7 is a prime number because it is only divisible by 1 and itself. The other numbers have additional divisors that disqualify them as primes.

Water is composed of two hydrogen atoms and one oxygen atom, which forms the chemical formula H2O. The other formulas represent different compounds entirely.

Asia is recognized as the largest continent by land area due to its vast geographic expanse. The other continents, while significant, cover less area.

A verb describes actions or states of being, making it the correct answer. Other parts of speech such as nouns, adjectives, and adverbs serve different roles in sentence structure.

Under standard atmospheric pressure at sea level, water boils at 100°C. The alternative temperatures do not correspond to water's boiling point under normal conditions.

Adding 5 to both sides yields 3x = 21, and dividing by 3 results in x = 7. This straightforward solution highlights basic algebraic manipulation.

Photosynthesis is the process in which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The other processes refer to different biological functions.

William Shakespeare is the renowned playwright behind 'Romeo and Juliet'. His works continue to be studied for their profound impact on literature and drama.

Carbon is assigned the atomic number 6 and is a fundamental element in organic compounds. The other elements have different atomic numbers and characteristics.

Paris is the capital of France and a major center for art, culture, and history. The other cities named are capitals of other nations.

Since the sum of angles in a triangle is 180°, and two of the angles are 90° and 30°, the remaining angle must be 60°. This deduction relies on basic geometric principles.

Historically, the Nile River has been regarded as the longest river in the world despite some debates. This recognition is based on longstanding geographical research.

Nitrogen constitutes roughly 78% of the Earth's atmosphere, making it the main component. The other gases, though important, exist in much smaller amounts.

The Pythagorean theorem states that the sum of the squares of the two legs of a right triangle equals the square of its hypotenuse. This theorem is a cornerstone of geometry.

Mitosis is the process by which somatic cells divide to produce two genetically identical daughter cells. This is distinct from meiosis, which is involved in the creation of gametes.

Substituting x = 3 into the function yields 2(9) - 3(3) + 5, which simplifies to 18 - 9 + 5 = 14. This evaluation requires accurate substitution and arithmetic operations.

The storming of the Bastille on July 14, 1789, is recognized as the spark that ignited the French Revolution. This pivotal event reshaped France and had profound effects on European history.

The Electron Transport Chain, located in the mitochondria, is the primary site where ATP is generated during aerobic respiration. Although glycolysis and the Krebs cycle contribute, the bulk of ATP is produced in this chain.

Sublimation is the process by which a substance transitions directly from its solid state to a gaseous state, bypassing the liquid phase. This distinguishes it from deposition, evaporation, and condensation, which involve other state changes.

The quadratic formula provides a direct solution for the roots of any quadratic equation, regardless of whether it factors neatly. While completing the square is a valid alternative, the quadratic formula is generally more reliable for non-factorable equations.
