Answer the following question given this paragraph: Q: What is a decrease in the magnitude of the membrane potential? Choices: - digestion - ionization - inflammation - depolarization A:
depolarization
Answer the following question given this paragraph: Conversely, very large forces are created by liquids and solids when they try to expand but are constrained from doing sowhich is equivalent to compressing them to less than their normal volume. This often occurs when a contained material warms up, since most materials expand when their temperature increases. If the materials are tightly constrained, they deform or break their container. Another very common example occurs when water freezes. Water, unlike most materials, expands when it freezes, and it can easily fracture a boulder, rupture a biological cell, or crack an engine block that gets in its way. Other types of deformations, such as torsion or twisting, behave analogously to the tension, shear, and bulk deformations considered here. Q: Conversely, very large forces are created by liquids and solids when they try to expand but are constrained from doing sowhich is equivalent to compressing them to less than their normal volume. this often occurs when a contained material warms up, since most materials expand when they do this? Choices: - increase density - increase mass - decrease temperature - increase temperature A:
increase temperature
Q: Answer the following question given this paragraph: Magnetism is the ability to be attracted by a magnet and to act as a magnet. Only ferromagnetic materials have this property. They include iron, cobalt, and nickel. When these materials are magnetized, they become temporary or permanent magnets. Magnetite is a natural permanent magnet. Q: What is the ability to be attracted by a magnet and to act as a magnet? Choices: - electrical attraction - polarization - inertia - magnetism A:
A: magnetism
Question: Answer the following question given this paragraph: After the film is developed, any unexposed silver bromide must be removed by a process called "fixing"; otherwise, the entire film would turn black with additional exposure to light. Although silver bromide is insoluble in water, it is soluble in a dilute solution of sodium thiosulfate (Na2S2O3; photographer's hypo) because of the formation of [Ag(S2O3)2]3 ions. Thus washing the film with thiosulfate solution dissolves unexposed silver bromide and leaves a. Q: After the film is developed, any unexposed silver bromide must be removed by a process called what? Choices: - watering - sweeping - washing - fixing A:
Answer: fixing

Answer the following question given this paragraph: 15.6 Entropy and the Second Law of Thermodynamics: Disorder and the Unavailability of Energy Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process. The ultimate fate of the universe is likely to be thermodynamic equilibrium, where the universal temperature is constant and no energy is available to do work. Entropy is also associated with the tendency toward disorder in a closed system. Q: What is the loss of energy available to do work called? Choices: - negentropy - force - power - entropy A:
**Answer**
entropy
