1. Definitions C Click for each heading then for the answer “C” how easy study is….

2. Cartilage Smooth tissue covering ends of bones to prevent friction between bones

3. Carnivore animal that eats meat ONLY e.g. Fox

4. 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

5. 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

6. Centre of Gravity point through which all the weight of an object appears to act

7. Chemical Energy is found in the chemical bonds in food fuel and batteries

8. Chlorination adding of chlorine to drinking water to kill bacteria and prevent illness

9. Chromatography separating different colour soluble inks using a suitable solvent

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

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

12. Compound two or more different ELEMENTS chemically combined e.g. iron and sulfer make iron sulfide

13. Condensation when a gas changes to a liquid (due to cooling)

14. Conductor substance that lets heat or electricity through it

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

16. 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

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

18. Current flow of electric charge in a circuit measured in Amps (A) measured using an ammeter in series symbol is I

19. Contraception preventing fertilisation or pregnancy

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