    But the second logic could be that in dark, dark green leaves are least likely to be developed.

    Leaves in plant have more darker chlorophyll if more green light is reflected.

    That "Some other knowledge" is the SECOND LOGIC i posted !! -__-"

    In this question answer will be B. because the rate has to be faster, so concentration will be more, and the H2 has to be double, so same volume will be used because we are already using double concentration: No. of moles in Q > 10/1000 * 0.2 = 1/500 (double moles, in P moles are 1/1000)

    YES. That's what i did. But the second logic could be that in dark, dark green leaves are least likely to be developed.

    green colour due to chlorophyll in chloroplasts. Chlorophyll actually reflects the green light in the spectrum (vibgyor) to get its characteristic colour. Plants in light will have dark colour, means more green light is reflected, and those in dark will have light green colour. IDK about the no...

    Spidey21 The question in our atp was related to a specific type of leaves, so light had different effects on it. If i'm not wrong...

    Maybe a contradictory question :D

    Yea, but as ashiqbal said, why would zinc in powdered form not affect the rate?

    NOOO, less light will result in less green leaves! In our atp, it was a specific type of leaf. In general, leaves need light to be green.

    No, but after germination it is essential ! Here, seeds that germinated in dark, the new shoots had no light and therefore most of them would develop pale green leaves (less light-green light reflected less-pale green colour).

    I said 'almost' the same, so if x=o, the total would 405, that's the nearest to 430. other options will give greater differences :p :)

    23) It's just a dye that loses its colour due to CO2 ( see the question, it says the dye loses its colour in tissues actively respiring) Answer is D since in Cotyledons digestion is taking place, which needs energy. In radicle and plumule, respiration takes place for growth. 26) B , Fact. C...

    I guess the route i posted was correct! Because in dialysis we draw the blood from artery, and not vein.

    The water in iii will evaporate slowly, this will allow zinc sulphate in the solution to saturate and the particles will likely clump together to form big crystals by the time the water has evaporated.

    can anyone explain me the route taken by the urea before excretion.. Renal artery contains urea, and renal artery is like a sub-artery of aorta, so does aorta contain urea?! Urea comes from liver, and the hepatic vein goes to the heart.. it contains urea, so is it like that urea goes all the way...
