Q: Answer the following question given this paragraph: Plants may not be able to move to another location, but they are able to change how they grow in response to their environment. Growth toward or away from a stimulus is known as a tropism ( Table below ). Auxins, a class of plant hormones, allow plants to curve in specific directions as they grow. The auxin moves to one side of the stem, where it starts a chain of events that cause rapid cell growth on just that one side of the stem. With one side of the stem growing faster than the other, the plant begins to bend. Q: What plant hormone allows plants to curve in a specific direction? A:
Answer: auxin

Problem:OPTIONS:
- storms
- landslides
- winds
- currents

****
A: currents

Answer the following question given this paragraph: Soils may also remain in place but become degraded. Soil is contaminated if too much salt accumulates. Soil can also be contaminated by pollutants. Q: What natural resource can be damaged by the accumulation of too much salt? A:
OPTIONS:
- forests
- sediment
- mineral
- soil

Answer the following question given this paragraph: Summary 12.1 Chemical Reaction Rates The rate of a reaction can be expressed either in terms of the decrease in the amount of a reactant or the increase in the amount of a product per unit time. Relations between different rate expressions for a given reaction are derived directly from the stoichiometric coefficients of the equation representing the reaction. 12.2 Factors Affecting Reaction Rates The rate of a chemical reaction is affected by several parameters. Reactions involving two phases proceed more rapidly when there is greater surface area contact. If temperature or reactant concentration is increased, the rate of a given reaction generally increases as well. A catalyst can increase the rate of a reaction by providing an alternative pathway that causes the activation energy of the reaction to decrease. 12.3 Rate Laws Rate laws provide a mathematical description of how changes in the amount of a substance affect the rate of a chemical reaction. Rate laws are determined experimentally and cannot be predicted by reaction stoichiometry. The order of reaction describes how much a change in the amount of each substance affects the overall rate, and the overall order of a reaction is the sum of the orders for each substance present in the reaction. Reaction orders are typically first order, second order, or zero order, but fractional and even negative orders are possible. 12.4 Integrated Rate Laws Differential rate laws can be determined by the method of initial rates or other methods. We measure values for the initial rates of a reaction at different concentrations of the reactants. From these measurements, we determine the order of the reaction in each reactant. Integrated rate laws are determined by integration of the corresponding differential. Q: The rate of a reaction can be expressed either in terms of the decrease in the amount of what or the increase in the amount of a product per unit time? A:
OPTIONS:
- plasma
- sulfate
- isotope
- reactant

Answer: reactant

Question: Answer the following question given this paragraph: The electrode at which reduction occurs is called the cathode . The cathode gradually increases in mass because of the production of copper metal. The concentration of copper(II) ions in the half-cell solution decreases. The cathode is the positive electrode. Q: What is the electrode at which reduction occurs called? A:
OPTIONS:
- reducthode
- anode
- cathine
- cathode
Answer: cathode

input: OPTIONS:
- Big Bang theory
- flat earth theory
- string theory
- plate tectonics Now, answer this question: Answer the following question given this paragraph: The theory of plate tectonics explains most of the features of Earth's surface. Plate tectonics helps us to understand where and why mountains form. Using the theory, we know where new ocean floor will be created and where it will be destroyed. We know why earthquakes and volcanic eruptions happen where they do. We even can search for mineral resources using information about past plate motions. Plate tectonics is the key that unlocks many of the mysteries of our amazing planet. Q: What theory explains most of the features of earth's surface? A:
A:
output:
plate tectonics
