that area is the vascular bundle and we know the xylem cells are inwards while phloem are out and xylem transports water and minerals

fr amylase its 7 and fr lipase andprotease i guess alkaline cux its secreted from pancreas which can make it alkaline

and what about temp?

 

[asma tareen]

and what about temp?

but most pf the enzymes are released by pancreas which have an alkaline and most proteases are released in the small intestine and that stomach thing confuses me too temp is 37 fr all enzymes

isB the ans??

 

[Tulaib]

any notes available for biology?

 

[TheStallion-Reborn]

isB the ans??

yea..but why??

 

[asma tareen]

yea..but why??

cux its a reflex action and brain is involved and in reflex actions brain is only informed its not involved except for PUPILARY REFLEX

 

[Zuhsid]

isB the ans??

i think it is!!

do tel me its ans i just remember got it wrong in mocks

 

[Zuhsid]

do tel me its ans i just remember got it wrong in mocks

lol....i got it wrong in the mocks too!! Tho the correct ans is A....

Even the examiner report dint explain it explicitly!!!

maybe its possible cux xhanging water will make testa softer and will remove it which can help in germination maybe

 

[asma tareen]

Even the examiner report dint explain it explicitly!!!

but A is logocal

 

[Tulaib]

Even the examiner report dint explain it explicitly!!!

as water is necessary for testa to break open, so increasing the level of water until enough water is absorbed by seed is necessary, and then the seeds may grow

yeah me 2 chose this answer in mocks due to this reason!

my fluke works most of the time in these cases
