Biology paper 6 need help :S i'm chocked

[Razzle-Dazzle]

ok so i was solving past papers everything was fine....... until i came across october/2011 paper 61

the question has asked us to draw and label a feather we have never done that in school and i never so it before can someone help me???

Something similar happened to me during my mock exam ( I had to draw and label a shell) and because I had no idea what to do I just labeled what I saw on a simple drawing I made. Turns out that's all you relay have to do.
When doing your drawing make sure:

• that the picture is larger than the photograph
• you don't sketch the lines
• put down at least three labels
• Make the dawning proportionally accurate (if you have to draw a flower, don't make some of its petals look bigger unless that's how it looks in the photo.)

Guys, i was just looking at this :http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Biology (0610)/0610_s11_qp_61.pdf
I don't get the first experiment. Could you please explain? I get the iodine test but then at b) I'm lost.

i completed 3 to 4 recent papers and am planing to read some tests for food etc from my book and then i will just have a look at all the practicals in my book, just a quick look not in too much detail as i have done the book many times before

look it is fairly simple when u use the iodine test u hav a blue colour. And then they dipped the discs that were soaked in amylase into the solution so the amylase convert the sugar and now u will find a paler blue or white colour as the starch is digested to form glucose. Hope that helps ask if any more doubts
