Suggested answer: H2O

A complete answer states that each molecule contains two hydrogen atoms bonded to one oxygen atom.

Suggested answer: Albert Einstein

Einstein published special relativity in 1905 and completed general relativity in 1915.

Suggested answer: An object remains at rest or moves at constant velocity unless acted on by a net external force.

This is the law of inertia; equivalent wording that includes the net-force condition is acceptable.

Suggested answer: Mitochondria

Mitochondria carry out cellular respiration and generate much of the cell's usable ATP.

Suggested answer: It is the process by which plants and other photosynthetic organisms use light energy to make sugars from carbon dioxide and water.

A strong answer may also mention that oxygen is released and the captured energy is stored chemically.

Suggested answer: Jupiter

Jupiter is the largest planet by both mass and diameter.

Suggested answer: DNA is deoxyribonucleic acid, the molecule that stores and transmits genetic information.

A fuller answer can explain that DNA sequences contain instructions used to make functional RNA and proteins.

Suggested answer: 100 degrees Celsius

The boiling point changes when atmospheric pressure changes, so the pressure condition matters.

Suggested answer: The Moon passes between Earth and the Sun so its shadow falls on Earth.

A solar eclipse can occur only near new moon when the bodies align closely enough.

Suggested answer: Mitosis is nuclear division that produces two genetically similar daughter nuclei.

In the cell cycle it is normally followed by cytokinesis, which divides the cell's cytoplasm.

Suggested answer: To recognize and defend the body against pathogens and other harmful threats.

A strong answer can distinguish innate defenses from adaptive responses involving specialized lymphocytes and antibodies.

Suggested answer: Au

The symbol comes from the Latin name aurum.

Suggested answer: About 300,000 kilometers per second

The exact defined value is 299,792,458 meters per second.

Suggested answer: Ribosomes

Ribosomes translate messenger RNA and join amino acids into polypeptide chains.

Suggested answer: To transport oxygen around the body

Hemoglobin inside red blood cells binds oxygen; a complete answer may also mention some carbon dioxide transport.

Suggested answer: The number of protons in each atom's nucleus

The proton count defines the element; a neutral atom has the same number of electrons.

Suggested answer: The solution is acidic

At standard classroom conditions, pH 7 is neutral, values below 7 are acidic, and values above 7 are basic.

Suggested answer: When one body exerts a force on another, the second exerts an equal-magnitude, opposite-direction force on the first.

The two forces act on different bodies, which is an important part of a complete answer.

Suggested answer: Vaporization

Vaporization includes evaporation at a surface and boiling throughout a liquid.

Suggested answer: Carbon dioxide + water -> glucose + oxygen

Light energy drives the reaction; balanced symbol equations may also show water on both sides depending on the level of detail.

Suggested answer: Legislative, executive, and judicial

Congress makes federal laws, the executive branch carries them out, and federal courts interpret and apply them.

Suggested answer: 1945

Germany surrendered in May 1945 and Japan formally surrendered in September 1945.

Suggested answer: 1215

King John sealed Magna Carta at Runnymede in June 1215.

Different constitutional systems divide powers differently, but the central aim is institutional restraint and accountability.

Suggested answer: The power of a court to assess whether a law or government action is compatible with a constitution or higher law

The precise scope varies by country; in the United States, courts can decline to enforce unconstitutional acts.

Suggested answer: In a right triangle, a squared plus b squared equals c squared.

The side c is the hypotenuse, opposite the right angle.

Suggested answer: The solutions of a quadratic equation of the form ax squared plus bx plus c equals zero.

The solutions are x = (-b plus or minus the square root of (b squared minus 4ac)) divided by 2a, where a is not zero.

Suggested answer: x = 5

Subtract 5 from both sides to get 3x = 15, then divide by 3.

Suggested answer: A = pi times r squared

The area is the constant pi multiplied by the square of the radius.

Suggested answer: 2x

Apply the power rule: multiply by the exponent and reduce the exponent by one.

Suggested answer: 6

Add the values to get 18, then divide by the three values.

Suggested answer: 1/2

Three of the six equally likely outcomes are even: 2, 4, and 6.

Suggested answer: A simile makes an explicit comparison, often using 'like' or 'as'; a metaphor describes one thing as another.

Suggested answer: Weather describes short-term atmospheric conditions; climate describes longer-term patterns and averages.

A complete answer should distinguish a current event or forecast from the statistical pattern observed over many years.

Suggested answer: Stress builds where plates interact and is released when rocks slip along faults.

A full answer can describe convergent, divergent, or transform motion and the seismic waves released by sudden movement.

Suggested answer: The Equator at 0 degrees latitude

Latitude measures angular distance north or south of the Equator.

Suggested answer: Leonardo da Vinci

Leonardo began the portrait in the early sixteenth century.

Suggested answer: They describe how sellers' willingness to provide goods and buyers' willingness to purchase them interact across prices and quantities.

In a basic competitive model, their interaction helps determine market price and quantity, other things being equal.

Suggested answer: The value of the best alternative given up when a choice is made

Opportunity cost concerns the next-best forgone option, not every possible alternative combined.

Suggested answer: A sustained increase in the general price level of goods and services

Inflation reduces the purchasing power of money when incomes do not rise at the same pace.

Suggested answer: 10
