Biology 1
The cell structure where genetic material is stored and controls the cell’s activities.
What is the Nucleus?
The process by which plants use light energy to produce glucose from carbon dioxide and water.
What is photosynthesis?
The type of bond formed when electrons are shared between non-metal atoms.
What is Covalent Bonding?
A reaction in which an acid reacts with a base to form a salt and water.
What is Neutralisation?
The energy stored in an object due to its position in a gravitational field.
What is gravitational potential energy?
The process by which glucose is broken down in cells to release energy.
What is Respiration?
The hormone released by the pancreas that lowers blood glucose levels by increasing uptake of glucose by cells.
What is insulin?
The smallest particle of an element that can exist and retains its chemical properties.
What is an Atom?
The state in which the forward and reverse reactions occur at the same rate in a closed system.
What is Dynamic Equilibrium?
The rate at which energy is transferred.
What is Power?
The process by which ribosomes use mRNA to assemble amino acids into a protein.
What is Translation?
The process by which water evaporates from plant leaves, creating a pull that draws water up through the xylem.
What is Transpiration?
The arrangement of elements in order of increasing atomic number, with elements showing repeating chemical properties in groups.
What is the Periodic Table?
The minimum energy needed for particles to react when they collide.
What is Activation Energy?
A wave in which the oscillations are perpendicular to the direction of energy transfer.
What is a Transverse Wave?
The change in allele frequency within a population over generations due to differential reproductive success.
What is natural selection?
The mechanism by which the body maintains a stable internal environment, including regulation of temperature and blood glucose.
What is Homoeostasis?
A technique used to separate mixtures based on differences in boiling point, involving evaporation and condensation.
What is Distillation?
An object by which the speed of a reaction is increased by lowering the energy required for successful collisions to occur.
What is a Catalyst?
The change in direction of a wave when it passes from one medium to another.
What is Refraction?
The stage of mitosis during which chromosomes are pulled apart to opposite poles of the cell.
What is Anaphase?
The condition in plant cells where internal pressure pushes the cytoplasm against the cell wall, helping maintain structural support in non-woody plants.
What is Turgidity?
The process used to convert a gas into a liquid by cooling and/or applying pressure.
What is Liquefaction?
A reaction in which a single substance breaks down into two or more simpler substances.
What is Thermal Decomposition?
The relationship where the total energy in a closed system remains constant, although it can be transferred between stores.
What is Conservation of Energy?
