• if you eat too much fat what health problem would you get?


  heart disease
• if you eat too much sugar what health problem would you get?

  tooth decay
• if you don’t eat enough protein what health problem would you get?


  poor growth
• if you don’t eat enough carbohydrate what health problem would you get 


  not much energy
• explain why eating a lot of chips every day is bad for your health

  because you wouldn’t get all of your 7 nutrients which can lead to malnutrition and cause diseases such as scurvy and rickets
• glucose is aborbed in the small intestine - what carries glucose from the intestine to other parts of the body


  red blood cells
• distillation

• chromatography 


  diagram B - box
• filtration


  diagram C - funnel
• the liquid in the jug is brown because the parts of the coffee beans are _____ in water

  soluble
• some bits of coffee beans are left on the filter because they are ______ in water

  insoluble
• the brown liquid which drips through the filter is a ______ of coffee


  solution
• how could John get dry, solid coffee from the brown liquid in the jug of coffee


  by using distillation - boiling the water so that all is left is coffee
• John tried making a cup of coffee in the same way using cold water. He used 800cm of cold water and the same amount of ground up coffee beans - the liquid in the jug was a lighter colour why was this?


  Because coffee doesn’t dissolve as much in cold water
• How much solid coffee would John get back from this liquid 


  Less than before
• Gary’s results - which colour of food colouring contained the banned food dye

  Yellow
• Gary’s results - which colour of food colouring contained the most dye


  Brown
• Gary’s results - which colour of food colouring did not dissolve in the water?


  Red
• Carbon monoxide, nicotine and tar can get into the lungs when a person smokes - how does carbon monoxide effect the body?


  causes red blood cells to carry less oxygen
• Carbon monoxide, nicotine and tar can get into the lungs when a person smokes - how does nicotine effect the body?


  causes addiction to smoking
• Carbon monoxide, nicotine and tar can get into the lungs when a person smokes - how does tar effect the body?


  causes lung cancer
• Give a change in the coronary artery when a person smokes


  The arteries sides have carved and formed a smaller stream for cells to flow down
• Explain why a blood clot in the coronary artery prevents muscle cells in the heart from respiring normally?


  Because since respiring takes place in the heart if an artery is blocked then the red blood cells can’t reach the heart for respiring
• Which processes occur during distillation


  Evaporation then condensation
• Give two ways in which the water vapour changes as it passes down the glass tube in the condenser


  It cools down

  It turns into water again
