Answer the following question given this paragraph: In a fullerene, carbon atoms are bonded to three other atoms in a soccer ball pattern. The bonds are weak, so fullerenes can dissolve and form solutions. Q: In a fullerene, what atoms are bonded to three other atoms in a soccer ball pattern? Choices: - hydrogen - oxygen - positive - carbon A:
carbon

Answer the following question given this paragraph: Global air currents affect precipitation. How they affect it varies with latitude ( Figure below ). Where air rises, it cools and there is precipitation. Where air sinks, it warms and causes evaporation. These patterns are part of the global wind belts. Q: The rising and sinking of these can cause precipitation? Choices: - underwater currents - circular air currents - temporary air currents - global air currents A:
(Answer)
global air currents

Ans: 46
(Q).
Answer the following question given this paragraph: Catabolic reactions involve breaking bonds. Larger molecules are broken down to smaller ones. For example, complex carbohydrates are broken down to simple sugars. Catabolic reactions release energy, so they are exothermic. Q: What is broken during catabolic reactions, such as the breakdown of complex carbohydrates into simple sugars? Choices: - ions - forms - metals - bonds A:
(A).
bonds
Ques:Answer the following question given this paragraph: The internal resistance r can behave in complex ways. As noted, r increases as a battery is depleted. But internal resistance may also depend on the magnitude and direction of the current through a voltage source, its temperature, and even its history. The internal resistance of rechargeable nickel-cadmium cells, for example, depends on how many times and how deeply they have been depleted. Q: As a battery is depleted what happens to its internal resistance? Choices: - stagnates - changes - reduces - increases A:

Ans:increases
Ques:Answer the following question given this paragraph: Light from objects at different distances is focused by the lens of the eye. Muscles in the eye control the shape of the lens so the light is focused on the back of the eye no matter how far the object is from the lens. Q: Light from objects at different distances is focused by what part of the eye? Choices: - iris - pupil - meniscus - lens A:

Ans:
lens
