Answer the following question given this paragraph: At a geothermal power plant, engineers drill wells into the hot rocks. Hot water or steam may come up through the wells. Alternatively, water may be put down into the well to be heated. It then comes up. The hot water or steam makes a turbine spin. This makes electricity. Pictured below is an example of a geothermal power plant ( Figure below ). Q: Drilling wells into hot rocks to release hot water or steam is an example of what kind of power plant? Choices: - hydroelectric - solar - fossil fuel - geothermal A:
(Answer)
geothermal
Ques: Answer the following question given this paragraph: AcidBase Titrations Because most common acids and bases are not intensely colored, a small amount of an acid base indicator is usually added to detect the equivalence point in an acidbase titration. The point in the titration at which an indicator changes color is called theendpoint. The procedure is illustrated in Example 21. Q: The point in the titration at which an indicator changes color is called what? Choices: - zeta point - tipping point - chromatic point - end point A:
Ans: end point
(Q).
Answer the following question given this paragraph: The most widely accepted theory explaining how muscle fibers contract is called the sliding filament theory . According to this theory, myosin filaments use energy from ATP to "walk" along the actin filaments with their cross bridges. This pulls the actin filaments closer together. The movement of the actin filaments also pulls the Z lines closer together, thus shortening the sarcomere. Q: What is the most widely accepted theory explaining how muscle fibers contract? Choices: - sliding pigment theoery - sliding tritium theory - sliding carbon theory - sliding filament theory A:
(A).
sliding filament theory
Ques:Answer the following question given this paragraph: Aging occurs as cells lose their ability to divide. Q: Aging occurs as cells lose their ability to do what? Choices: - fold - split - duplicate - divide A:

Ans:divide
Ques: Answer the following question given this paragraph: Electron affinity is the energy required for an electron to be added to a neutral atom in its gaseous form. Because most atoms release energy when an electron is added, most electron affinity values are negative. These values generally become more negative (more energy is released) as you move left to right across the table or from bottom to top. Q: What is the name for the energy required for an electron to be added to a neutral atom in its gaseous form? Choices: - mass affinity - neutron affinity - photon affinity - electron affinity A:
Ans:
electron affinity
