Was #40 about the WHO and the measles thing?

no mealses question was about 29 or 30 its answer is A

40 mcq was difference between ecosystem X or Y

what of the question about the reason for uptake of water? D was the evaporation of water from the mesopyll cells and another option had to do with diffusion through the stomata.

ohh my bad was A 1 only? like only cause of wars and stuff??

i think d BECAUSE uptake of water is due to transpiration . transpiration occur due to evaporation of water from spongy mesophyll cells

ah my brain only has a RAM hehhee.. Ohh i went with D for that one ( bou the decomposers and oxygen something something)

i also think D is correct

ohh good!

is it paper was easy or difficult what was about threshold?

 

[Nisa Mirza]

is it paper was easy or difficult what was about threshold?

to be honest, the paper wasnt very easy. It had this weird and alien touch to it. I think it was the hardest of the mcp for the 3 sciences.
So hopefully the threshold would be a bit low too

GUys the question about cohesion what did you say i choose the one was no end walls

 

[Nisa Mirza]

GUys the question about cohesion what did you say i choose the one was no end walls

was confused about C and D. But went with the tubes being narrow. aint too sure tho

 

[beeloooo]

GUys the question about cohesion what did you say i choose the one was no end walls

nup it was D the narrow tube one as cohesion is a base for capillary action for the movement of water in xylem and capillary action was more appropriately defined by D!

transpiration is the movement of water out of the leave weren't we supposed to tell about the movement from ROOT to LEAF. and it had to be the absorption of water ?

 

[haidi]

but having no end walls will not break the cohesion force i think

 

[beeloooo]

but having no end walls will not break the cohesion force i think

it'll rather aid the cohesion force.

but isnt water uptake a passive process?? Instead of the water being pushed from below its pulled from above.

so were we suppose to pick an active process :/ ? argh so many confusions in this p1! -_-

am not too sure either

 

[haidi]

it will break the force between the molecules the xylem vessel is hollow continuous tube which i imp factor in i making the water to move in one body form and this is supported by having no end wall ....capillarity force water to move upward only
