these are the possible structures they can ask...

Cool. Thanks.

yaro itni khap kis cheez ki ha.......vo na to mushkil labelling karvatay hainOR na he XEROPHYTES PLASMOLYSIS mai sai kuch ana ha.......believe me isko apny lye khud tough mat bnao!!!!

Hey guys quick question, might benefit you too
-Ok so when we add 1cm3 HCL to 2cm3 test solution and boil
-we add Sodium hydrogen carbonate after to neutralise..
QUESTION: how much Sodium hydrogen carbonate??? Volume?

 

[aleezay]

Ho
How was your P2?

Not as good as my expectations lol not that im relaxed about the remaining papers or anything, but with only hours left before the paper, theres not much u can prepare, not much u can do except for telling yourself to calm down, so yeah..

the two yellow parts are the guard cells, and the green part b/w them is ur stomata. remember, guard cells control the opening and closing of stomata

I dont think so.
Idk what the yellow is but the green are guard cells bro.
Typical shape

in high power diagram if we see nucleus and its stained so do we draw the chromatin threads. And if we see nucleolus so do we draw the nucleus?

 

[rabos1]

i know the feeling bro

Also, math and phy on Wednesday!

Its not specified.We'd be given a ph indicator and we'll have to keep adding the Nahco3 in small amounts and test them with the ph indicator till the pH returns to neutral.

^hun aenj vi nai ae atleast a C makes it ! but always aim high

Haha i know that.. He exaggerated a little.. But chalo saray din ki itni khap k baad C to aa jae ga na.. if not an A (IA)

u r right. the yellow parts r the subsidiary cells that surround the guard cell, the green part IS the GUARD CELL. srry 4 the mistake B4.

how will i know if i have to join the points or draw a curve in graph?

 

[beeloooo]

guys goodluck ! dont panic do it with focus ! and pray for me created this thread dont forget ! Allah Hafiz

OHHHHH thats how we'd use that!
Thankyouuuu!!!

lol.Np
From what i've heard.We'd be given a ph paper :s not sure though. But it will have range of colours for every pH.And the end point (point of neutralisation) would probably green.

Right!

Another confusion if you'd be kind enought to help is with the biuret test! (w/NaOH)
-We add 2cm3 test sol. To a test tube
-1cm3 NaOH
-AND add CuSo4 and i read "drop by drop"
How much of CuSo4??

all ive read is just a few drops.. not the exact number..

P2 was the main paper.. jo hona tha ho to gya he..
IA,IA

P4 ki weightage sab say ziada hay. I have P4 on 24th. It all depends on that. Magar shukar hay P2 pehli dafa sahi ho gya.

 

[Malik777]

Pray for me too

Hmmm ok then a few drops it is.
