Q: In glycolysis, glucose is split into two molecules of pyruvate. this results in a net gain of? Choices: - four atp molecules - six atp molecules - three atp molecules - two atp molecules A:
A: two atp molecules

Q: Answer the following question given this paragraph: Magnetic poles always occur in pairs of north and southit is not possible to isolate north and south poles. All magnetism is created by electric current. Ferromagnetic materials, such as iron, are those that exhibit strong magnetic effects. The atoms in ferromagnetic materials act like small magnets (due to currents within the atoms) and can be aligned, usually in millimeter-sized regions called domains. Domains can grow and align on a larger scale, producing permanent magnets. Such a material is magnetized, or induced to be magnetic. Above a material's Curie temperature, thermal agitation destroys the alignment of atoms, and ferromagnetism disappears. Electromagnets employ electric currents to make magnetic fields, often aided by induced fields in ferromagnetic materials. Q: Materials, such as iron, that exhibit strong magnetic effects are labeled what? Choices: - paramagnetic - superconducting - ultramagnetic - ferromagnetic A:
A: ferromagnetic

Q: Answer the following question given this paragraph: pressure above the liquid. Molecules in the gas phase can collide with the liquid surface and reenter the liquid via condensation. Eventually, a steady state is reached in which the number of molecules evaporating and condensing per unit time is the same, and the system is in a state of dynamic equilibrium. Under these conditions, a liquid exhibits a characteristic equilibrium vapor pressure that depends only on the temperature. We can express the nonlinear relationship between vapor pressure and temperature as a linear relationship using the ClausiusClapeyron equation. This equation can be used to calculate the enthalpy of vaporization of a liquid from its measured vapor pressure at two or more temperatures. Volatile liquids are liquids with high vapor pressures, which tend to evaporate readily from an open container; nonvolatile liquids have low vapor pressures. When the vapor pressure equals the external pressure, bubbles of vapor form within the liquid, and it boils. The temperature at which a substance boils at a pressure of 1 atm is its normal boiling point. Q: Molecules in the gas phase can collide with the liquid surface and reenter the liquid via what? Choices: - fermentation - combustion - liquidation - condensation A:
A: condensation
