Question 2

• The following items are added to a test tube and
  allowed to stand for 45 minutes
• 2 ml of IKI
• 5 ml of distilled yeast culture after
  fermentation
• 3 ml of 1.5M NaOH
• Which of the following results would you expect?

Question 2

• A brick red precipitate indicating the presence
  of a reducing sugar.
• A white precipitate indicating the
  presence of CO2 gas.
• A dark red colour indicating starch.
• No precipitate because the reducing sugar will
  have totally fermented.
• A yellow precipitate indicating ethanol.

Question 6

• What does this diagram tell you about
  photosynthesis?

Nothing. It tells you the the pigments of a leaf
absorb energy in the 400-500nm and 600 to 700nm
range
