Answer the following question given this paragraph: Solutions can also become supersaturated , where the amount of solute dissolved exceeds its solubility. Supersaturation most commonly occurs when a saturated solution is slowly cooled. They occur frequently in geological and meteorological processes. Supersaturated systems are unstable, and eventually, the solute will precipitate until a saturated solution is regenerated. We can quantify supersaturation by looking at solubility curves. If the ratio of solute to solvent is above the saturation curve at the given temperature, the solution is supersaturated. If it is on the curve, the solution is saturated, and if it is below the curve, the solution is unsaturated. Q: Solutions can also become supersaturated , where the amount of solute dissolved exceeds what? A:

OPTIONS:
- part solubility
- its dissolution
- its concentration
- its solubility

Answer: its solubility

Problem: OPTIONS:
- sun cycle
- tides
- weather cycle
- the water cycle
Q: Answer the following question given this paragraph: The Sun heats some areas more than others, which causes wind. The Sun's energy also drives the water cycle, which moves water over the surface of the Earth. Both wind and water power can be used as renewable resources. Q: What is driven by the sun's energy and moves water over the surface of earth? A:
Answer: the water cycle

Problem:OPTIONS:
- proteins
- fat
- air
- water

Answer the following question given this paragraph: The fluoride ion is acting as a weak Brnsted-Lowry base. The hydroxide ion that is produced as a result of the above reaction makes the solution slightly basic. Salt hydrolysis is a reaction in which one of the ions from a salt reacts with water, forming either an acidic or basic solution. Q: Salt hydrolysis is a reaction in which one of the ions from a salt reacts with what? A:
****
A: water

Answer the following question given this paragraph: Freshwater biomes have water that contains little or no salt. They include standing and running freshwater biomes. Standing freshwater biomes include ponds and lakes. Lakes are generally bigger and deeper than ponds. Some of the water in lakes is in the aphotic zone, where there is too little sunlight for photosynthesis. Plankton and plants, such as the duckweed in Figure below , are the primary producers in standing freshwater biomes. Q: Ponds and lakes are examples of what kind of biome? A:
OPTIONS:
- standing lake biome
- standing marine biome
- standing liquid biome
- standing freshwater biome
standing freshwater biome

Answer the following question given this paragraph: Ecologists look at many factors that help to describe a population. First, ecologists can measure the number of individuals that make up the population, known as population size . They can then determine the population density , which is the number of individuals of the same species in an area. Population density can be expressed as number per area , such as 20 mice/acre, or 50 rabbits/square mile. Q: How is population density expressed? A:
OPTIONS:
- per arable land
- number per household
- arable land per capita
- number per area

Answer: number per area

input with options: Answer the following question given this paragraph: Many people think that any idea that is completely accepted in science is a law. But that is not true. In science, a law is something that always applies under the same conditions. A law explains a fairly simple phenomenon. A theory is much more complex: it tells you why something happens. A law only tells you that it happens. For example, if you hold something above the ground and let go, it will fall. This phenomenon is recognized by the law of gravity ( Figure below ). Some people say that evolution is "just a theory. " But for a complex explanation like evolution, theory is the right word. Q: In science, what do you call something that always applies under the same conditions? A:
OPTIONS:
- theory
- hypothesis
- scientific method
- scientific law
output:
scientific law
