Chingoo:
How can one live in the same community but not the same habitat? They say both of them lived in the same area of a forest and grassland. They didn't say one of them lived in the grassland and other the forest, no? A community is different species living at the same place at the same time...so most likely, a common habitat.

That's what I'm talking about, why else would they mention the same area , which is actually the definition of habitat "same area" :D  Somebody ask his biology teacher plz :P

what did u guys write for questions 1-3

and what about the 2 questions concerning the heart... one with the electircal impulse diagram nd the other talking about the a heart disease in which the semi lunar valve where damaged or something like that...

also there was a question about seive tube elements in photosynthesising plants and in actively growing roots... ??
finally... question 40..???

if you guys could answer my questions above that would be more than great....   :)

1- B
2- C
3- B

for the electircal impulses diagram it was option B. P and T one.
and for the heart disease it was option D. the one which said the left ventrical gets enlarged.
for the sieve tubes one sucrose would move out in the roots while water potential in the leaves increases. i guess that was option D.
and for 40 the correct ans was decrease decrease. i chose the wrong option for this one :-[

THEY DO NOT HAVE THE SAME HABITAT, IT CLEARLY SAYS ONE WAS IN A FOREST AND THE OTHER IN GRASSLAND. THEY LIVE IN THE SAME COMMUNITY AND THEY ARE THE SAME TROPHIC LEVEL.

for the cells question yeah it was D, and i think it was something like 2 and 4,  3 and 5.
but yeah D.

for the processes question, it was all of them.

for the magnification question, Mitochondria Can Be Seen Under The Microscope thats right, BUT in that choice you had ER too, and you cant see ER, so it was C, because even there are a number of differently sized mitochondrion's so yeah i dont know.

how in the hell is it increase, increase? moderate exercise=deeper breathing=higher tidal volume so X will clearly decrease!
