Ques: Q: As temperature increases, the solubility of the majority of solid substances does what? Read this paragraph and choose the correct option from the provided answers: The solubility of the majority of solid substances increases as the temperature increases. However, the effect is difficult to predict and varies widely from one solute to another. The temperature dependence of solubility can be visualized with the help of a solubility curve , a graph of the solubility vs. temperature (see Figure below ). Choices: - stays the same - reduces - mutates - increases A:
Ans: increases

Ques: Q: What does fiber help keep at normal levels in the body? Read this paragraph and choose the correct option from the provided answers: Fiber is a complex carbohydrate that consists mainly of cellulose and comes only from plants.

Ques: Q: Why does water infiltrate the ground? Read this paragraph and choose the correct option from the provided answers: Water infiltrates the ground because soil and rock are porous. Between the grains are pores, or tiny holes. Since water can move through this rock it is permeable. Eventually, the water reaches a layer of rock that is not porous and so is impermeable. Water stops moving downward when it reaches this layer of rock. Choices: - gravity - prolonged drought conditions - run-off from flooding - because soil and rocks are porous A:
Ans:
because soil and rocks are porous
