wat was the function of the cilia? did it trap bacteria or move mucus?
-
Move mucus.
I GOT THE MONOCOT THING CORRECT IT WAS D THANK GOD!!!
-

No it was Trap bacteria, because when u breathe in, they trap the bacteria inbetween the cilia hair, but the ciliated cell produces bacteria to help trap the bacteria
-
Move mucus.

your kiddin me right! im gonna sue my teacher! :P
Its common sense! Why would the body have a mechanism to TRAP bacteria..If it was to move bacteria, it would be right, but it said trap.

Yea, what i meant was, It traps bacteria breethed in & when you exhale, it releases it

guys , i had 4 mistakes but pretty sure of the others , what do ut hink i might get ?
and about the cilia thing , i wrote it traps bacteria . cilia are the hair like projections and they trap bacteria , they can beat too to move mucus , its a tricky one , but i checked it in a cambridge reader and it waas written that it traps bacteria !!

I got one mistake so far... and it was the STUPIDEST silly mistake ever!
The question about what do aphids lack in their diet, the right answer was fats (my friend logically explained later that plants don't have fats in them, DUH!)
whereas I thought 'Wait, xylem vessels carry water, phloem vessels carry everything else, and aphids eat phloem, so they don't have water!! ;D so easy ' lol I forgot to think twice that phloem vessels carry everything else (amino acids and sugar) in a solution (water) :-[
I'm kinda doubtful about the question on meiosis and mitosis, was it non-identical and for mitosis identical or the other way round? :s
Either way i didn't revise so I guess that's reason enough :P
