Biology ATP discussion.

As 24 hours have passed, lets start discussing the paper. What did you write the answer for the part in which it was asked : "which seedling survived and why?'' ...something like that

 

[sksuriza]

the green ones.. as they have chlorophyll can manufacture food n all

 

[izzahzainab]

same here

 

[unfortunatediva]

i messed up the skin labeling part :\ is arteriole acceptable for blood capillary network ?
n is the third one hair follicle or hair papilla :S ?

 

[izzahzainab]

im sure that u will lose 1 mark for writing arterioles BUT you have saved yourself 2 marks for the part b of that question stating their "involvement". you must have written arterioles dilate, which is correct (not capillaries dilate, a common mistake).

 

[Silent Hunter]

did we have to make the pericarp too?

 

[punkprincess143]

wht wr da markz for lik wch seedling will surviv?? rmmbr?
n wht we hd 2 writ in lik wht indicatn abt inherritnc iz total gvin??

 

[punkprincess143]

anybudy thre?? rply!

That question had 3 marks.The indication about inheritance one had 4 marks. I guess, in that, you had to mention that green seedlings were dominant (from the approximate ratio of 3 :1 derived from the total). They were heterozygous dominant and the white ones were homozygous recessive. Monohybrid inheritance. Discontinous variation.

 

[punkprincess143]

mine ws same =) bt da ans 4 seedlingz 1 i thot thy wr askin 'bout particular dishz n i wrot 4 da green seeedlingz in dish A! cz thy shwd lik thy bettr grminatd! :'(((

 

[abcde]

Aww.. I understand. But please don't worry. It's no use crying over spilt milk now, punkprincess. Forget it! It doesn't matter if you lose a few marks. Don't let that affect your confidence. Focus on the papers ahead instead. Best of luck!

 

[talharulz]

what was the magnification??????

 

[abcde]

I think about x560.

 

[talharulz]

570 over here

 

[talharulz]

was that label hair folicle or hair papilla?????

 

[Soulgamer]

hair follicle and X560 was the magnification....

 

[abcde]

Hair papilla.

 

[Soulgamer]

hair papilla is the base where the blood vessels are located beneath the hair follicle...each hair follicule has nerve endings attached(papilla)

 

[sksuriza]

a had more seedlingd


so if thy wd have asked abt dish it wud be b

 

[Silent Hunter]

well talking about seedling DISH A had less..............so many ov ma friends wrote that as dish A had less so less competition for food and water and they grow well than dish B
