user: Answer the following question given this paragraph:   When fuel is burned, most of the energy is released as heat. Some of this heat can be used to do work. Heat cooks food or warms your house. Sometimes the heat is just waste heat. It still heats the environment, though.   Q: When fuel is burned, most of the energy is released in what form?   Choices:  - precipitation  - carbon dioxide  - humidity  - heat  A:
heat

Answer the following question given this paragraph:   Any two waves in the same medium undergo wave interference as they pass each other. At the location where the two waves collide, the result is essentially a summation of the two waves. In some places, a wave crest from one source will overlap a wave crest from the other source. Since both waves are lifting the medium, the combined wave crest will be twice as high as the original crests. Nearby, a wave trough will overlap another wave trough and the new trough will be twice as deep as the original. This is called constructive interference because the resultant wave is larger than the original waves. Within the interference pattern, the amplitude will be twice the original amplitude. Once the waves pass through each other and are alone again, their amplitudes return to their original values.   Q: What is it called when two waves in the same medium pass one another?   Choices:  - accumulation  - frequency  - synchrony  - interference  A:
(Answer)
interference


Ques: Answer the following question given this paragraph:   Four interactions stabilize the tertiary structure of a protein: (a) ionic bonding, (b) hydrogen bonding, (c) disulfide linkages, and (d) dispersion forces. When a protein contains more than one polypeptide chain, each chain is called asubunit. The arrangement of multiple subunits represents a fourth level of structure, the quaternary structure of a protein. Hemoglobin, with four polypeptide chains or subunits, is the most frequently cited example of a protein having quaternary structure Saylor URL: http://www. saylor. org/books.   Q: Hemoglobin, with four polypeptide chains or subunits, is the most frequently cited example of a protein having what kind of structure?   Choices:  - binary  - unary  - ternary  - quaternary  A:
Ans: quaternary

Answer the following question given this paragraph:   Passive transport occurs when a substance passes through the cell membrane without needing any energy to pass through. This happens when a substance moves from an area where it is more concentrated to an area where it is less concentrated. Concentration is the number of particles of a substance in a given volume. Let's say you dissolve a teaspoon of salt in a cup of water. Then you dissolve two teaspoons of salt in another cup of water. The second solution will have a higher concentration of salt.   Q: When substances pass through the cell membrane without needing any energy what is it called?   Choices:  - active transport  - kinetic transport  - energetic transport  - passive transport  A:
(A).
passive transport
