Oh sorry..i had to go..mom you know...ahh....
Well i think my teacher wrote the wrong year...i searched for all 2013, but its not there...
but did you understand how do draw a plan diagram?
its like you should only draw the layers of different cells, and the lines should be all straight and you have to mark at-least 3 things on your drawing, if they dont really specify that mark vascular bundle(for example)

Should we mark always? As in even when they don't ask us to?

Paper 32 will probably involve investigating the effect of something on the activity of an enzyme that coagulates milk.

How did you know that Paper 32 will probably involve investigating the effect of something on the activity of an enzyme that coagulates milk.

 

[mohamedehab97]

Are there any predictions for the microscopic slide in Paper 32

Question #2a1 thats it

 

[Autumngirl]

I have a question about diagrams. When we are told to draw a cell in which the chromatin in the nucleus is clearly visible, how do we draw it? All I can think of is a mess of squiggles or a shaded region but aren't both these things penalized in the mark schemes? They always say clear outlines and no shading so I'm pretty confused. If anyone has any idea, please share. Thanks!

Question #2a1 thats it

It asks you to use the line between J and R and eye piece graticule scale to find the length. Which means you have to start all your reading from J and count the number in divisions it takes from J to L/M/N/P.

From P to L it should be 2 units! Do the rest and you'll know
