cell 3 is xylem and cell 1 is phloem, since xylem transports water it definitely has a less negative water potential than phloem
how did u know QRS is ventricular systole?QRS represents ventricular systole, so P and T must be ventricular diastole
look they have said that 1 unit on the stage micrometer is 0.1 mmmay/june 2010/11
mcq no. 3
can anyone plz help, hw is the calculatoin done ?
got two very imp qs : tissue fluid doesnt contain proteins right? i saw in a Qs answer it did. i dont have the qs though. and how to calculate net primary productivity i dont know how please help quickly

in this mcq u see that the energy that the the primary consumers use after losses is 0.75% (herbivores) whereas the total energy transfered by the producers is 1.75% so net productivity is the ratio b/w these two.got two very imp qs : tissue fluid doesnt contain proteins right? i saw in a Qs answer it did. i dont have the qs though. and how to calculate net primary productivity i dont know how please help quickly

how is the diameter 2.5 mm ?look they have said that 1 unit on the stage micrometer is 0.1 mm
and the diameter if u see is 2.5 mm
u use the formula π r ^2
so radius is 1.25mm
which in micrometers would be 125 micrometers
hence π x 125 x 125

I want to understand question "34"..why is it "B"? ^_^
Thank you, ^__^

Because it's a fact.how did u know QRS is ventricular systole?
and what exactly does recovery of ventricle walls mean?

...i never get this thing...these graphs...very confusing :/Because it's a fact.
P is atrial systole.
QRS is ventricular systole.
T is the start of ventricular diastole.
