What happens in cytokineses like sharing of substance or nuclear envelop forms??

Paper was ok .. kinda easy except the trna and bases questions

 

[Hisham Khan]

for potometer the answer was cm2m-1.For plasmodium answer was all mitochondria ribsome and rer .

 

[Hisham Khan]

for prokaryotes answer was cell wall cell surface membrane and ribosomes all 3

I did cm3/g/ min lol

 

[Hisham Khan]

for magnification answer was lss wavelenght more solution and 1 other option.
More magnification was wrong as it does not help us see all the cells in detail

i

I did cm3/g/ min lol

t was cm2min-1 because you measure lenght of tube with ruler and amount of water lost in tube so cm2min-1

 

[SohaibButt]

Bcoz more resolution means no detail

 

[Hisham Khan]

IT was only one correct wavelength

no I have discussed it was not only wavelenght

 

[Hisham Khan]

Does roots have plasmodesmeta no!!!

 

[SohaibButt]

N the one with sucrose n water it will pass through only phloem!!!

 

[Hisham Khan]

I am not sure about the atrioventricular one what was answer of it and the ventricle one?

root

s have symplast so plasmodesmata yes

 

[SohaibButt]

I am not sure about the atrioventricular one what was answer of it and the ventricle one?

It waa increase in pressure in artrium
