Biology Paper 6 (ATP) discussion

[Shiki Misaki]

@ mimmi: Anyways, i don't know how the drawing should actually look like but what's done is done. All we gotta do is make the best out of the remaining Biology papers.

Firstly,i drew the same central part and labelled the radical correctly but didnt labelled the stem part correctly
how many marks would be deducted

SECONDLY, i cant believe my magnification was same 1.99
But the problem is i forgot to put "X" after the value would mark be deducted ?

answer me mimmi or prince

i dont think they will sorry not sure!

Sorry bad news they will cut the mark even if the mangifiaction is right

 

[rose1700]

zero on that ?
i cant believe
this question was of three marks

-my magnification formula was correct
-my measurment was correct
-calculation were correct
-magnification was correct

only forgot to wtite x or times !

hey guys what did you put for the question where it is asked how you would make the water in the capillary tube return to zero?????????

by pressing the syringe gently , which would make water to flow into capilary tube untill the mark reaches O (zero)

I wrote what Prince wrote

 

[Heshna]

marks is not deducted for not putting x or times.... Check in mark schemes

correct expression – drawing over image ; [e.g. 50/10]
allowance for × 750;
correctly stated mag; [750 × 5 = ] × 5 / × 3750
[must be whole number for 3000 +,
up to 2 d.p. and 0.2 rounding if no allowance for × 750]

@ Prince III and pals_1010...
I also wrote the same thing...

thanks for supporting but can you specify where it is wittern that without x would be accepted ?

 

[rose1700]

Pals ,prince ,heshna anyone reply or i am gonna die ....

I drew the same thing!!.. But they are telling that we need to draw the smallest one???

That part is supposed to be the cotyledons huh?

I'm 100% sure that small thing is air space between two cotyledons as it is a cross section of the seed =S

I drew the same way as you had drawn.. But some of my friends said that we had to draw the smallest one :'(

 

[rose1700]

NO i dont think we have to drew the smallest one !
that would be toooooooo small

 

[Heshna]

U sure... because i drew the small thing...:S

 

[mimmi]

its not the smallest thing

 

[jazzangel16]

Mimmi.. I just pray that its not the small one... And besides we could clearly see that radicle and plumule right?

 

[Heshna]

0ohh..then my whole question goes wrong...because i drew the small thing and i got my magnification as 10.2..!!:S

 

[Shiki Misaki]

@ jazzangel16: You're right.. The smallest thing is just a gap in the seed.
Besides, that big fruit cannot have such a small seedling (the tiniest one). That doesn't make sense...

Edit>> Most of the students got their magnification from 1.0 to 1.9 times.
I have a 'lil doubt.. I forgot to round off the magnification number. I mean, i put 'X 1.1667 times' there. Will i be penalized for this? :S

 

[axhynic]

what if i drew only the plumule and the radical? i labelled them on the drawing so how much mark would i loose?

 

[Shiki Misaki]

@ axhynic: You've drawn the seedling including the plumule and radicle? Have you stated which part would turn into the stem and roots? Be more precise please.

 

[axhynic]

i didnt draw the whole seedling..only the plumule and radical which is on the far left side of what should actually be drawn
