Cartilage

Smooth tissue covering ends of bones

to prevent friction between bones

Carnivore

• animal that eats meat ONLY • e.g. Fox

Catalyst

• chemical that speeds up (or slows down) a chemical reaction

• but is not used up in the reaction

• e.g. manganese dioxide in making oxygen from hydrogen peroxide

Cell

• basic building block (or unit) of life

A = Vacuole

B = Nucleus

C= Cytoplasm

D = Cell membrane

E = Cell Wall

F = Cell sap in vacuole

G = Chloroplast

Centre of Gravity

• point through which

• all the weight of an object

• appears to act

Chemical Energy

• is found in the chemical bonds in• food• fuel and• batteries

Chlorination

• adding of chlorine to drinking water to kill bacteria and prevent illness

Chromatography

• separating different colour soluble inks using a suitable solvent

Competition

• when two or more organisms • fight for something in short supply • e.g. birds fight for worms

Chemical Change

• happens when at least one new substance is formed e.g. burn a match makes ash

Compound

• two or more different ELEMENTS chemically combined

• e.g. iron and sulfer make iron sulfide

Condensation

• when a gas changes to a liquid • (due to cooling)

Conductor

• substance that lets heat or electricity through it

Conduction

• movement of heat • through a solid• without the particles moving out of place• e.g. poker in fire

Convection

• movement of heat• through a liquid or gas• by the movement of the particles around the container• e.g. hot air rises and cold air falls • e.g. water heating in a kettle

Covalent Bond• is formed when • a pair of electrons are shared • between two atoms• e.g. water or hydrogen gas

Current

• flow of electric charge in a circuit

• measured in Amps (A)

• measured using an ammeter in series

• symbol is I

Contraception• preventing fertilisation or pregnancy

Chromosomes found in the nucleus of cells carry genes which control how we look etc.Made of DNA and protein
