Answer the following question given this paragraph: Summary The concentration of a substance is the quantity of solute present in a given quantity of solution. Concentrations are usually expressed as molarity, the number of moles of solute in 1 L of solution. Solutions of known concentration can be prepared either by dissolving a known mass of solute in a solvent and diluting to a desired final volume or by diluting the appropriate volume of a more concentrated solution (a stock solution) to the desired final volume. Q: The concentration of a substance is the quantity of solute present in a given quantity of ___________? A:
OPTIONS:
- structure
- mixture
- salutation
- solution
solution

Answer the following question given this paragraph: available; if arsenic is an essential trace mineral in human diets, it is probably required on the order of 50 ppb or less. A toxic dose of arsenic corresponds to about 7,000 ppb and higher, which is over 140 times the trace amount that may be required by the body. Thus, arsenic is not poisonous in and of itself. Rather, it is the amount that is dangerous: the dose makes the poison. Similarly, as much as water is needed to keep us alive, too much of it is also risky to our health. Drinking too much water too fast can lead to a condition called water intoxication, which may be fatal. The danger in water intoxication is not that water itself becomes toxic. It is that the ingestion of too much water too fast dilutes sodium ions, potassium ions, and other salts in the bloodstream to concentrations that are not high enough to support brain, muscle, and heart functions. Military personnel, endurance athletes, and even desert hikers are susceptible to water intoxication if they drink water but do not replenish the salts lost in sweat. As this example shows, even the right substances in the wrong amounts can be dangerous!. Q: Drinking too much water too fast can lead to what potentially fatal condition, which causes dangerous changes to salt levels? A:
OPTIONS:
- inebriation
- osmosis
- drowning
- water intoxication

Answer: water intoxication

Question: Answer the following question given this paragraph: 2. The second step in eukaryotic cell division is division of the cell's nucleus. This includes division of the chromosomes. This step is called mitosis. It is a complex process that occurs in four phases. The phases of mitosis are described below. Q: The second step in eukaryotic cell division is division of which part of the cell? A:
OPTIONS:
- protons
- molecules
- Cell Division
- nucleus
Answer: nucleus

input with options: Answer the following question given this paragraph: Gap genes themselves are under the effect of maternal effect genes, such as bicoid and nanos. Gap genes also regulate each other to achieve their precise striped expression patterns. The maternal effect is when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype. This often occurs when the mother supplies mRNA or proteins to the egg, affecting early development. In developing Drosophila, maternal effects include axis determination. Q: What is the term for when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype? A:
OPTIONS:
- congenital effect
- uterine effect
- oceanic effect
- maternal effect
output: maternal effect
