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:
- one
- three
- four
- two
Q: Answer the following question given this paragraph: If a cell were a house, the plasma membrane would be walls with windows and doors. Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport and active transport. Q: In how many basic was can substances cross the plasma membrane? A:
Answer: two

Problem:OPTIONS:
- molecules
- particles
- cells
- proteins

Answer the following question given this paragraph: Digestive enzymes secreted in the acidic environment (low pH) of the stomach help break down proteins into smaller molecules. The main digestive enzyme in the stomach is pepsin , which works best at a pH of about 1.5. These enzymes would not work optimally at other pHs. Trypsin is another enzyme in the digestive system, which breaks protein chains in food into smaller parts. Trypsin works in the small intestine, which is not an acidic environment. Trypsin's optimum pH is about 8. Q: Digestive enzymes secreted in the acidic environment (low ph) of the stomach help break down what? A:
****
A: proteins

Answer the following question given this paragraph: Fluoride ion is widely used in water supplies to help prevent tooth decay. Chloride is an important component in ion balance in blood. Iodide ion is needed by the thyroid gland to make the hormone thyroxine. Q: Fluoride ion is widely used in water supplies to help prevent what? A:
OPTIONS:
- rust
- bacteria
- chlorine taste
- tooth decay
tooth decay

Answer the following question given this paragraph: Atoms form covalent bonds by sharing valence electrons. The valence electrons are located in atomic orbitals. However, when a bond forms, the structure of the atomic orbitals changes. In this lesson, we will see how the atomic orbitals interact to share valence electrons and form different types of covalent bonds. Q: What do atoms form by sharing valence electrons? A:
OPTIONS:
- phenotype bonds
- neutron bonds
- ionic bonds
- covalent bonds

Answer: covalent bonds

input with options: Answer the following question given this paragraph: Neutralization reactions between an acid and a base yield a salt and water. In some cases, this results in a completely neutral solution. However, some salts are weakly acidic or basic. How can we tell whether a given salt will act as an acid or base? Looking at the relative strengths of the acid and base that were used to form the salt can give us information on the acid-base properties of the resulting solution. Q: What kind of reactions between an acid and a base yield a salt and water? A:
OPTIONS:
- oxidation
- evaporation
- distillation
- neutralization
output:
neutralization
