Answer the following question given this paragraph: Hot spots may also be active at plate boundaries. This is especially common at mid-ocean ridges. Iceland is formed by a hot spot along the Mid-Atlantic Ridge. Q: What makes soil and rock particles move gradually down the slope during each thaw? A:
****
A: gravity

Answer the following question given this paragraph: This situation describes the common ion effect. A common ion is an ion that is in common to both salts in a solution. In the above example, the common ion is Ca 2+ . The common ion effect is a decrease in the solubility of an ionic compound as a result of the addition of a common ion. Adding calcium ion to the saturated solution of calcium sulfate causes additional CaSO 4 to precipitate from the solution, lowering its solubility. The addition of a solution containing sulfate ion, such as potassium sulfate, would result in the same common ion effect. Q: What is an ion that is in common to both salts in a solution? A:
OPTIONS:
- regular ion
- strong ion
- native ion
- common ion
common ion

Answer the following question given this paragraph: Hemoglobin is the iron-containing oxygen-transport protein in the red blood cells of all vertebrates. The hemoglobin molecule is an assembly of four globular protein subunits, each tightly associated with a non-protein heme group. The heme group binds to the iron ion. The most common hemoglobin is hemoglobin A, a tetramer consisting of two alpha and two beta subunits, denoted as 22. Q: What is the name of the iron-containing oxygen-transport protein in the red blood cells of all vertebrates? A:
OPTIONS:
- plasma
- platelet
- ferric acid
- hemoglobin

Answer: hemoglobin

Question: Answer the following question given this paragraph: Science is a process for developing knowledge. Change in knowledge about the natural world is expected because there is often room for new observations which may challenge current views. No matter how well one theory explains a set of observations, it is possible that a different theory may explain them just as well or better, or may also encompass a wider range of observations. Scientists are always testing and attempting to improve theories. Scientists know that even if there is no way to gain complete knowledge about something, an increasingly accurate understanding of nature will develop over time. Q: What is the process for developing knowledge called? A:
OPTIONS:
- evolution
- theory
- creationism
- science
Answer: science

input with options: Answer the following question given this paragraph: All objects in the universe have a gravitational attraction to each other ( Figure below ). The strength of the force of gravity depends on two things. They are the mass of the objects and the distance between them. The greater the objects' mass, the greater the force of attraction. As the distance between the objects increases, the force of attraction decreases. Q: The mass of the objects and the distance between them affect the strength of what universal force? A:
OPTIONS:
- states of matter
- weight
- motion
- gravity
output: gravity

Problem: OPTIONS:
- electron production
- proton transport
- glucose transport
- electron transport
Q: Answer the following question given this paragraph: Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH 2 is transferred to ATP. Q: What is the final stage of aerobic respiration? A:
Answer:
electron transport
