Answer the following question given this paragraph: Each substance can be classified as an ionic solute or a nonionic solute. Ionic solutes are electrolytes, and nonionic solutes are nonelectrolytes. Potassium chloride is an ionic compound; therefore, when it dissolves, its ions separate, making it an electrolyte. Fructose is a sugar similar to glucose. (In fact, it has the same molecular formula as glucose. ) Because it is a molecular compound, we expect it to be a nonelectrolyte. Isopropyl alcohol is an organic molecule containing the alcohol functional group. The bonding in the compound is all covalent, so when isopropyl alcohol dissolves, it separates into individual molecules but not ions. Thus, it is a nonelectrolyte. Magnesium hydroxide is an ionic compound, so when it dissolves it dissociates. Thus, magnesium hydroxide is an electrolyte. Q: What are ionic solutes? Choices: - solvent - salts - carbohydrates - electrolytes A:
electrolytes
Q: Answer the following question given this paragraph: Mechanical advantage equals the distance of effort divided by the distance the object moves. It is also equal to the output force divided by the input force. Q: What advantage equals the distance of effort divided by the distance the object moves and is also equal to the output force divided by the input force? Choices: - potential - atomic - constant - mechanical A:
A: mechanical
Question: Answer the following question given this paragraph: Q: Inducible enzymes usually function in what type of pathways? Choices: - enzymatic - anabolic - biogenic - catabolic A:

Answer the following question given this paragraph: Convection is the transfer of thermal energy by particles moving through a fluid. Particles transfer energy by moving from warmer to cooler areas. That's how energy is transferred in the soup in Figure above . Particles of soup near the bottom of the pot get hot first. They have more energy so they spread out and become less dense. With lower density, these particles rise to the top of the pot (see Figure below ). By the time they reach the top of the pot they have cooled off. They have less energy to move apart, so they become denser. With greater density, the particles sink to the bottom of the pot, and the cycle repeats. This loop of moving particles is called a convection current . Q: Convection is the transfer of thermal energy by particles moving through what? Choices: - Solid - tissue - Metal - fluid A:
**Answer**
fluid
