Respiration: The process of releasing energy from glucose, either aerobically or anaerobically.

Photosynthesis: The process by which plants convert light energy into chemical energy (glucose).

Multicellular Organisms: Organisms composed of many cells organised into tissues, organs, and systems.

Structure and Bonding: The study of ionic, covalent, and metallic bonding and intermolecular forces.

Ionic Bonding: The electrostatic attraction between positive and negative ions.

Covalent Bonding: The sharing of electron pairs between atoms.

Metallic Bonding: The attraction between positive metal ions and delocalised electrons.

Intermolecular Forces: Forces between molecules, including van der Waals and hydrogen bonding.

Enthalpy: The heat content of a chemical system at constant pressure.

Kinetics: The study of reaction rates and the factors affecting them.

Equilibrium: A state where forward and reverse reaction rates are equal.

pH: A measure of the acidity or alkalinity of a solution.

Organic Chemistry: The study of carbon-containing compounds and their reactions.

Analytical Techniques: Methods for identifying and quantifying substances, such as chromatography, spectroscopy, and mass spectrometry.

Hardware: The physical components of a computer system.

Software: The programs and data that run on computer hardware.

Algorithm: A step-by-step procedure for solving a problem.

Pseudocode: An informal, human-readable description of an algorithm.

Database: An organised collection of structured data.

SQL (Structured Query Language): The language used to manage and query relational databases.

Network: A collection of computers connected to share resources.

Operating System: Software managing computer hardware and providing services for programs.

CPU (Central Processing Unit): The processor that executes instructions.

RAM (Random Access Memory): Temporary storage for data and programs in use.

Polynomial: An expression with variables and coefficients combined using addition, subtraction, and multiplication.

Surd: An irrational number expressed as a root, such as √2.

Indices (Exponents): Rules for working with powers: multiplication, division, power of a power.

Trigonometric Functions: Sine, cosine, and tangent, relating angles to side ratios in right-angled triangles.

Calculus: The study of rates of change (differentiation) and accumulation (integration).

Differentiation: Finding the rate of change of a function with respect to a variable.

Integration: Finding the area under a curve or the antiderivative of a function.

Vectors: Quantities with both magnitude and direction.

Scalar Product: The dot product of two vectors, resulting in a scalar.

Normal Distribution: A bell-shaped probability distribution used in statistics.

Kinematics: The study of motion without considering forces.

Dynamics: The study of forces and their effect on motion.

Newton’s Laws: Three laws describing the relationship between forces and motion.

Momentum: The product of mass and velocity, conserved in collisions.

Work: Energy transferred when a force moves an object through a distance.

Power: The rate at which work is done or energy is transferred.

Electromagnetic Spectrum: The range of all electromagnetic radiation, from radio waves to gamma rays.

Quantum Phenomena: Behaviour of matter and energy at atomic and subatomic scales.

Wave Properties: Wavelength, frequency, amplitude, and speed of waves.

Radioactivity: The spontaneous emission of radiation from unstable atomic nuclei.
