negatively affect human health. For example, air pollution can cause lung cancer. It can also make asthma and other diseases worse. Bioterrorism is another potential threat in the environment. It may poison large numbers of people or cause epidemics of deadly diseases. But the worst thing you can do to yourself is smoke cigarettes. Q: Which pollution can cause lung cancer and can also make asthma and other diseases worse? Choices: - climate pollution - water pollution - air pollination - air pollution A:

Ans:
air pollution
